RESUMEN
BACKGROUND: Peganum harmala L. is used in traditional medicine to treat several health ailments. Hence, the present work aimed to investigate the DPPH free radical scavenging, α-amylase, cytotoxic, and antifibrotic effects of the hydrophilic extract and fixed oil obtained from P. harmala seeds. METHODS: The hydrophilic extract and fixed oil of P. harmala were assessed for their abilities to scavenge DPPH free radicals and inhibit α-amylase using reference bioassays. The cytotoxicity was assessed on several cancer and normal cell lines, including B16F1, Caco-2, COLO205, HeLa, Hep 3B and Hep G2, MCF-7, and HEK-293 T cells. The MTS assay was used to evaluate the antifibrotic capabilities utilizing the human hepatic stellate (LX-2) cell line. RESULTS: P. harmala plant fixed oil has potent DPPH free radical scavenging activity with an IC50 dose of 79.43 ± 0.08 µg/ml. Besides, the hydrophilic extract has a poor anti-α-amylase effect compared with the antidiabetic drug Acarbose, with IC50 doses of 398 ± 0.59 and 25.11 ± 1.22 µg/ml, respectively. In addition, the growth of MCF-7, Hep3B, HepG2, HeLa, COLO205, CaCo2, B16F1, and HeK293t was inhibited by P. harmala hydrophilic extract with IC50 doses of 121.34 ± 1.71, 268.3 ± 0.75, 297.20 ± 1.00, 155.60 ± 1.14, 150.01 ± 0.51, 308.35 ± 0.53, 597.93 ± 1.36, and 5.38 ± 0.99 µg/ml, respectively. In addition, at 1000 µg/ml, 5-Fluorouracil reduced fibrosis cells by 0.089%, while the hydrophilic extract decreased the number of LX-2 cells by 5.81%. CONCLUSION: P. harmala plant-fixed oil exhibits potential antioxidant properties. While the hydrophilic extract showed limited effectiveness as an anti-α-amylase agent and demonstrated notable cytotoxic effects against various tested cancer cell lines. Furthermore, this extract significantly reduces the number of LX-2 fibrotic cells. These findings emphasize the therapeutic potential of these products in managing various health disorders and warrant further investigation into their mechanisms of action and clinical applications.

Peganum harmala seeds crude hydro-methanolic extract and their fractions (obtained with ethyl acetate and butan-1-ol) were analyzed and compared for their chemical profiles of alkaloids and polyphenols content. Moreover, their antioxidant, a-glucosidase, acetylcholinesterase, and butyrylcholinesterase inhibitory activities were evaluated. The butan-1-ol fraction revealed the highest total phenolic content and exhibited the highest antioxidant capacity. From the inhibitory enzyme evaluations, it should be highlighted the butan-1-ol fraction inhibitory potential of É-glucosidase (the IC50= 141.18±4µg/mL), which was better than the acarbose inhibitory effect (IC50= 203.41±1.07 µg/mL). The extracts' chemical profile analysis revealed several compounds, in which quercetin dimethyl ether, harmine and harmaline emerged as the major compounds. The different solvents used impacted Peganum harmala seed contents and biological responses. Statistical analysis showed a significant correlation between bioactive compounds and biological activities. Thus, Peganum harmala seeds could be a promising natural source of bioactive compounds at the crossroads of many human diseases, and its cultivation may be encouraged.
RESUMEN
Peganum harmala L., a traditional medicinal plant in China, is renowned for its significant alkaloid content in seeds and roots exhibiting a wide range of pharmacological activities, including antidepressant, antiseptic, and antiviral. However, the volatile composition of the herb remained unclear. Apart from that, the extraction of volatile compounds through essential oil presents challenges due to the low yield and the degradation of volatile active compounds at high temperatures. This study used multiple sample preparation methods including headspace (HS), needle trap device (NTD), and liquid-liquid extraction (LLE) coupled with gas chromatography-mass spectrometry (GC-MS) to analyze the volatile compounds from the areal part of P. harmala L.. A total of 93 compounds were identified with NTD facilitating the first detection of harmine among the volatile organic compounds. Through network pharmacology and protein interaction analysis, the compounds' potential therapeutic targets of the compounds were explored, and 23 key targets were obtained (AKT1, ALB, PTGS2, MAOA, etc). KEGG pathway enrichment analysis indicated significant involvement in neuroactive ligand-receptor interactions and serotonergic synapses. The results enhanced the understanding of P. harmala's pharmacological mechanisms and supported its ethnopharmacological use.

During the last decade, nanotechnology has attained a significant place among the scientific community for the biosynthesis of plant-based nanoparticles owing to its effective, safe, and eco-friendly nature. Hence, keeping in view the significance of nanotechnology, the current study was conducted to develop, characterize (UV-visible spectroscopy, scanning electron microscopy, Fourier-transform infrared spectroscopy, and energy-dispersive X-ray spectroscopy), and assess the antimicrobial (antibacterial and antifungal) properties of Peganum harmala L. Extract-based Gold (Au) and Silver (Ag) nanoparticles (NPs). Characteristic absorption peaks at 420 and 540 nm revealed the formation of AgNPs and AuNPs, respectively. SEM images revealed that both silver and gold nanoparticles were oval and spherical with average size ranging from 42 to 72 and 12.6 to 35.7 nm, respectively. Similarly, FT-IR spectra revealed that the functional groups such as hydroxyl, carboxyl, and polyphenolic groups of biomolecules present in the extract are possibly responsible for reducing metallic ions and the formation of nanoparticles. Likewise, the EDX analysis confirmed the presence of silver and gold in synthesized NPs. Furthermore, the AgNPs and AuNPs showed good antibacterial and antifungal activities. The maximum antibacterial and antifungal activity was noticed for P. harmala extract against Pseudomonas aeroginosa (21 mm) and Candida albicon (18 mm), respectively. Whereas, the maximum antibacterial and antifungal activities of synthesized AgNPs were observed against Salmonella typhi (25 mm) and Penicillium notatum (36 mm), respectively. Moreover, in the case of AuNPs, the highest antibacterial and antifungal activity of synthesized AuNPs was noticed against Escherichia coli (25 mm) and C. albicon (31 mm), respectively. Findings of this study revealed that P. harmala extract and biosynthesized NPs (silver and gold) possessed significant antibacterial and antifungal properties against different bacterial (Bacillus subtilis, Staphylococcus aureus, E. coli, P. aeroginosa, and S. typhi) and fungal (C. albicans, Aspergillus Niger, and P. notatum) strains. Further studies must be carried out to assess the probable mechanism of action associated with these antimicrobial properties.
RESUMEN
Peganum harmala L. is a perennial herbaceous plant that plays critical roles in protecting the ecological environment in arid, semi-arid, and desert areas. Although the seed germination characteristics of P. harmala in response to environmental factors (i.e., drought, temperature, and salt) have been investigated, the response mechanism of seed germination to drought conditions has not yet been revealed. In this study, the changes in the physiological characteristics and transcriptional profiles in seed germination were examined under different polyethylene glycol (PEG) concentrations (0-25%). The results show that the seed germination rate was significantly inhibited with an increase in the PEG concentration. Totals of 3726 and 10,481 differentially expressed genes (DEGs) were, respectively, generated at 5% and 25% PEG vs. the control (C), with 1642 co-expressed DEGs, such as drought stress (15), stress response (175), and primary metabolism (261). The relative expression levels (RELs) of the key genes regulating seed germination in response to drought stress were in accordance with the physiological changes. These findings will pave the way to increase the seed germination rate of P. harmala in drought conditions.
RESUMEN
Peganum harmala has been extensively employed in Algerian traditional medicine practices. This study aimed to explore the impact of n-butanol (n-BuOH) extract sourced from Peganum harmala seeds on cell proliferation, cell migration, and angiogenesis inhibition. Cytotoxic potential of n-BuOH extract was evaluated using MTT (3-(4,5-dimethylthiazol-2-yl) 2,5 diphenyltetrazolium bromide) assay against human breast adenocarcinoma MCF-7 cells, cell migration was determined using scratch assay, and anti-angiogenic effect was evaluated through macroscopic and histological examinations conducted on chick embryo chorioallantoic membrane. Additionally, this research estimated the phytochemical profile of n-BuOH extract. Fifteen phenolic compounds were identified using Ultra-performance liquid chromatography UPLC-ESI-MS-MS analysis. In addition, the n-BuOH extract of P. harmala exhibited potent antioxidant and free radical scavenging properties. The n-BuOH extract showed potent cytotoxicity against MCF-7 cell with an IC50 value of 8.68 ± 1.58 µg/mL. Furthermore, n-BuOH extract significantly reduced migration. A strong anti-angiogenic activity was observed in the groups treated with n-BuOH extract in comparison to the negative control. Histological analysis confirmed the anti-angiogenic effect of the n-BuOH extract. This activity is probably a result of the synergistic effects produced by different polyphenolic classes.

Harmine is a naturally occurring ß-carboline alkaloid originally isolated from Peganum harmala. As a major active component, harmine exhibits a broad spectrum of pharmacological properties, particularly remarkable antitumor effects. Recent mechanistic studies have shown that harmine can inhibit cancer cell proliferation and metastasis through epithelial-to-mesenchymal transition, cell cycle regulation, angiogenesis, and the induction of tumor cell apoptosis. Furthermore, harmine reduces drug resistance when used in combination with chemotherapeutic drugs. Despite its remarkable antitumor activity, the application of harmine is limited by its poor solubility and toxic side effects, particularly neurotoxicity. Novel harmine derivatives have demonstrated strong clinical application prospects, but further validation based on drug activity, acute toxicity, and other aspects is necessary. Here, we present a review of recent research on the action mechanism of harmine in cancer treatment and the development of its derivatives, providing new insights into its potential clinical applications and strategies for mitigating its toxicity while enhancing its efficacy.
RESUMEN
Ovarian cancer is one of the most prevalent malignancies in women. Harmaline is reported to have powerful anticancer properties. We aimed to investigate the apoptotic and antimetastatic properties of harmaline in A2780 ovarian cancer cells. Cell viability, apoptosis, migration, and invasion were investigated in cells treated with harmaline. Reactive oxygen species (ROS) production, mRNA expression of apoptosis-associated genes, MMP-2, and MMP-9 were measured. Harmaline attenuated the viability of A2780 ovarian cancer cells in a dose- and time-dependent way. Furthermore, compared to NIH/3T3 mouse normal cell line (IC50 = 417 µM), the malignant A2080 cells were more sensitive to harmaline (IC50 = 300 µM after 24 h). Harmaline increased the production of ROS, raised the mRNA expression of p53 and the Bax/Bcl2 ratio. Harmaline also increased the proportion of cells in the late apoptotic and necrotic phases. MMP-2 and MMP-9's mRNA expression, gelatinase activity, and migration of A2780 cells also decreased by harmaline. These findings suggest that harmaline may have the potential to be a therapeutic drug for ovarian cancer by triggering apoptosis and suppressing invasion and migration.

This study reports the isolation of four new ß-carboline alkaloids (1-4) and six previously identified alkaloids (5-10) from the roots of Peganum harmala L. Among these compounds, 1 and 2 were characterized as rare ß-carboline-quinazoline dimers exhibiting axial chirality. Compound 3 possessed a unique 6/5/6/7 tetracyclic ring system with an azepine ring, and compound 4 was a novel annomontine ß-carboline. The structures of these compounds were elucidated by spectroscopic data and quantum mechanical calculations. The biosynthetic pathways of 1-3 were proposed. Additionally, the cytotoxicity of some isolates against four cancer cell lines (HL-60, A549, MDA-MB-231, and DU145) was evaluated. Notably, compound 4 exhibited significant cytotoxicity against HL-60, A549, and DU145 cells with IC50 values of 12.39, 12.80, and 30.65 µmol·L-1, respectively. Furthermore, compound 2 demonstrated selective cytotoxicity against HL-60 cells with an IC50 value of 17.32 µmol·L-1.

An endophytic actinomycete designated TRM65318T, was isolated from the root of Peganum harmala L. Its taxonomic status was determined using a polyphasic approach. Comparative 16S rRNA gene sequence analysis indicated that strain TRM65318T is phylogenetically most closely related to Myceligenerans salitolerans XHU 5031T (98.15â%) and Myceligenerans xiligouense DSM 15700T (97.78â%). The peptidoglycan belonged to type A4α. The polar lipids were phosphatidylinositol, phosphatidylglycerol, diphosphatidylglycerol, two unknown lipids and three glycolipids. The predominant menaquinones were MK-9(H4) and MK-9(H6) and the whole-cell sugars contained glucose, mannose and galactose. Major fatty acids were anteiso-C15â:â0, iso-C15â:â0 and C16â:â0. Strain TRM65318T had a genome size of 5881012 bp with a genome G+C content of 71.79 mol%. The average nucleotide identity and DNA-DNA hybridization values between strain TRM65318T and the most closely related species were much lower than the thresholds commonly used to define species. At the same time, differences in phenotypic and genotypic data showed that strain TRM65318T could be clearly distinguished from M. salitolerans XHU 5031T. Therefore, it is concluded that strain TRM65318T represents a novel species of the genus of Myceligenerans. The proposed name for this organism is Myceligenerans pegani sp. nov., with type strain TRM65318T (=CCTCC AA 2019057T=LMG 31679T).

Globally, there is an increase in a number of bone disorders including osteoarthritis (OA), osteomyelitis, bone cancer, and etc., which has led to a demand for bone tissue regeneration. In order to take use of the osteogenic potential of natural herbs, mesoporous bioactive glass nanoparticles (MBGNs) have the ability to deliver therapeutically active chemicals locally. MBGNs influence bioactivity and osteointegration of materials making them suitable for bone tissue engineering (BTE). In the present study, we developed Peganum Harmala (P. harmala) loaded MBGNs (PH-MBGNs) synthesized via modified Stöber process. The MBGNs were analyzed in terms of surface morphology, chemical make-up, amorphous nature, chemical interaction, pore size, and surface area before and after loading with P. harmala. A burst release of drug from PH-MBGNs was observed within 8 h immersion in phosphate buffer saline (PBS). PH-MBGNs effectively prevented Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli) from spreading. Furthermore, PH-MBGNs developed a hydroxyapatite (HA) layer in the presence of simulated body fluid (SBF) after 21 days, which confirmed the in-vitro bioactivity of MBGNs. In conclusion, PH-MBGNs synthesized in this work are potential candidate for scaffolding or a constituent in the coatings for BTE applications.
RESUMEN
Currently, the main pillars in treating breast cancer involve tumorectomy pursued by hormonal, radio, or chemotherapies. Nonetheless, these approaches exhibit severe adverse effects and might suffer from tumor recurrence. Therefore, there is a considerable demand to fabricate an innovative controlled-release nano-delivery system to be implanted after tumor surgical removal to guard against cancer recurrence. In addition, combining platinum-based drugs with phytochemicals is a promising approach to improving the anticancer activity of the chemotherapeutics against tumor cells while minimizing their systemic effects. This study designed polycaprolactone (PCL)-based electrospun nanofiber mats encapsulating nedaplatin (N) and Peganum harmala alkaloid-rich fraction (L). In addition to physicochemical characterization, including average diameters, morphological features, degradation study, thermal stability, and release kinetics study, the formulated nanofibers were assessed in terms of cytotoxicity, where they demonstrated potentiated effects and higher selectivity towards breast cancer cells. The dual-loaded nanofiber mats (N + L@PCL) demonstrated the highest antiproliferative effects against MCF-7 cells with a recorded IC50 of 3.21 µg/mL, as well as the topmost achieved selectivity index (20.45) towards cancer cells amongst all the tested agents (N, L, N@PCL, and L@PCL). This indicates that the dual-loaded nanofiber excelled at conserving the normal breast epithelial cells (MCF-10A). The combined therapy, N + L@PCL treatment, resulted in a significantly higher percent cell population in the late apoptosis and necrosis quartiles as compared to all other treatment groups (p-value of ≤0.001). Moreover, this study of cell cycle kinetics revealed potentiated effects of the dual-loaded nanofiber (N + L@PCL) at trapping more than 90% of cells in the sub-G1 phase and reducing the number of cells undergoing DNA synthesis in the S-phase by 15-fold as compared to nontreated cells; hence, causing cessation of the cell cycle and confirming the apoptosis assay results. As such, our findings suggest the potential use of the designed nanofiber mats as perfect implants to prevent tumor recurrence after tumorectomy.
RESUMEN
The study was designed to evaluate the effects of the total alkaloid extract of Algerian Peganum harmala seeds on sexual behavior and male reproductive function. After two weeks of acclimatization, the male mice were randomly divided into four groups (seven mice in each group). For 35 days, the extract was administered orally at dose levels of 6.25, 12.5, and 25 mg/kg body weight per day to the respective groups of male mice (n = 7) and normal saline daily to the control group. On day 28, sexual behavior parameters were recorded. At the end of the trial, reproductive organ weights, sperm quality, seminal fructose, and testosterone hormone levels were evaluated. The three treated groups were compared with the control using statistical variance analysis (one-way ANOVA, p < 0.05), followed by Tukey's test. The results of the groups treated with 12.5 and 6.25 mg/kg of P. harmala alkaloid revealed the MF and IF parameters to be the lowest compared to the control group (p < 0.05). However, the male mice treated with 25 mg/kg recorded the highest values. A low significant value of ML was observed in the group treated with 25 mg/kg of the total alkaloid extract of P. harmala compared to the control group (p < 0.01), while a rise was observed in the concentration group treated with 6.25 mg/kg. Regarding IL, the male mice treated with different concentrations of the total alkaloid extract of P. harmala recorded a higher time than the control group. Moreover, an increase in the gonadosomatic index was noticed in all groups compared to the control group. However, there was a significant (p < 0.01) decrease in the sperm counts of the groups treated with 12.5 mg/kg and 6.25 mg/kg. However, there was no significant difference in the motility, membrane integrity, and total antioxidant capacity of sperm cells compared to the control. The extract treatment also brought about a non-significant increase in fructose content of the seminal vesicle and serum testosterone level. The findings of this study demonstrate that the extract acts in a dose-dependent manner, and it has varying effects on the reproductive parameters of male mice.
RESUMEN
Seed germination is a crucial stage in the life cycle of annuals in arid, saline regions and is particularly vulnerable to abiotic stresses. Peganum harmala, a valuable medicinal plant, has limited research on its seed germination response to different environmental stresses in the arid, saline regions of Central Asia. To investigate this, we studied the effects of various temperature regimes (ranging from 20/5 to 35/20 °C), light exposure (12 hours light/12 hours dark and continuous dark), seven levels of polyethylene glycol (PEG-6000) concentration (ranging from 0-30%), and four types of salinity (ranging from 0-600 mmol L-1). Our findings show that photoperiod and temperature significantly influence germination. Optimal temperature range for seed germination was observed at 30/15 °C, with simulated critical and limit values of drought tolerance being highest (17.30% and 24.98%). However, higher temperatures (35/20 °C) and lower temperatures (20/5 °C) reduced the critical and limit values of drought tolerance. Additionally, the type and concentration of salinity had a significant effect on the seed germination, shoot, and root lengths of P. harmala. Regression analysis indicated that the critical values of NaCl, Na2SO4, NaHCO3, and Na2CO3 tolerance during germination were 178 mmol L-1, 101 mmol L-1, 106 mmol L-1, and 54 mmol L-1, respectively. Salinity inhibition on seed germination followed the order: NaCl < NaHCO3 < Na2SO4 < Na2CO3. Moreover, NaCl, Na2SO4, NaHCO3, and Na2CO3 significantly inhibited the growth of P. harmala seedlings in both shoots and roots. Our study demonstrates the sensitivity of P. harmala to environmental factors such as light, temperature, drought, and salinity. The study provides valuable information on the germination ecology of P. harmala under diverse ecological scenarios, which can be useful in developing efficient propagation and utilization of this medicinal plant.

RESUMEN
Extracting high-yield, high-quality DNA from plant samples is challenging due to the presence of the cell wall, pigments, and some secondary metabolites. The main CTAB method, two of its modified protocols (beta-mercaptoethanol or ammonium acetate were eliminated), the modified Murray and Thompson method, and the Gene All kit were statistically compared based on the quantity and quality of the total DNA (tDNA) extracted from fresh and dried leaves of three medicinal herbs P. harmala, T. ramosissima, and P. reptans. The suitability of the tDNAs for molecular studies was evaluated by polymerase chain reaction (PCR) of the fragments of the internal transcribed spacer (ITS) in nuclear DNA and the trnL-F region in chloroplast DNA. Some significant differences were found between the tDNAs extracted by five extraction methods. With the exception of P. harmala, where the PCR of both the ITS fragments and the trnL-F region worked successfully in all DNA samples, but only the ITS fragments, not the chloroplast trnL-F region, were amplified in the DNA samples of T. ramosissima and P. reptans. The chloroplast trnL-F region was amplified only in DNA samples extracted from fresh and dried leaves of the three studied herbs using the commercial kit. Gene All kit, the main CTAB method, and its modified protocols were the less time-consuming protocols that yielded DNA suitable for downstream PCR vis-a-vis the modified Murray and Thompson method.

RESUMEN
Plant-derived agents are powerful bio-pesticides for the eco-friendly control of mosquito vectors and other blood-sucking arthropods. The larval toxicity of beta-carboline alkaloids against the Asian tiger mosquito, Aedes albopictus (Skuse) (Diptera: Culicidae), was investigated under laboratory conditions. The total alkaloid extracts (TAEs) and beta-carboline alkaloids (harmaline, harmine, harmalol, and harman) from Peganum harmala seeds were isolated and tested in this bioassay. All alkaloids were tested either individually or as binary mixtures, using the co-toxicity coefficient (CTC) and Abbott's formula analysis. The results revealed considerable toxicity of the tested alkaloids against A. albopictus larvae. When all larval instars were exposed to the TAEs at 48 h post-treatment, the mortality of all larval instars varied in a concentration-dependent manner. The second-instar larvae were the most susceptible to different concentrations of TAEs, and the fourth-instar larvae were more tolerant to TAEs than the second-instar larvae. Especially, the third-instar larvae exposed to all alkaloids also showed that all doses resulted in an increased mortality of the third-instar larvae at 48 h post-treatment, and the toxicities of the tested alkaloids in a descending order were TAEs > harmaline > harmine > harmalol, with the LC50 values of 44.54 ± 2.56, 55.51 ± 3.01, 93.67 ± 4.53, and 117.87 ± 5.61 µg/mL at 48 h post-treatment, respectively. In addition, all compounds were also tested individually or in a 1:1 ratio (dose LC25/LC25) as binary mixtures to assess the synergistic toxicity of these binary combinations against the third-instar larvae at 24 and 48 h post-treatment, respectively. The results demonstrated that when tested as a binary mixture, all compounds (especially TAEs, harmaline, and harmine) showed their synergistic effects, exceeding the toxicity of each compound alone. Interestingly, the obtained data further revealed that the TAEs at sublethal doses (LC10 and LC25) could significantly delay the larval development and decrease the pupation and emergence rates of A. albopictus. This phenomenon could be helpful in order to develop more effective control strategies for different notorious vector mosquitoes.
RESUMEN
ETHNOPHARMACOLOGICAL RELEVANCE: Peganum harmala L. is a traditional medicinal plant used for centuries in folk medicine. It has a wide array of therapeutic attributes, which include hypoglycemic, sedative, anti-inflammatory, and antioxidant properties. The fruit decoction of this plant was claimed by Avicenna as traditional therapy for urolithiasis. Also, P. harmala seed showed a clinical reduction in kidney stone number and size in patients with urolithiasis. AIM OF THE STUDY: In light of the above-mentioned data, the anti-urolithiatic activities of the seed extracts and the major ß-carboline alkaloids of P. harmala were investigated. MATERIALS AND METHODS: Extraction, isolation, and characterization of the major alkaloids were performed using different chromatographic and spectral techniques. The in vivo anti-urolithiatic action was evaluated using ethylene glycol (EG)-induced urolithiasis in rats by studying their mitigating effects on the antioxidant machinery, serum toxicity markers (i.e. nitrogenous waste, such as blood urea nitrogen, uric acid, urea, and creatinine), minerals (such as Ca, Mg, P, and oxalate), kidney injury marker 1 (KIM-1), and urinary markers (i.e. urine pH and urine output). RESULTS: Two major alkaloids, harmine (P1) and harmalacidine HCl (P2), were isolated and in vivo evaluated alongside the different extracts. The results showed that P. harmala and its constituents/fractions significantly reduced oxidative stress at 50 mg/kg body weight, p.o., as demonstrated by increased levels of glutathione (GSH), glutathione reductase (GR), glutathione peroxidase (GPx), and catalase (CAT) in kidney homogenate as compared to the EG-treated group. Likewise, the total extract, pet. ether fraction, n-butanol fraction, and P1, P2 alleviated malondialdehyde (MDA) as compared to the EG-treated group. Serum toxicity markers like blood urea nitrogen (BUN), creatinine, uric acid, urea, kidney injury molecule-1 (Kim-1), calcium, magnesium, phosphate, and oxalate levels were decreased by total extract, pet. ether fraction, n-butanol fraction, P1, and P2 as compared to the EG-treated group. Inflammatory markers like NFκ-B and TNF-α were also downregulated in the kidney homogenate of treatment groups as compared to the EG-treated group. Moreover, urine output and urine pH were significantly increased in treatment groups as compared to the EG-treated group deciphering anti-urolithiatic property of P. harmala. Histopathological assessment by different staining patterns also supported the previous findings and indicated that treatment with P. harmala caused a gradual recovery in damaged glomeruli, medulla, interstitial spaces and tubules, and brown calculi materials as compared to the EG-treated group. CONCLUSION: The current research represents scientific evidence on the use of P. harmala and its major alkaloids as an effective therapy in the prevention and management of urolithiasis.

Fusarium oxysporum is a widely distributed soil-borne pathogenic fungus that can cause medicinal herbs and crops to wither or die, resulting in great losses and threat to public health. Due to the emergence of drug-resistance and the decline of the efficacy of antifungal pesticides, there is an urgent need for safe, environmentally friendly, and effective fungicides to control this fungus. Plant-derived natural products are such potential pesticides. Extracts from seeds of Peganum harmala have shown antifungal effects on F. oxysporum but their antifungal mechanism is unclear. In vitro antifungal experiments showed that the total alkaloids extract and all five ß-carboline alkaloids (ßCs), harmine, harmaline, harmane, harmalol, and harmol, from P. harmala seeds inhibited the growth of F. oxysporum. Among these ßCs, harmane had the best antifungal activity with IC50 of 0.050 mg/mL and MIC of 40 µg/mL. Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) results revealed that the mycelia and spores of F. oxysporum were morphologically deformed and the integrity of cell membranes was disrupted after exposure to harmane. In addition, fluorescence microscopy results suggested that harmane induced the accumulation of ROS and increased the cell death rate. Transcriptomic analysis showed that the most differentially expressed genes (DEGs) of F. oxysporum treated with harmane were enriched in catalytic activity, integral component of membrane, intrinsic component of membrane, and peroxisome, indicating that harmane inhibits F. oxysporum growth possibly through damaging cell membrane and ROS accumulation via regulating steroid biosynthesis and the peroxisome pathway. The findings provide useful insights into the molecular mechanisms of ßCs of P. harmala seeds against F. oxysporum and a reference for understanding the application of ßCs against F. oxysporum in medicinal herbs and crops.
