RESUMO

ETHNOPHARMACOLOGICAL RELEVANCE: Plants have been used for a long time in traditional medicine to treat many diseases. The genus Prangos belongs to the Apiaceae family and has various medicinal and aromatic species. Since ancient times, Prangos species have been employed extensively in traditional medicine for different purposes and are especially popular for their aphrodisiac effects. AIM OF THE REVIEW: The goal of this paper is to represent a systematic review of the species in the genus Prangos, including their botanical characteristics, uses in traditional medicine, phytochemical constituents, the composition of the essential oils produced, and the biological properties. MATERIALS AND METHODS: The articles regarding traditional uses and bioactivities of Prangos species were evaluated using electronic databases such as PubMed, Google Scholar, and ScienceDirect. Use of the World Flora Online (WFO) - The Plant List, The International Plant Names Index, the World Checklist of Vascular Plants (2024), and ChemDraw Professional helped complete this compilation. RESULTS: Phytochemical investigations have indicated that coumarins are characteristic constituents of Prangos species, especially prenylated simple coumarins and furanocoumarins, and also flavonoids, terpenoids, and phytosterols occur in this genus. In addition, the essential oils of these plants have been examined. The biological properties of the Prangos species seem worthy of further investigation. Also, some information about the toxicity of these species and their use as ingredients in food products is presented. CONCLUSIONS: This review highlights the evaluation of traditional knowledge, phytochemical profiles, biological activities, and potential uses of Prangos species as foods and spices. Many pharmacological activities have been performed related to their traditional uses, but frequently, the exact mechanism of action remains scientifically unproven. This review has compiled data on the phytochemistry, the active secondary metabolites, the biological properties, and recent advances in Prangos species.

RESUMO

Diabetes mellitus is a chronic metabolic disorder associated with biochemical, physiological, and pathological changes in the liver and characterized by some deficiencies in insulin secretion or insulin action. Prangos Lindl. species are important plants used as spice and medicine in Asian countries, including Türkiye. This study first aimed to evaluate the antidiabetic potential of the aerial parts of the 5 different Prangos species (Apiaceae) collected from various locations to discover and identify bioactive phenolic components. The results revealed that the methanolic extract of P. heyniae exhibited the highest activity against α-glucosidase inhibition compared to the other Prangos species (IC50 = 458.54 ± 5.62 µg/mL). For this reason, the active species P. heyniae (an endemic species) was subjected to UPLC-MS/MS to evaluate the possible active phenolic components. The results showed that 53 phenolic compounds were correctly screened, 21 were precisely determined by UPLC-MS/MS in P. heyniae. Therefore, it was concluded that the aerial parts of P. heyniae might have therapeutic potential for hyperglycemia due to its phenolic compounds. Moreover, quinic acid (3.66%), chlorogenic acid (2.35%), rutin (2.96%), and hesperidin (0.79%) might be potential markers of the methanolic extract of P. heyniae. In the end, this study provides comprehensive knowledge regarding the phenolic profile of P. heyniae related to antidiabetic activity for the first time in this study.

RESUMO

Anomalin is a seselin-type pyranocoumarin isolated for the first time from Angelica anomala Avé-Lal, but is also found in several other plant species, especially in Apiaceae. This lipophilic molecule possesses pharmacologically beneficial activities for human health. The major scientific databases Scopus, Web of Science, Google Scholar, and PubMed up to the end of 2021 and the combining terms anomalin, praeruptorin, isolation, structure elucidation, and biological activity were used in the research of this review. This review focuses on the sources, structural properties, and biological functions of anomalin and provides future trends in the investigation of anomalin, particularly in therapies for many common diseases such as anti-inflammatory and neurodegenerative illnesses. As a potential bioactive molecule, prospective studies on anomalin should be done through supported clinical trials. At the end, this review confirms the significant pharmacological potential of anomalin.

RESUMO

A limited number of mosses have been studied regarding antioxidant activity and enzyme inhibition effects. In the present study, the phytochemical content, antioxidant, and enzyme inhibition properties of the ether extracts from T.J.Kop.. were investigated as promising bryophyte sources. The ether extracts of P. ellipticum had the highest flavonoid content (52.41 ± 0.52, Rutin equivalent), and A. californica had the highest total phenolic content (25.84 ± 0.23, Gallic acid equivalent). While the P. ellipticum had the highest ABTS (mg TE/g extract) 6.60 ± 0.4); A. californica showed the highest metal chelating capacity (mg EDTA/g extract) with the values of 51.46 ± 0.26. In the enzyme activity tests, almost all values of the species were closed the each other, but P. ellipticum was exhibited higher tyrosinase activity (mg/KAE/g extract) with 48.64 ± 1.02. The results have indicated for the first time the potential importance of the selected mosses.

RESUMO

Benign prostatic hyperplasia (BPH) is one of the most prevalent conditions among aged men. The use of 5α-reductase inhibitors (5-ARIs) to treat BPH was linked to erectile dysfunction (ED). Many medicinal plants and secondary metabolites are used in the management of ED. Onion (Allium cepa L.) is an economically affordable vegetable with vital phytochemicals and biological functions. The study aimed to identify the beneficial effects of onion juice on dutasteride (a 5-ARI)-induced ED. Rats were divided into two groups (n = 5 per group): control and dutasteride-treated rats (0.5 mg/kg/day). Dutasteride was administered in drinking water for 12 weeks. Experiments were performed at the end of the 12th week. In vivo erectile responses were measured before and after intracavernosal injection of onion. Relaxant responses to onion juice were examined in the corpus cavernosum (CC). Acetylcholine (ACh)-, electrical field stimulation (EFS)-, sodium nitroprusside (SNP)-induced relaxation responses in CC tissues were evaluated in the absence and presence of onion juice. Total intracavernosal pressure (ICP) and ICP/ mean arterial pressure were significantly reduced in dutasteride-treated rats (1881.14 ± 249.72 mmHg, P < 0.001;0.26 ± 0.03, P < 0.01) as compared to control rats (4542.60 ± 429.19 mmHg, 0.51 ± 0.05), which was normalized after the intracavernous administration of onion (3288.60 ± 185.45 mmHg, 0.58 ± 0.04). Onion markedly induced relaxant responses in control (72.5 ± 4.7) and dutasteride-treated (66.5 ± 2.7) groups after precontraction with phenylephrine. Relaxation responses to onion were partially inhibited after precontraction with KCl (32.5 ± 3.1, P < 0.001). The relaxant responses to ACh (14.9 ± 4.2, P < 0.01) were diminished in dutasteride-treated CC) compared to control CC (59.8 ± 3.4), which was enhanced after the incubation with onion (36.6 ± 4.8). There were no differences in relaxation response to SNP among all groups. However, relaxation response to SNP was reduced in dutasteride-treated CC at 1 µM (P < 0.05) and 10 µM dosages (P < 0.001), which was partially increased after the incubation with onion at 10 µM dosage (P < 0.01). The presence of onion did not change the reduction in EFS-caused relaxation in the dutasteride-treated group. The current data suggest that red onion juice has a restorative effect on erectile function and endothelium-dependent relaxation response following the treatment of dutasteride.

RESUMO

BACKGROUND: The current study was aimed to investigate the anti-allergic activities of the Umbelliferone (UMB) against the acute Histamine and chronic Picryl chloride (PiCl)-induced allergy in mice. UMB is a coumarin derivative (isolated from Angelica decursiva) found in various parts of the plants such as flowers, roots and, stems isolated from the plants of Umbelliferae family. METHODS: The UMB (1, 10, 50 mg/kg) was administered intraperitoneally (i.p) half an h before or 2 h after the induction of allergic ear edema. The acute ear edema was induced by histamine (intradermally, i.d), while the chronic ear edema was induced by painting the PiCl (sensitized with the toluene) on the ear. The antioxidants and oxidative stress markers were assessed. The histological changes were assessed using Hematoxylin and eosin (H and E) and giemsa staining. The immunohistochemistry studies were performed to assess the expression of the nuclear factor erythroid 2-related factor 2 (Nrf2) and inducible nitric oxide synthase (iNOS). The data was analyzed using one-way ANOVA tests followed by Tukey's test with p < 0.05 was chosen as criteria for statistical significance. RESULTS: UMB treatment markedly reduced the allergic ear edema and ear weight compared to the negative control. Furthermore, the UMB attenuated the oxidative stress markers, while induced the antioxidants enzymes. Similarly, the UMB treatment significantly attenuated the serum immunoglobulin E (IgE) level. The UMB treatment markedly improved the histological parameters using H and E staining and Giemsa staining. The UMB administration induced the Nrf2 expression, while attenuated the iNOS expression. Furthermore, the computational analysis was performed to assess the interaction of the UMB with the various protein targets and to determine the mechanism of interaction with the target proteins. CONCLUSION: In conclusion, the UMB treatment significantly alleviated the allergic symptoms, attenuating the oxidative stress, improved the histological features using in vivo and computational approaches.

RESUMO

Seseli L. is an important genus of the Apiaceae family, with a large number of aromatic species. It is used in traditional medicine extensively, but there is quite limited information on their phytochemicals and biological activities. Seseli petraeum M. Bieb. grows in Northern Anatolia, and there are no phytochemical studies on this species. In the present study, we aimed to investigate the effect of the extracts of S. petraeum on A549 lung cancer cell proliferation. For this purpose, the antiproliferative effect was determined via MTT assay, and the extracts obtained from the root of S. petraeum showed a significant inhibitory effect on cell proliferation. The hexane extract of the root exhibited potent inhibition on A549 cancer cell growth at the 24th hour with 3.432 mg/mL IC50 value. The results also showed that the hexane extract had displayed cytotoxic effect through an arrest at the G0/G1 phase of the cell cycle and induced apoptosis as well as DNA damage of A549 cells. Consequently, this study demonstrated the antiproliferative potential of the extracts from S. petraeum, especially hexane extract from the roots. Further studies are required to identify the mechanisms underlying these effects.

RESUMO

Diabetic men are at a higher risk of erectile dysfunction (ED). A tropical plant, clove (Syn. Eugenia caryophyllata, Caryophyllus aromaticus L., Syzygium aromaticum (L.) Merr. & L.M. Perry) from the Myrtaceae family has displayed aphrodisiac activity. The present research aimed to investigate the impacts of clove essential oil (CEO) and the ingredient of CEO, eugenol (E) on ED in diabetic rats. We divided Sprague-Dawley rats into control and diabetic groups. Erectile function was evaluated before and after CEO and E intracavernosal injection. CEO- and E-induced relaxation responses were investigated in isolated corpus cavernosum (CC) using various inhibitors. The intracavernous administration of CEO and E restored erectile responses in diabetic rats. CEO and E induced remarkable relaxation in all groups. CEO- and E-induced relaxation responses were partially inhibited after pre-contraction with KCl. Tetraethylammonium and glibenclamide inhibited the relaxation response to CEO. Glibenclamide inhibited maximum relaxation to E. The inhibitors of nitric oxide synthase (NOS), soluble guanylyl cyclase and nifedipine did not change CEO- and E-induced relaxation responses. The current results suggest that CEO and the major compound of the essential oil, E improved diabetes-induced ED in rats, and CEO caused CC relaxation via K+ channels independently NO signalling pathway.

RESUMO

OBJECTIVES: In the present study, the antioxidant potency of ethyl acetate (AcOEt) and methanol (MeOH) extracts from the aerial parts of Seseli L. species was investigated for the first time. MATERIALS AND METHODS: Seseli species L. such as Seseli andronakii Woronow ex Schischk., S. campestre Besser, S. corymbosum Boiss. & Heldr., S. gummiferum subsp. gummiferum Pall. ex Sm., S. hartvigii Parolly & Nordt, S. libanotis (L.) W.Koch, S. petraeum M.Bieb., S. peucedanoides (M.Bieb.) Koso-Pol., S. resinosum Freyn & Sint., and S. tortuosum L. growing in Turkey were collected and evaluated for their antioxidant capacity by using 1.1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging and lipid peroxidation (LPO) inhibition methods. RESULTS: The highest activities as a scavenger of DPPH radicals were found in the AcOEt extracts of S. peucedanoides (M.Bieb.) Koso-Pol (IC50=0.49 mg/mL), and S. libanotis (IC50=0.75 mg/mL); α-tocopherol was used as a positive control. On the other hand, in the LPO assay, the highest activities were determined in AcOEt and MeOH extracts (at 5 mg/mL) of S. tortuosum and S. libanotis (84-94%). CONCLUSION: This report gives important information about the antioxidant capacity of Seseli L. species. This research on antioxidant capacity proves that the use of some species used in Eastern Anatolia (in salads) is correct. With this screening study performed in Seseli L. species growing in Turkey, in the future, it is planned to isolate antioxidant compounds from the most active strains of Seseli L.

RESUMO

INTRODUCTION: Organic molecules that bind to cannabinoid receptors are called cannabinoids, and they have similar pharmacological properties like the plant, Cannabis sativa L. Hyphenated liquid chromatography (LC), incorporating high-performance liquid chromatography (HPLC) and ultra-performance liquid chromatography (UPLC, also known as ultrahigh-performance liquid chromatography, UHPLC), usually coupled to an ultraviolet (UV), UV-photodiode array (PDA) or mass spectrometry (MS) detector, has become a popular analytical tool for the analysis of naturally occurring cannabinoids in various matrices. OBJECTIVE: To review literature on the use of various LC-based analytical methods for the analysis of naturally occurring cannabinoids published since 2010. METHODOLOGY: A comprehensive literature search was performed utilising several databases, like Web of Knowledge, PubMed and Google Scholar, and other relevant published materials including published books. The keywords used, in various combinations, with cannabinoids being present in all combinations, in the search were Cannabis, hemp, cannabinoids, Cannabis sativa, marijuana, analysis, HPLC, UHPLC, UPLC, quantitative, qualitative and quality control. RESULTS: Since 2010, several LC methods for the analysis of naturally occurring cannabinoids have been reported. While simple HPLC-UV or HPLC-UV-PDA-based methods were common in cannabinoids analysis, HPLC-MS, HPLC-MS/MS, UPLC (or UHPLC)-UV-PDA, UPLC (or UHPLC)-MS and UPLC (or UHPLC)-MS/MS, were also used frequently. Applications of mathematical and computational models for optimisation of different protocols were observed, and pre-analyses included various environmentally friendly extraction protocols. CONCLUSIONS: LC-based analysis of naturally occurring cannabinoids has dominated the cannabinoids analysis during the last 10 years, and UPLC and UHPLC methods have been shown to be superior to conventional HPLC methods.

RESUMO

ABSTRACT Cinnamomum cassia (Cinnamon) is a well-known traditional medicine with therapeutic benefits for centuries. We evaluated the effects of cinnamon essential oil (CEO) and its main component cinnamaldehyde (CA) on human corpus cavernosum (HCC) and rat CC. The essential oil of cinnamon was analyzed for the confirmation of the oil profile. HCC specimens from patients undergoing penile prosthesis surgery (age 48-69 years) were utilized for functional studies. In addition, erectile responses in anesthetized control and diabetic rats were evaluated in vivo after intracavernosal injection of CEO and CA, and rat CC strips were placed in organ baths. After precontraction with phenylephrine (10µM), relaxant responses to CEO and CA were investigated. CA (96.9%) was found as the major component. The maximum relaxation responses to CEO and CA were 96.4±3.5% and 96.0±5.0% in HCC and 97.5±5.5% and 96.8±4.8% in rat CC, respectively. There was no difference between control and diabetic rats in relaxation responses to CEO and CA. The relaxant responses obtained with essential oil and CA were not attenuated in the presence of nitric oxide synthase (NOS) inhibitor, and soluble guanylate cyclase inhibitor (sGS) in CC. In vivo, erectile responses in diabetic rats were lower than in control rats, which was restored after intracavernosal injection of CEO and CA. CEO and CA improved erectile function and relaxation of isolated strips of rat CC and HCC by a NO/cGMP-independent mechanism. Further investigations are warranted to fully elucidate the restorative effects of CEO and CA on diabetic erectile dysfunction.

RESUMO

In the present study, the anomalin was investigated to determine the protective effects and underlying mechanism against LPS-induced acute lung injury in mice. Anomalin administration 30 min after the LPS injection, significantly attenuated the mechanical allodynia, decrease body temperature, and improved the histological changes and inhibited the infiltration of leukocytes. The anomalin treatment markedly inhibited the production of pro-inflammatory mediators such as cytokines (IL-1ß, IL-6 and TNF-α) and NO in contrast to the LPS treated groups. Similarly, the anomalin also enhanced the level of anti-oxidant enzymes such as GST, GSH, Catalase and inhibited oxidative stress marker such as MDA. In order to explore the molecular mechanism the effect of anomalin was evaluated for mitogen activated protein kinases (MAPK) in LPS-stimulated RAW264.7 cells. The anomalin treatment significantly attenuated the MAPK proteins such as ERK1/2, JNK and p38 (which is downstream signaling proteins to the MAPKKKs and MAPKKs protein) in the RAW264.7 macrophages using western blot analysis. Furthermore, the western blot analysis showed that anomalin treatment significantly inhibited the activation of the Akt proteins in the RAW264.7 macrophages. The AP-1 served as downstream target for the MAPK pathways and the blocking MAPK pathways is responsible for the inhibition of the AP-1 protein. The AP-1/DNA binding was assessed in the RAW264.7 cells using EMSA. The anomalin treatment significantly restricted the AP-1/DNA binding activity and the decrease in the AP-1/DNA binding activity might be contributed due to the upstream inhibition of the MAPKs signaling.
