[Immune mechanism of Daphnes Cortex and its processed products on CIA rats based on B7/CD28/CTLA-4 pathway].

This study investigates the effects of Daphnes Cortex and its processed products on the differentiation of Th17/Treg cells in SD rats with type Ⅱ collagen-induced arthritis(CIA).Sixty-four SD rats were randomly divided into the normal group(normal),model group(model),fried Daphne giraldii Nitsche low-dose and high-dose groups(FDGN-L group, FDGN-H group),raw D. giraldii Nitsche low-dose and high-dose groups(RDGN-L group, RDGN-H group),daphnetin group(DAPH group),and tripterygium glycosides group(GTW group).Except for the normal group, the CIA model was immunized on the seventh day after the first immunization, and was gavaged for 28 days after the second immunization.After sampling, the inflammation of articular synovial membrane in CIA rats was observed by hematoxylin-eosin(HE)staining; the levels of transforming growth factor-ß(TGF-ß),interferon-γ(IFN-γ),interleukin(IL)-2,IL-4,and IL-10 in serum were detected by enzyme-linked immunosorbent assay(ELISA); real-time reverse transcription-PCR(qRT-PCR)and Western blot were used to detect the mRNA and protein expressions of cluster of differentiation(CD) 80(B7-1),CD 86(B7-2),CD28,and cytotoxic T lymphocyte-associated antigen 4(CTLA-4)in the synovial membrane of rats; flow cytometry was used to detect the proportion of Th17 and Treg cells in the synovial membrane of rats.The results showed that compared with the normal group, the joint synovial inflammation of rats in the model group was significantly aggravated, the arthritis index was significantly increased, and the immune organ index was increased(P<0.01).Compared with the model group, each drug administration group could improve the joint inflammation of rats to varying degrees, reduce the arthritis index, inhibit synovial hyperplasia, and reduce the immune organ index; compared with the model group, the serum levels of IL-2 and IFN-γ in each drug administration group were significantly decreased(P<0.01),TGF-ß,IL-4,and IL-10 were significantly increased(P<0.01),the mRNA and protein expressions of B7-1 and CTLA-4 in the synovial membrane were significantly increased(P<0.01),and the proportion of Th17 cells and Treg cells in the joint tissue was significantly decreased(P<0.01).In conclusion, Daphnes Cortex inhibits the expression of Th17 cells in CIA rats and promotes the expression of Treg cells by regulating the B7/CD28/CTLA-4 pathway and the balance of Th17/Treg, thereby treating rheumatoid arthritis.

Daphnetin induces ferroptosis in ovarian cancer by inhibiting NAD(P)H:Quinone oxidoreductase 1 (NQO1).

BACKGROUND: Ferroptosis, an emerging nonapoptotic, modulated cell death process characterized by iron accumulation and subsequent lipid peroxidation, has been intimately implicated in the development and progression of ovarian cancer (OC). Daphnetin (Daph), a natural product isolated from Daphne Korean Nakai, exhibits anticancer efficacy against various solid tumors. However, the specific role and potential mechanism underlying Daph-mediated modulation of ferroptosis in OC cells remain elusive. PURPOSE: This study aims to analyze the proferroptotic impacts of Daph on OC cells and to further explore the underlying mechanisms involved. STUDY DESIGN AND METHODS: We used CCK-8, wound healing and Transwell assays to assess whether Daph can inhibit the proliferation and migration of OC cells. Additionally, transmission electron microscopy (TEM), iron measurement, reactive oxygen species (ROS) analysis, lipid peroxidation assays, qRT-PCR and western blotting were utilized to evaluate the impact of Daph on ferroptosis and elucidate the potential underlying mechanism. Furthermore, RNA sequencing analysis, molecular docking analysis, cellular thermal shift assays (CETSAs) and NQO1 activity assays were used to predict and validate the binding and mechanistic interactions between Daph and NQO1. Subcutaneous tumorigenesis models were utilized to examine the effectiveness of Daph (and/or cisplatin) in vivo. RESULTS: Daph exerted antitumor effects by inducing the death and suppressing the migration of A2780 and SKOV3 cells. Further, Daph induced ferroptosis in OC cells, as evidenced by the accumulation of intracellular ferrous iron (Fe2+), ROS and lipid peroxides, as well as the decreases in the glutathione/oxidized glutathione disulfide (GSH/GSSG) ratio and the expression of ferroptosis indicators (SLC7A11 and GPX4). RNA sequencing and molecular docking analyses revealed that the direct interaction between NQO1 and Daph reduced both the activity and expression of NQO1. Importantly, NQO1 overexpression effectively alleviated the effects of Daph on proliferation, migration, and ferroptosis in vitro and in vivo. Interestingly, we also found that combination treatment with Daph, a negative regulator of NQO1, and cisplatin synergistically induced cytotoxicity in OC cells. CONCLUSION: Our findings are the firstly demonstrated that Daph acts as a novel ferroptosis inducer in OC cells by specifically targeting NQO1 and is thus a promising candidate agent for OC treatment.

Daphnetin alleviates allergic airway inflammation by inhibiting T-cell activation and subsequent JAK/STAT6 signaling.

Allergic asthma is a major health burden on society as a chronic respiratory disease characterized by inflammation and muscle tightening around the airways in response to inhaled allergens. Daphne kiusiana Miquel is a medicinal plant that can suppress allergic airway inflammation; however, its specific molecular mechanisms of action are unclear. In this study, we aimed to elucidate the mechanisms by which D. kiusiana inhibits allergic airway inflammation. We evaluated the anti-inflammatory effects of the ethyl acetate (EA) fraction of D. kiusiana and its major compound, daphnetin, on murine T lymphocyte EL4 cells stimulated with phorbol 12-myristate 13-acetate and ionomycin in vitro and on asthmatic mice stimulated with ovalbumin in vivo. The EA fraction and daphnetin inhibited T-helper type 2 (Th2) cytokine secretion, serum immunoglobulin E production, mucus secretion, and inflammatory cell recruitment in vivo. In vitro, daphnetin suppressed intracellular Ca2+ mobilization (a critical regulator of nuclear factor of activated T cells) and functions of the activator protein 1 transcription factor to reduce interleukin (IL)-4 and IL-13 expression. Daphnetin effectively suppressed the IL-4/-13-induced activation of Janus kinase (JAK)/signal transducer and activator of transcription 6 (STAT6) signaling in vitro and in vivo, thereby inhibiting the expression of GATA3 and PDEF, two STAT6-target genes responsible for producing Th2 cytokines and mucins. These findings indicate that daphnetin suppresses allergic airway inflammation by stabilizing intracellular Ca2+ levels and subsequently inactivating the JAK/STAT6/GATA3/PDEF pathway, suggesting that daphnetin is a promising alternative to existing asthma treatments.

Environmental heterogeneity structures root-associated fungal communities in Daphne arbuscula (Thymelaeaceae), a shrub adapted to extreme rocky habitats.

Rocky habitats, globally distributed ecosystems, harbour diverse biota, including numerous endemic and endangered species. Vascular plants thriving in these environments face challenging abiotic conditions, requiring diverse morphological and physiological adaptations. Their engagement with the surrounding microbiomes is, however, equally vital for their adaptation, fitness, and long-term survival. Nevertheless, there remains a lack of understanding surrounding this complex interplay within this fascinating biotic ecosystem. Using microscopic observations and metabarcoding analyses, we examined the fungal abundance and diversity in the root system of the rock-dwelling West Carpathian endemic shrub, Daphne arbuscula (Thymelaeaceae). We explored the diversification of root-associated fungal communities in relation to microclimatic variations across the studied sites. We revealed extensive colonization of the Daphne roots by diverse taxonomic fungal groups attributed to different ecological guilds, predominantly plant pathogens, dark septate endophytes (DSE), and arbuscular mycorrhizal fungi (AMF). Notably, differences in taxonomic composition and ecological guilds emerged between colder and warmer microenvironments. Apart from omnipresent AMF, warmer sites exhibited a prevalence of plant pathogens, while colder sites were characterized by a dominance of DSE. This mycobiome diversification, most likely triggered by the environment, suggests that D. arbuscula populations in warmer areas may be more vulnerable to fungal diseases, particularly in the context of global climate change.

The aim is to provide a theoretical basis for further study of D. genkwa and its potential new clinical applications.

Daphnane diterpenoid orthoesters with an odd-numbered aliphatic side chain from Daphne pedunculata.

Daphnane diterpenoids were recognized for their extensive range of potent biological activities. In the present study, phytochemical investigation including LC-MS/MS analysis resulted in the identification of five daphnane diterpenoid orthoesters (1-5). Among the five daphnane diterpenoids, two previously unreported compounds, daphnepedunins I and J (2 and 4) were isolated from Daphne pedunculata. The structure of new compounds was elucidated with extensive physicochemical and spectroscopic analyses. Their structure was characterized by the presence of an unusual odd-numbered aliphatic chain connected to an orthoester. The isolated compounds were evaluated for their anti-HIV activity against HIV-1 infection of MT4 cells, and the results indicated that compound 1 showed the most potent anti-HIV activity with an IC50 value of 0.82 nM.

Unravelling some factors affecting sexual reproduction in rock-specialist shrub: Insight from an endemic Daphne arbuscula (Thymelaeaceae).

The role of endemic species in global biodiversity is pivotal, and understanding their biology and ecology is imperative for their fitness and long-term survival, particularly in the face of ongoing climatic oscillations. Our primary goal was to investigate the sexual reproduction level of the endangered Western Carpathian endemic Daphne arbuscula (Thymelaeaceae), which inhabits extreme rocky habitats, and to comprehend the influence of specific factors on its reproductive success. We conducted the research across four populations, varying in size and environmental conditions. Over two years, we monitored flower and fruit production, analyzed genetic variability within and among populations, and studied pollination mechanisms. Daphne arbuscula proved to be strictly self-incompatible, with significant variations in flower and fruit production among populations and seasons. The average fruit production percentage consistently remained below 50% across populations, indicating challenges in sexual reproduction. Cold and harsh weather during the reproductive phase had a substantial negative impact on sexual reproduction efficacy, leading to decreased fruit production. Nevertheless, several individuals in sheltered microhabitats displayed significantly higher fruit production, ranging from 60% to 83%, emphasizing the critical role of microhabitat heterogeneity in sustaining sexual reproduction in this species. We found no pronounced differences in genetic diversity within or among populations, suggesting that genetic factors may not critically influence the reproductive success of this endemic species. The implications of our findings might be of paramount importance for the long-term survival of D. arbuscula and offer valuable insights for the development of effective conservation strategies for this species.

New daphnane diterpenoidal 1,3,4-oxdiazole derivatives as potential anti-hepatoma agents: Synthesis, biological evaluation and molecular modeling studies.

Hepatocellular carcinoma (HCC) is a major challenge for human healthy. Daphnane-type diterpenes have attracted increasingly attention due to remarkable pharmaceutical potential including anti-HCC activity. To further develop this class of compounds as inhibitors of HCC, the daphnane diterpenoids 12-O-debenzoyl-Yuanhuacine (YHC) and 12-hydroxydaphnetoxin (YHE) were prepared by a standard chemical transformation from dried flower buds of the Daphne genkwa plant. Subsequently, 22 daphnane diterpenoidal 1,3,4-oxdiazole derivatives were rationally designed and synthesized based on YHC and YHE. The assessment of the target compound's anti-hepatocellular carcinoma activity revealed that YHC1 exhibited comparable activity to sorafenib in the Hep3B cell line, while demonstrating higher selectivity. The mechanistic investigation demonstrates that compound YHC1 induces cell cycle arrest at the G0/G1 phase, cellular senescence, apoptosis, and elevates cellular reactive oxygen species levels. Moreover, molecular docking and CETSA results confirm the interaction between YHC1 and YAP1 as well as TEAD1. Co-IP experiments further validated that YHC1 can effectively inhibit the binding of YAP1 and TEAD1. In conclusion, YHC1 selectively targets YAP1 and TEAD1, exhibiting its anti-hepatocellular carcinoma effects through the inhibition of their interaction.

Don. Their planar structures were elucidated by extensive spectroscopic analyses. The configurations were established with the assistance of quantum chemical calculations, together with the Custom DP4+ method. The inhibitory potentials of all isolates against acetylcholinesterase were evaluated.

In addition, cumulative concentrations of DGAE induced vasodilatation through receptoractivated calcium channels (ROCCs) without affecting ACE-2. CONCLUSION: The aqueous extract of Daphne gnidium exhibits antihypertensive activity and induces vasodilatation via the inhibition of Ca2+ entry.

Daphnepedunins G and H, anti-HIV macrocyclic 3,4-seco-daphnane orthoesters from Daphne pedunculata.

Daphnepedunins G (1) and H (2) with unusual macrocyclic 3,4-seco-daphnane orthoester structure were isolated from Daphne pedunculata. Their structures were determined by physicochemical and spectroscopic analyses combined with synthetic methods, including methyl esterification, derivatization reaction using a chiral anisotropic agent, and biomimetic conversion. Compounds 1 and 2 along with their methyl esters 1a and 2a were evaluated for anti-HIV activity, among which 1a and 2a exhibited potent activity with IC50 values of 1.08 and 1.17 µM, respectively.

Six undescribed guaianolide-type sesquiterpenes from the aerial parts of Daphne penicillata.

Six undescribed guaianolide sesquiterpenes (1-6) were obtained from the aerial parts of Daphne penicillata. Their structures and absolute configuration were elucidated by HRESIMS, NMR analyses, ECD calculations and single-crystal X-ray diffraction analysis. Structurally, all compounds possess the typical 5,7-fused system of 8,12-guaianolides and this guaianolide-type was first reported to be isolated from Daphne penicillata. All compounds (1-6) were evaluated for anti-inflammatory and cytotoxic activity. Among them, compounds 1 and 5 showed moderate inhibitory effects on LPS-induced NO production in BV2 cells and 4 displayed potential inhibition against Hep3B cells with an IC50 value of 7.33 µM.

Structurally diverse rearranged sesquiterpenoids, including a pair of rare tautomers, from the aerial parts of Daphne penicillata.

Eight structurally diverse rearranged sesquiterpenoids, including seven undescribed sesquiterpenoids (1a/1b and 3-8) were obtained from the aerial parts of Daphne penicillata. 1a/1b, 3, 5 and 6 possess rare rearranged guaiane skeletons and 4 represents the first example of rearranged carotene sesquiterpenoids. Their structures and absolute configurations were determined by extensive spectroscopic analyses, NMR and ECD calculations. Interestingly, 1a and 1b were a pair of magical interconverting epimers that may interconvert by retro-aldol condensation. The mechanism of interconversion has been demonstrated indirectly by 9-OH derivatization of 1a/1b and a hypothetical biogenetic pathway was proposed. All compounds were evaluated for anti-inflammatory and cytotoxic activities. Among them, 1a/1b and 2 exhibited potential inhibitory activities on the production of NO against LPS-induced BV2 microglial cells.

Night and day: Contributions of diurnal and nocturnal visitors to pollen dispersal, paternity diversity, and fruit set in an early-blooming shrub, Daphne jezoensis.

PREMISE: Under uncertain pollinator visit conditions, plants often exhibit long flowering periods and generalized pollination systems. Flowering of the gynodioecious shrub Daphne jezoensis occurs in early spring in cool temperate forests. Pollination by nocturnal moths is expected, given the species' tubular-shaped flowers with sweet fragrance and nectar. However, the effectiveness of nocturnal moths under cool conditions is unknown. We evaluated the relative importance of diurnal and nocturnal visitors as pollinators in early spring. METHODS: We investigated flowering duration, flower visitors, and floral scents in a natural population. We experimentally exposed flowers to visitors only during daytime or nighttime using bagging treatments and evaluated the contributions of diurnal and nocturnal insects to fruit set, pollen dispersal distance, and paternity diversity using 16 microsatellite markers. RESULTS: Female flowers lasted ~3 wk, which was ~8 d longer than the flowering period of hermaphrodites. Various insects, including Coleoptera, Diptera, Hymenoptera, and Lepidoptera, visited the flowers during both daytime and nighttime. Flowers emitted volatiles, such as lilac aldehyde isomers and ß-ocimene, which are known to attract moths. Fruit-set rate in the night-open treatment was similar to or higher than that in the day-open treatment. However, pollen dispersal distance in the night-open treatment was shorter than that in the day-open treatment. Paternity diversity was similar in day-open and night-open treatments. CONCLUSIONS: Early-blooming plants ensure pollen receipt and dispersal by having a long flowering period and using both diurnal and nocturnal flower visitors, suggesting the importance of a generalized pollination system under uncertain pollinator visit conditions.

Meroterpenoids from Daphne genkwa shows promising in vitro antitumor activity via inhibiting PI3K/Akt/mTOR signaling pathway in A549 cells.

Phytochemical investigation into the leaves and branches of Daphne genkwa afforded 25 meroterpenoids (1-16) including nine pairs of enantiomers (1a/1b-8a/8b and 12a/12b), among which 20 compounds have been reported in the present work for the first time. The structures with absolute configurations of the new molecules (excluding 10-13) were established via comprehensive spectroscopic analyses especially electronic circular dichroism (ECD) and Mosher's methods. A preliminary in vitro cell viability assay revealed remarkable cytotoxicities of selective compounds against A549 (lung), Hela (cervical), MDA-MB231 (breast) and MCF-7 (breast) cancer cells, and compound 8a showed the best inhibitory activity with IC50 values in the range of 3.12-4.67 µM toward the four cell lines. Subsequent in vitro antitumor evaluation of 8a disclosed that it could inhibit the proliferation and metastasis, as well as induce significant apoptosis and cycle arrest, of A549 cells. Further mechanistic investigations revealed that 8a could exert its antitumor activity via inhibiting the PI3K/Akt/mTOR signaling pathway.

This study evaluated several secondary metabolites, essential oils (EOs) compositions, and antioxidant activity in four medicinal plants that originated in Isfahan rangelands. The species were Astragalus verus, Astragalus adscendens, Daphne mucronata, and Phlomis olivieri. Thirty-two genotypes of these species were evaluated for different biochemical traits. Based on the evaluation of EOs compounds, GC/MS analysis revealed the total number of identified compounds. These compounds were 25, 22, 12, and 22 for A. adscendens, A. verus, D. mucronata, and P. olivieri, respectively. The dominant compounds were phthalate (59.88 %) in A. adscendens, phytol (38.02 %) in A. verus, hexanoic acid (32.05 %) in D. mucronata and ß-cubebene (30.94 %) in P. olivieri. Phytochemical analysis showed that D. mucronata, A. adscendens, and P. olivieri had the highest total phenolics content (TPC) (18.24 mg gallic acid equivalent/g dry weight), total flavonoids content (5.57 mg QE/g DW), and total anthocyanins content (0.23 mg/g DW), respectively. The highest total chlorophyll (0.27 mg/g DW), total carotenoids (0.03 mg/g DW), and antioxidant activity (71.36 %) were observed in A. adscendens, A. adscendens and A. verus, respectively. Among all genotypes, the highest TPC (20.1 mg GAE/g DW) was observed in genotype 5 of D. mucronata. This study provided new information on the chemical compounds within the distribution range of these ecologically dominant rangeland species in Isfahan province, Iran. The data revealed that superior genotypes from these species are rich in natural antioxidants and bioactive compounds. Thus, they can be used in ethno pharmacological fields, food, and industrial applications.

Identification of Daphne genkwa and Its Vinegar-Processed Products by Ultraperformance Liquid Chromatography-Quadrupole Time-of-Flight Mass Spectrometry and Chemometrics.

Crude herbs of Daphne genkwa (CHDG) are often used in traditional Chinese medicine to treat scabies baldness, carbuncles, and chilblain owing to their significant purgation and curative effects. The most common technique for processing DG involves the use of vinegar to reduce the toxicity of CHDG and enhance its clinical efficacy. Vinegar-processed DG (VPDG) is used as an internal medicine to treat chest and abdominal water accumulation, phlegm accumulation, asthma, and constipation, among other diseases. In this study, the changes in the chemical composition of CHDG after vinegar processing and the inner components of the changed curative effects were elucidated using optimized ultrahigh-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF-MS). Untargeted metabolomics, based on multivariate statistical analyses, was also used to profile differences between CHDG and VPDG. Eight marker compounds were identified using orthogonal partial least-squares discrimination analysis, which indicated significant differences between CHDG and VPDG. The concentrations of apigenin-7-O-ß-d-methylglucuronate and hydroxygenkwanin were considerably higher in VPDG than those in CHDG, whereas the amounts of caffeic acid, quercetin, tiliroside, naringenin, genkwanines O, and orthobenzoate 2 were significantly lower. The obtained results can indicate the transformation mechanisms of certain changed compounds. To the best of our knowledge, this study is the first to employ mass spectrometry to detect the marker components of CHDG and VPDG.

Of these compounds, compound 3 exhibited significant antioxidant activities.

Complete genome sequence of daphne virus 1, a novel cytorhabdovirus infecting Daphne odora.

A novel cytorhabdovirus was identified in Daphne odora in South Korea using high-throughput sequencing. The virus, tentatively named "daphne virus 1" (DV1), has a full-length genome sequence of 13,206 nucleotides with a genome organization comparable to that of unsegmented plant rhabdoviruses and contains seven antisense putative genes in the order 3'-leader-N-P'-P-P3-M-G-L-5'-trailer. The coding region of the genome is flanked by a 3' leader and a 5' trailer sequence, 261 and 151 nucleotides long, respectively. The DV1 genome shares 33.74%-57.44% nucleotide sequence identity with other cytorhabdoviruses. The DV1-encoded proteins share the highest amino acid sequence identity with homologues from Asclepias syriaca virus 1. Phylogenetic analysis showed that DV1 clustered with representative cytorhabdoviruses. We propose classifying DV1 in a new species within the genus Cytorhabdovirus, family Rhabdoviridae.

Exploring the hub genes and mechanisms of Daphne altaica treating esophageal squamous cell carcinoma based on network pharmacology and bioinformatics analysis.

PURPOSE: Esophageal squamous cell carcinoma (ESCC), is a frequent digestive tract malignant carcinoma with a high fatality rate. Daphne altaica (D. altaica), a medicinal plant that is frequently employed in Kazakh traditional medicine, and which has traditionally been used to cure cancer and respiratory conditions, but research on the mechanism is lacking. Therefore, we examined and verified the hub genes and mechanism of D. altaica treating ESCC. METHODS: Active compounds and targets of D. altaica were screened by databases such as TCMSP, and ESCC targets were screened by databases such as GeneCards and constructed the compound-target network and PPI network. Meantime, data sets between tissues and adjacent non-cancerous tissues from GEO database (GSE100942, GPL570) were analyzed to obtain DEGs using the limma package in R. Hub genes were validated using data from the Kaplan-Meier plotter database, TIMER2.0 and GEPIA2 databases. Finally, AutoDock software was used to predict the binding sites through molecular docking. RESULTS: In total, 830 compound targets were obtained from TCMSP and other databases. In addition, 17,710 disease targets were acquired based on GeneCards and other databases. In addition, we constructed the compound-target network and PPI network. Then, 127 DEGs were observed (82 up-regulated and 45 down-regulated genes). Hub genes were screened including TOP2A, NUF2, CDKN2A, BCHE, and NEK2, and had been validated with the help of several publicly available databases. Finally, molecular docking results showed more stable binding between five hub genes and active compounds. CONCLUSIONS: In the present study, five hub genes were screened and validated, and potential mechanisms of action were predicted, which could provide a theoretical understanding of the treatment of ESCC with D. altaica.
