(NLM (Medline), 2022) Lal Chand Pal; Shivankar Agrawal; Arti Gautam; Jayhind Kumar Chauhan; Chandana Venkateswara Rao
Anogeissus acuminata is used to treat wounds, diarrhoea, dysentery, and skin ailments. However, its hepatoprotective effect against ethanol-induced liver damage is yet to be reported. The phenolic-enriched ethyl acetate fraction of Anogeissus acuminata (AAE) was evaluated for hepatoprotective activity against ethanol-induced liver toxicity in rats. The intoxicated animals were treated with a phenolic-rich fraction of Anogeissus acuminata (AAE) (100 and 200 mg/kg) and silymarin (100 mg/kg). The antioxidant activity of AAE was analysed. Biochemical markers (ALT, AST, ALP, GGT, and TBL) for liver injury in ethanol-administered animals resulted in higher levels of key serum biochemical injury markers, as evidenced by increased levels of ALT (127.24 ± 3.95), AST (189.54 ± 7.56), ALP (263.88 ± 12.96), GGT (91.65 ± 3.96), and TBL (2.85 ± 0.12) compared to Group I ALT (38.67 ± 3.84), AST (64.45 ± 5.97), GGT (38.67 ± 3.84), and TBL (0.53 ± 064) (p < 0.05). AAE administration decreased serum biochemical liver injury markers as manifested in Group III animals' ALT (79.56 ± 5.16), AST (151.76 ± 6.16), ALP (184.67 ± 10.12), GGT (68.24 ± 4.05), TBL (1.66 ± 0.082) (p < 0.05), and Group IV ALT (55.54 ± 4.35), AST (78.79 ± 4.88), ALP (81.96 ± 9.43), GGT (47.32 ± 2.95), TBL (0.74 ± 0.075) (p < 0.05). Group IV exhibited the most significant reduction in serum biochemical markers as compared to Group III (p < 0.05) and close to silymarin-treated Group V ALT (44.42 ± 3.15), AST (74.45 ± 5.75), ALP (67.32 ± 9.14), GGT (42.43 ± 2.54), TBL (0.634 ± 0.077). Gene expression indices and histoarchitecture were evaluated to demonstrate the potential of AAE. The bioactive fraction of Anogeissus acuminata was rich in phenolics and flavonoid content. GC-MS analysis identified gallic acid, palmitic acid, cis-10-heptadecenoic acid, 9-octadecenoic acid, epigallocatechin, 2,5-dihydroxyacetophenone, and catechin. Oral administration of AAE (100 and 200 mg/kg) lowered the elevated levels of the biochemical markers and interleukin, and enhanced the level of enzymatic antioxidant. It also downregulated the expression level of proapoptotic genes and upregulated the expression level of the antiapoptotic gene along with improved liver histopathology.

(Nature Research, 2024) Jayhind Kumar Chauhan; Pawan K. Dubey; Sangeeta Rai; Anima Tripathi
Endometriosis is a common condition that affects 5% to 10% of women during their reproductive years, although the aetiology and pathophysiology are still unknown. This study aimed to create an endometriosis model in rats to investigate the efficacy of natural and synthetic medications in treating endometriosis. An in vivo endometriotic model was established using a surgical induction method and the endocrine-disrupting drug diethylstilbestrol (DES). In brief, the experiment is categorised into three different groups. Each group contains five rats. The first group had no surgery, while in the in the second group of rats (n = 5), two small tissue grafts were fixed at the right and left walls of the abdomen. But in the in the third group of rats (n = 5), two small pieces of tissue have been grafted on the right and left abdomen walls by surgically along with DES treatments. Noninvasive photoacoustic imaging (PAI) was employed in the study to measure factors such as haemoglobin levels, oxygen saturation, and the size of endometriotic lesions. Histopathological analysis was carried out utilising staining techniques such as Hematoxylin and Eosin, Masson's Trichrome, and Periodic Acid Schiff, as well as immunohistochemistry with marker antibodies. Molecular markers in uterine tissue were examined using Western blots and real-time PCR. The developed endometriosis rat model showed a significant increase in the expression of anti-apoptotic Bcl-2, angiogenic marker VEGF and pro-inflammatory (COX-2 and IL-6) protein markers. In contrast to the control group, the treatment group had considerably lower Caspase-3 expression levels. Photoacoustic imaging (PAI) data demonstrated a constant increase in lesion size, as well as a decrease in oxygen saturation levels. The findings suggest that the in vivo endometriosis rat model may accurately assess the efficacy of natural or synthetic endometriosis treatments. This model may help in the improvement of disease understanding and the development of targeted therapeutic drugs. © The Author(s) 2024.

(Springer Science and Business Media Deutschland GmbH, 2023) Safiya Ayesha; Alka Sharma; Jayhind Kumar Chauhan; Vivek Pandey; Garima Tripathi; Pawan K. Dubey; Anima Tripathi
Endometriosis is a chronic and complex endocrine disorder that affects women of reproductive age. This syndrome is benign and is characterized by a combination of ovarian dysfunction and estrogen dependency symptoms, as well as pain and infertility. The most commonly stated symptoms include dysmenorrhea, significant dyspareunia, dyschezia, and dysuria. It is a severe public health issue. The prevalence rate is quite high and continues to rise on a daily basis. Starting with its diagnosis, pathophysiology, repercussions, and treatment options, there are numerous areas of disagreement. This study aims to provide an overview of the development of endometriosis diagnosis, symptoms, risk factors, etiology, medicinal plants, phytochemicals, and treatment, with a focus on research and the creation of novel therapeutic strategies. We conclude by making predictions and recommendations for the future of endometriosis-related research and prospective therapy approaches.

(Springer, 2025) Jayhind Kumar Chauhan; Pradeep Vijay Dinesh Kumar; Pawan Kumar Dubey; Anima Tripathi
Putranjiva roxburghii is an important medicinal plant utilized for remedy of female reproductive ailments. Its seed extract is being used as a uterine health booster due to the presence of several pharmaceutically important phytochemicals. However, the presence of phytochemicals in its leaf is still unexplored. The present study was designed to explore phytochemical finger printing and assessment of anti-oxidant and anti-inflammatory activities of hydroalcoholic leaf extract of P. roxburghii (HALEPR). The qualitative, quantitative phytochemical of flavonoid, phenol and HRA-MS analysis of HALEPR carried out along with antioxidant and in vitro membrane stabilization and protein denaturation assay of anti-inflammatory activity were have been analyzed. Results of qualitative phytochemical screening of HALEPR denotes the existence of phenol, flavonoids, alkaloids, coumarins, steroids, saponins, tannins, anthroquinone and carbohydrates. The quantitative phytochemical of flavonoid and phenol was done which revealed the presents of total phenol and flavonoid. High resolution accurate-mass spectrometry (HRA-MS) study was also done for the identification of bioactive compounds from the HALEPR, which showed the presence of various phytochemicals such as luteolin 3′- (3″-acetylglucuronide), luteolin 4′-methyl ether 7-glucoside, quercetin-3β-D-glucoside, 8-hydroxyluteolin 4′-methyl ether 8-glucuronide, quercetin 3-xylosyl- (1- > 2) -rha mnosyl- (1- > 6) –glucoside, quercetin-3β-D-glucoside, myricetin 3- (3-6-diacetylglucosyl) - (1- > 4) - (2″,3″-diacetylrhamnoside), apigetrin, isorhamnetin, catechin 7,3′-Di-O-β-D glucopyranoside, luteolin 7-methylglucuronide, apigenin-8-C-α -l-arabinopyranoside, naringenin 7- O-β-D-glucoside 6″-acetate,ohobanin, shogaol, ginkgetin and amoritin. The HELPER is shown to have the presence of anti-oxidant and anti-inflammatory activities as demonstrated by DPPH (1, 1-diphenyl,2-picrylhydrazyl) and membrane lysis assays. Our findings reveal the presence of phytochemicals in HALEPR that have significant antioxidant and anti-inflammatory activity. The bioactivities were identified using chemical characterization like HRA/MS and biological assessments like anti-inflammatory and antioxidant assays. Future research may focus on isolating specific molecules, conducting in vivo tests, and creating HALEPR-based formulations for clinical application as anti-inflammatory drugs. © The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature 2025.

Studies provide notable evidence that oxidative stress (OS) mediated reactive oxygen species (ROS) disturb reproductive health. We have shown in our previous publication that exposure of Di-(2-ethylhexyl) phthalate (DEHP), induces OS mediated ROS generation which inhibits steroid synthesis. In the present study, we demonstrated the ameliorative/protective effects of one of the steroidal saponins, i.e., Shatavarin-IV, isolated from the roots of Asparagus racemosus against DEHP induced OS in rat granulosa cells. Granulosa cells were exposed with DEHP alone (400 μM), Shatavarin-IV alone (8 μg/ml), and a combination of DEHP + Shatavarin-IV (400 μM + 8 μg/ml) in vitro for 24 hrs. Intracellular ROS, OS/hypoxia, mitochondrial membrane potential, steroid-responsive genes expression were analyzed. The results revealed that the effective dose of DEHP (400 µg) significantly increased OS compared to the control by increasing ROS levels, mitochondrial membrane potential, and β-galactosidase activity with a higher level of apoptotic genes (Bax, Caspase-3) expression at mRNA level. Further, DEHP significantly (p < 0.05) reduced mRNA expression of steroidogenic responsive genes (StAR, CYP17A1, and CYP19A1) in granulosa cells treated with above combination compared to control. Interestingly, co-treatment of DEHP + Shatavarin-IV significantly suppressed the DEHP induced OS, ROS, β-galactosidase levels and enhanced steroidogeneic and apoptotic gene expression activities, which suggests that Shatavarin-IV rescued DEHP-induced changes that may useful for the prevention of DEHP- induced reproductive toxicity. © 2024 Elsevier Inc.

In this article, a flavonol-Aib conjugate; {(4-oxo-2-phenyl-4-H-chromen-3-yl-2-((start-butoxy-carbonyl) amino)-2-methyl-propanoate) (3A)} has been synthesized, purified and characterized through 1H and 13C NMR, mass spectrometry and X-ray crystallography. X-ray crystallography of these molecules revealed that this is a flavonol-Aib conjugate; there is no intramolecular hydrogen bond, while two intermolecular H-bonds occur between two molecules of flavonol-Aib conjugate, between O2 of C=O (flavonol ring) and H1 (Aib NH) is 2.183Å. This intermolecular interaction generates a stacked two-dimensional (2-D) structure. There are weak interactions between H3 of the flavonol-benzene ring and H18B of the tertiary Butyl-CH3 is 2.804Å., and the same H3 interaction with other molecules' H14 of phenyl of substituted flavonol is 2.332Å. The distance between O2 of C=O (flavonol ring) and H11 (other phenyl-substituted flavonol rings) is 2.610Å, giving a specific molecular conformation. A complete molecular structure investigation of the molecule shows that several inter- and intramolecular weak to strong interactions lead to a peculiar array of molecules in two and three dimensions. In silico studies, molecular docking via Auto doc vina reveals that flavonol with 2-aminoisobutyric acid conjugate, among conjugates of different amino acids (glycine, alanine, valine, leucine, Isoleucine), Aib conjugate shows highest binding affinity with CDC42 (-7.7), BCL2L1 (-8.9), GSK3B (-6.8), MAPK1 (-8.8), PPARG (-7.4), ICAM1 (-7.8), MMP9 (8.0), BCL2 (-8.9), ERBB2 (-9,0), HSP90A1 (9.5) gene. The result of in vitro studies exhibits remarkable inhibitory ability with IC50 values of 400 µg/ml. The overall outcome indicates that flavonol conjugated with 2-aminoisobutyric acid (Aib) can inhibit the growth of the MCF-7 cancer cell line by targeting multiple biological pathways. © 2025
