Abstract
Fungal endophytes are a known warehouse of bioactive compounds with multifarious applications. In the present investigation two compounds, β-Sitosterol (1) and ursolic acid (2), were isolated from Alternaria alternata, an endophytic fungus associated with Morus alba Linn for the first time. The structure of the compounds was elucidated on the basis of comprehensive spectral analysis (UV, IR, 1 H-, 13 C- and 2D-NMR, as well as HRESI-MS). In the in vitro alpha amylase inhibitory assay both compounds (1) and (2) show potent antidiabetic activity. In support, Docking studies indicate significant binding affinity of the isolated compounds. Hence from the present study, it can be concluded that endophytic fungi in Morus alba Linn can find use in antidiabetic drug development in the medicinal industry.Communicated by Ramaswamy H. Sarma.

Bu-Shen-Tian-Jing formulas alleviate the mitochondrial damage induced by oxidative stress in ovarian granulosa cells exposed to DEHP through the HDAC3-HSP90AA pathway. PHARMACEUTICAL BIOLOGY 2023; 61:1387-1400. [PMID: 37655754 PMCID: PMC10478627 DOI: 10.1080/13880209.2023.2249193] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/03/2022] [Revised: 07/03/2023] [Accepted: 08/12/2023] [Indexed: 09/02/2023]
Abstract
CONTEXT di-(2-Ethylhexyl) phthalate (DEHP) has potential reproductive toxicity. Bu-Shen-Tian-Jing formulations (BSTJFs) are beneficial for female reproductive capacity. However, BSTJF2 has much lower cytotoxicity than BSTJF1. OBJECTIVE To investigate the effects of BSTJFs on ovarian granulosa cells exposed to DEHP and determine the potential molecular mechanisms. METHODS AND MATERIALS Human granulosa-like tumor cell line (KGN) cells were divided into control, DEHP, BSTJF1 and BSTJF2 groups. The DEHP group were given 1 μM DEHP for 24 h. They were then given BSTJF1 at 200 μg/mL or BSTJF2 at 100 μg/mL for 24 h. The control group was treated with the same concentration of DMSO (0.1%). Oxidative stress and mitochondrial function were measured. The mRNA and protein expression levels of HDAC3 and HSP90AA were determined. Integrative network pharmacology analysis of BSTJF2 was also performed. RESULTS DEHP (1 μM) significantly suppressed the proliferation of KGN cells by 17%, significantly increased ROS levels by 28% and MDA levels by 47%, significantly decreased MMP levels by 22% and mtDNA copy by 30%. DEHP significantly increased protein expression of HDAC3 by 21%and HSP90AA by 64%. All these changes were significantly reversed by BSTJFs. Integrative network pharmacology analysis revealed HSP90AA was a key target (degree = 8). Both RGFP966 and BSTJF2 significantly reversed the increased expression of HDAC3 and HSP90AA, attenuated oxidative stress, and mitochondrial damage which were induced by DEHP. CONCLUSION BSTJFs might have therapeutic potential on oxidative stress and mitochondrial damage through the HDAC3/HSP90AA pathway which encourages further clinical trials.

Abstract
Osteoporosis is becoming a major concern in the field of public health. The process of bone loss is insidious and does not directly induce obvious symptoms. Complications indicate an irreversible decrease in bone mass. The high-risk populations of osteoporosis, including postmenopausal women, elderly men, diabetic patients and obese individuals need regular bone mineral density testing and appropriate preventive treatment. However, the primary changes in these populations are different, increasing the difficulty of effective treatment of osteoporosis. Determining the core pathogenesis of osteoporosis helps improve the efficiency and efficacy of treatment among these populations. Oxidative stress is a common pathological state secondary to estrogen deficiency, aging, hyperglycemia and hyperlipemia. In this review, we divided oxidative stress into the direct effect of reactive oxygen species (ROS) and the reduction of antioxidant enzyme activity to discuss their roles in the development of osteoporosis. ROS initiated mitochondrial apoptotic signaling and suppressed osteogenic marker expression to weaken osteogenesis. MAPK and NF-κB signaling pathways mediated the positive effect of ROS on osteoclast differentiation. Antioxidant enzymes not only eliminate the negative effects of ROS, but also directly participate in the regulation of bone metabolism. Additionally, we also described the roles of proinflammatory factors and HIF-1α under the pathophysiological changes of inflammation and hypoxia, which provided a supplement of oxidative stress-induced osteoporosis. In conclusion, our review showed that oxidative stress was a common pathological state in a high-risk population for osteoporosis. Targeted oxidative stress treatment would greatly optimize the therapeutic schedule of various osteoporosis treatments.

Abstract
ContextGastric ulcer (GU) a widely distributed ailment is associated with many causes, including alcohol consumption.Materials and MethodsChemical profiling of Symphyotrichum squamatum ethanol extract (SSEE) was established via ultra-performance liquid chromatography/quadrupole time-of-flight mass spectrometry (UPLC-qTOF-MS) and employed in a silver nano-formulation (SSEE-N-Ag). SSEE and SSEE-N-Ag antiulcer activities were estimated against ethanol-induced rats by biochemical, histological, and metabolomics assessments. Reduced glutathione, total antioxidant capacity and prostaglandin E2 levels and gastric mucosa histopathological examination were analysed. The rats' metabolome changing alongside action pathways were elucidated via metabolite profile coupled to multivariate data analysis.ResultsUPLC-MS profiling of SSEE identified 75 components belonging to various classes. Compared with control, EtOH-treated rats showed decreased of tissue GSH, TAC and PGE2 by 62.32%, 51.85% and 47.03% respectively. SSEE and SSEE-N-Ag administration mitigated biochemical and histopathological alterations. Serum metabolomics analysis revealed for changes in several low molecular weight metabolites with ulcer development. These metabolites levels were restored to normal post-administration of SSEE-N-Ag. SSEE-N-Ag as mediated via modulating numerous metabolic pathways such as lipids, pyrimidine, energy metabolism and phosphatidylinositol signalling. This study provides novel insight for metabolic mechanisms underlying gastric ulcer relieving effect.ConclusionPresent results revealed potential antiulcer effect of SSEE and SSEE-N-Ag by decreasing ulcer-associated syndromes, supporting their anti-ulcerogenic action.

Chemical Profile of Cyperus laevigatus and Its Protective Effects against Thioacetamide-Induced Hepatorenal Toxicity in Rats. Molecules 2022; 27:molecules27196470. [PMID: 36235007 PMCID: PMC9573427 DOI: 10.3390/molecules27196470] [Citation(s) in RCA: 13] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2022] [Revised: 09/21/2022] [Accepted: 09/27/2022] [Indexed: 11/17/2022] Open
Abstract
Cyperus species represent a group of cosmopolitan plants used in folk medicine to treat several diseases. In the current study, the phytochemical profile of Cyperus laevigatus ethanolic extract (CLEE) was assessed using UPLC-QTOF-MS/MS. The protective effect of CLEE at 50 and 100 mg /kg body weight (b.w.) was evaluated on hepatorenal injuries induced by thioacetamide (100 mg/kg) via investigation of the extract's effects on oxidative stress, inflammatory markers and histopathological changes in the liver and kidney. UPLC-QTOF-MS/MS analysis of CLEE resulted in the identification of 94 compounds, including organic and phenolic acids, flavones, aurones, and fatty acids. CLEE improved the antioxidant status in the liver and kidney, as manifested by enhancement of reduced glutathione (GSH) and coenzyme Q10 (CoQ10), in addition to the reduction in malondialdehyde (MDA), nitric oxide (NO), and 8-hydroxy-2'-deoxyguanosine (8OHdG). Moreover, CLEE positively affected oxidative stress parameters in plasma and thwarted the depletion of hepatorenal ATP content by thioacetamide (TAA). Furthermore, treatment of rats with CLEE alleviated the significant increase in plasma liver enzymes, kidney function parameters, and inflammatory markers. The protective effect of CLEE was confirmed by a histopathological study of the liver and kidney. Our results proposed that CLEE may reduce TAA-hepatorenal toxicity via its antioxidant and anti-inflammatory properties suppressing oxidative stress.
