Introduction: Immunity boosting has emerged as a global strategy to fight the SARS-CoV-2 pandemic situation. In India, AYUSH systems of medicine have been promoted as an immune-protection strategy. Andrographis paniculata (Burm. F) Nees (AP) mentioned in Ayurveda has been widely used for treating sore throat, flu, and upper respiratory tract infections which may provide possible novel therapeutic approaches, exclusively targeting SARS-CoV-2 and its pathways.Objectives: The present work uses liquid chromatography-tandem mass spectrometry (LC-MS/MS) metabolomics and combination synergy analysis based on network pharmacology to mine multimode evidence to understand the possible mechanism of action, diseases association, protein-protein interaction and major pathways involved therein.Material and methods: Metabolite profiling was performed by Agilent QTOF LC-MS/MS system. Network pharmacology analysis was performed by using functional annotation analysis based on databases like Binding DB, STRING, DAVID and KEGG for further data mining. Further combination synergy was evaluated using "neighbourhood approach" and networks were constructed through Cytoscape 3.2.1.
Results:The molecules from kalmegh provides immune-protection and anti-viral response via involving different pathways, like toll-like receptor pathway, PI3/AKT pathway and MAP kinase pathways against COVID-19 infection. The KEGG analysis showed that in a vast majority of the most enriched pathways, AP were associated with viral infections and upper respiratory tract infections.
Conclusions:The results suggest a synergy between andrographolide and other molecules identified as safe and efficacious anti-inflammatory agent having effects on upper respiratory tract infections and can significantly decrease the production of cytokines and pro-inflammatory factors in viral infections.
IntroductionClerodendron infortunatum Linn. (Verbenaceae), commonly known as Bhant in Hindi, is a small shrub occurring throughout the plains of India, which is traditionally used for several medicinal purposes. The aim of the present study was to evaluate the preclinical antihyperglycemic activity of the methanol extract of the leaves of C. infortunatum (MECI) in Wistar rats.MethodsHyperglycemia was induced in rats by a single intraperitoneal injection of streptozotocin (STZ, 65 mg/kg body weight). Three days after STZ induction, the hyperglycemic rats were treated with MECI intraperitoneally at the doses of 250 and 500 mg/kg body weight daily for 15 days. Glibenclamide (0.5 mg/kg, orally) was used as a reference drug. The fasting blood glucose levels were measured on every fifth day during the 15 days of treatment. Serum biochemical parameters such as glutamate pyruvate transaminase, glutamate oxaloacetate transaminase, alkaline phosphatase, cholesterol, and total protein were estimated. Antioxidant properties were assessed by estimating hepatic lipid peroxidation, reduced glutathione (GSH), and catalase (CAT).ResultsMECI at the doses of 250 and 500 mg/kg intraperitoneally significantly (P<0.001) and dose-dependently reduced and normalized blood glucose levels as compared to that of the STZ control group. Serum biochemical parameters were significantly (P<0.001) restored towards normal levels in MECI-treated rats as compared to the STZ control. MECI treatment also significantly (P<0.001) decreased lipid peroxidation and recovered GSH levels and CAT activity towards normal values, as compared to the STZ control.ConclusionThe present study demonstrated that the leaves of C. infortunatum had remarkable preclinical antihyperglycemic activity in STZ-induced diabetic rats.
SUMMARYIn present study evaluate the analgesic and anti-inflammatory activity of the compound obtained from the petroleum ether (40 -60°C) extract of the fruits from Dregea volubilis in Swiss albino mice and in Wister albino rats respectively. Dried and crushed fruits of Dregea volubilis were extracted by petroleum ether (40 -60°C), the proper solvent system was developed by TLC and subjected to column chromatography for obtaining the pure compound/s. IR, MASS, NMR (PMR, C13 NMR and DEPT) spectroscopic analysis were done to elucidate the structure of the compound/s. The petroleum ether (40 -60°C) extract of the fruits of Dregea volubilis led to isolation of a pentacyclic triterpenoid designated as taraxerone and characterized as D-friedoolean-14-en, 3 one. Taraxerone had been screened for analgesic activity in Swiss albino mice and anti-inflammatory activity in Wister albino rats at the dose of 5 mg/kg body weight orally and exhibit significant analgesic and anti-inflammatory properties.
An investigation of non-statistical fluctuation of the compound multiplicity spectrum in 32S–AgBr interactions at 200 AGeV in terms of factorial correlators is presented. It is observed that the correlated moments increase with decrease in bin–bin separation D, following a power law, which suggests the presence of an intermittent nature of self-similar dynamical fluctuation patterns in the compound multiplicity spectrum. The data also support the α model of intermittency.
Background:Trichosanthes dioica Roxb. (Cucurbitaceae), called pointed gourd in English is a dioecious climber grown in India and used traditionally for various medicinal purposes.Methods:Present study was aimed to evaluate in vitro cytotoxic effect of dichloromethane (DCTD), methanol (METD), and aqueous (AQTD) extracts of T. dioica root using Allium cepa root meristems by keeping them in different concentrations of each test extract under specific experimental conditions followed by determination of root growth inhibition (root length and number) and mitotic index.Results:All the extracts significantly demonstrated concentration-dependent inhibition of root length and number and reduction in mitotic index, indicating antimitotic activity demonstrating cytotoxicity and genotoxicity. DCTD was found to be the most potent (EC50 : 2.8 mg/ml), followed by METD and AQTD.Conclusion:The present study therefore, establishes promising in vitro cytotoxic and genotoxic property of T. dioica root against the test system.
