Glycogen synthase kinase-3 is a multi-functional serine-threonine kinase and is involved in diverse physiological processes, including metabolism, cell cycle, and gene expression by regulating a wide variety of known substrates like glycogen synthase, tau-protein and β-catenin. Aberrant GSK-3 has been involved in diabetes, inflammation, cancer, Alzheimer's… (More)
Two new coumarins, euonidiol (1) and euoniside (2), and a known flavone, luteolin 7-methyl ether, were isolated from the aerial parts of the plant Euonymus hamiltanianus Wall. All the compounds were characterized on the basis of spectral analysis viz. 1H NMR, 13C NMR, DEPT, IR, UV, ESI-MS, and elemental analysis.
Novel pyrimidin-4-one derivatives have been synthesized using EDC coupling and evaluated as glycogen synthase kinase-3β (GSK-3β) inhibitors. Among all the synthesized compounds, compound 5 (3-methyl-6-phenyl-2-(piperazin-1-yl)-3,4-dihydropyrimidin-4-one) exhibited the most potent inhibitory activity against GSK-3β with IC50 value of 74 nm. The molecular… (More)
Recent studies reveal that glycogen synthase kinase-3β (GSK-3β) acts as a pro-inflammatory enzyme, and by inhibiting this kinase, inflammation can be controlled. In this regard, a series of 17 piperazine-linked oxazolo[4,5-b]pyridine-based derivatives was synthesized and evaluated for in vitro GSK-3β inhibitory and in vivo anti-inflammatory activity. The… (More)
A novel series of oxazolo[4,5-b]pyridine-2-one based 1,2,3-triazoles has been synthesized by click chemistry approach and evaluated for in vitro GSK-3β inhibitory activity. Compound 4g showed maximum inhibition with IC50 value of 0.19 μm. Keeping in view the effect of GSK-3β inhibition on inflammation, compounds 4g, 4d, 4f, 4i, 4n and 4q exhibiting… (More)
Two unusual homoisoflavanone compounds named lesjunceol (1) and lesjuncerol (2) were isolated from the aerial parts of the methanolic extract of Lespedeza juncea apart from the other known constituents myrcetin and ß-sitosterol. All the compounds were characterized on the basis of chemical derivatization and spectroscopic methods.
Three new glutinane-type triterpenes, 19α-glutin-5-en-19-ol (1), 2β,15α,21β-glutin-11-ene-2,15,21-triol (2), and 2β,19α-glutin-7,21-diene-2,19-diol (3), were isolated from the stem bark of Euonymus hamiltonianus. Their structures were determined by 1D and 2D NMR along with MS and IR.
A series of benzimidazole based thiadiazole and carbohydrazide conjugates have been synthesized and evaluated for inhibition of glycogen synthase kinase-3β and anti-depressant effect. Compounds 4f, 4j, 5b, 5g and 5i were found to be the most potent inhibitors of GSK-3β in vitro amongst the twenty-five benzimidazole based thiadiazole and carbohydrazide… (More)
The objective of this study was to evaluate the anthelmintic efficacy of Iris hookeriana Linn. rhizome against gastrointestinal nematodes of sheep. A worm motility inhibition assay was used for in vitro study and a faecal egg count reduction assay was used for an in vivo study. The in vitro study revealed anthelmintic effects of crude aqueous extracts and… (More)
GSK-3 specific inhibitors are promising candidates for the treatment of devastating pathologies such as diabetes, neurodegenerative diseases and cancers. We have synthesized a library of pyrimidin-4-one-1,2,3-triazole conjugates using click-chemistry approach and evaluated them as glycogen synthase kinase-3β inhibitors. Compounds 3g, 3j, 3n and 3r were… (More)
