Irumban puli (Averrhoa bilimbi) is commonly used as a traditional remedy in the state of Kerala. Freshly made concentrated juice has a very high oxalic acid content and consumption carries a high risk of developing acute renal failure (ARF) by deposition of calcium oxalate crystals in renal tubules. Acute oxalate nephropathy (AON) due to secondary oxalosis(More)
In continuing search for compounds with immunomodulatory activity, plant Aralia cachemirica has been found to contain continentalic acid (CA). Isolation of this pharmacologically significant diterpinic acid from Aralia cachemirica is novel. Chemical structure of this compound was identified by spectral analysis as (-)-pimara-8(14), 15-dien-19-oic acid,(More)
Reactions of organic molecules on Montmorillonite clay mineral have been investigated from various aspects. These include catalytic reactions for organic synthesis, chemical evolution, the mechanism of humus-formation, and environmental problems. Catalysis by clay minerals has attracted much interest recently, and many reports including the catalysis by(More)
One-pot heterocyclic synthesis is an exciting research area as it can open routes for the development of otherwise complex transformations in organic synthesis. Heterocyclic compounds show wide spectrum of applications in medicinal chemistry, chemical biology, and materials science. These heterocycles can be generated very efficiently through highly(More)
In the last decades a number of pyrazole and isoxazole derivatives have been introduced in clinical practice. The therapeutic effectiveness of these agents has been bounded by a number of limiting factors. Due to this, the development of novel, selective, potent and safe agents remains in high priority in medicinal chemistry research. Synthans, such as(More)
Exceedingly facile protocols based on the reactivity of corresponding oxoketenedithioacetal (4), 2-(dimethylaminomethylene) ketone (5), β-oxoenolether (6) and α, β-unsaturated ketone (7) resulted from 7-ethyl-3,4 dihydroazepino[3,2-b] carbazole-2,5 (1H,7H)-dione (3) on its reaction with base catalyzed condensation of (a) CS2+ MeI (b) DMF-DMA (c) H-COOEt and(More)
