2,4,5-Trimethoxy chalcones and analogues were synthesized from asaronaldehyde derived from β-asarone. These novel compounds when tested against three human tumour cell lines (MCF-7, SW-982 and HeLa) using MTT assay, revealed that chalcones possessing electron donor groups in para position to carbonyl moiety of phenyl ring A, showed better inhibitory(More)
Methyl esters of the β-boswellic acid (BA) and 11-keto-β-boswellic acid (KBA) obtained from Boswellia serrata resin were subjected to Steglich esterification with the different non-steroidal anti-inflammatory drugs (NSAID) viz., ibuprofen, naproxen, diclophenac and indomethacin. The novel hybrids of methyl boswellate (5-8) and that of methyl 11-keto(More)
β-Asarone (2, 4, 5-trimethoxy-(Z)-1-propenylbenzene) was obtained from Acorus calamus. Nitration of β-asarone with AgNO2/I2 in ether yielded 1-(2, 4, 5-trimethoxy phenyl)-2-nitropropene (1) but with NaNO2/I2 in ethylene glycol obtained 1-(2, 4, 5-trimethoxy phenyl)-1-nitropropene (2). Compound 2 was prepared for the first time and characterized using IR,(More)
Though several glycosides of various triterpenes are known, but surprisingly no boswellic acid glycosides are reported so far. With a view to make water soluble boswellic acids, prepared glycosides of 11-keto boswellic acid for the first time. Naturally occurring boswellic acids which are anti-inflammatory agents are lipophylic in nature and thus, become a(More)
Introduction of the oxo group at the allylic position of 3-acetoxy-urs-12-en-24β-oic acid (ABA) in the presence of the sensitive 3α-acetyl group, thereby converting it into 3-acetoxy-urs-12-en-11-oxo-24β-oic acid (AKBA), has been tried with various catalytic oxidizing agents. Among them sodium chlorite with N-hydroxyphthalimide and manganese(III) acetate(More)
