In the present study, the analgesic and anti-inflammatory activities of a new alkaloid (5′-Hydroxymethyl-1′(1,2,3,9-tetrahydro-pyrrolo [2,1-b] quinazolin-1-yl)-heptan-1-one) (compound 1), isolated from Sida cordifolia Linn. was investigated in animal models. The analgesic activity was investigated in the acetic acid induced writhing and the radiant heat(More)
[Reaction: see text]. A highly efficient synthetic method of carotenoid compounds has been developed on the basis of the sulfone coupling and double-elimination strategy. This method highlighted the sulfone-mediated coupling with the novel C(10) dialdehyde, 2,7-dimethyl-4-octenedial, which was easily prepared and efficiently utilized in the synthesis of the(More)
