A series consisting of 30 novel imidazo [4,5-b]pyridine benzohydrazones have been synthesized and evaluated for their antiglycation activity as well as their antioxidative potential. The synthetic part involves a 3-step reaction in which a pyridine diamine was being converted into a imidazo [4,5-b]pyridine, which was then subjected through another reaction to yield benzohydrazide. Subsequently, the attained benzohydrazide of imidazo[4,5-b]pyridine was used to synthesize the target molecules after treating them with the appropriate benzohydrazone derivatives. The derivatives were evaluated for the antiglycation and antioxidant activities. Result obtained showed that di and trihydroxy substituted compounds showed good activity with compound 25 (140.16 ± 0.36 lM) having the most potent antiglycation activity, which is twice lower than Rutin. The results also showed
The plant kingdom has served as one of man's oldest sources of useful drugs. They are remarkable in their ability to produce a vast number of diverse secondary metabolites ranging in chemical complexity and biological activities. Natural products (NPs) have historically served as templates for the modern drug development. The Garcinia species are known to be rich in
Phytochemical studies on the methanolic extract of the leaves of Garcinia griffithii (Guttiferae) afforded two known xanthones derivatives, 1,3,5,6-Tetrahydroxy-7-(3-methylbut-2-enyl)xanthone (1) and Rubraxanthone (2). The structures of these xanthones derivatives were determined on the basis of extensive spectroscopic data interpretation and comparison with data reported in the literature. In an in vitro test, compound 1 and 2 showed the ability to inhibit platelet aggregation in human whole blood which induced by arachidonic acid (AA), adenosine diphosphate (ADP) and collagen.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
