A series of novel 1,2,3-triazole-etodolac hybrids (6a-l) were designed and synthesized as potent anticancer molecules. The synthesis strongly relied on Huisgen's 1,3-dipolar cycloaddition between etodolac azide 3 and substituted terminal alkynes 5a-l. The use of CH 2 Cl 2 as a co-solvent with H 2 O increased the reaction rate and provided the corresponding 1,2,3-triazole-etodolac hybrids (6a-l) in excellent yields compared to other organic co-solvent systems. All the compounds were screened for their in vitro anticancer activity against human A549 cell lines and compounds 6e, 6f, 6h, 6j, and 6l were found to be the best anti-cancer molecules as compared to the marketed drug doxorubicin.

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.
