The reaction of ethyl benzoylacetate with formaldehyde and natural amino acid ester hydrochlorides in acetate buffer (AcONa/AcOH, pH 4.0) at room temperature afforded 41-61% of new 5-benzoylhexahydropyrimidine derivatives. The synthesized compounds were evaluated for their in vitro cytotoxic activity against normal (HEK293) and tumor cell lines (Jurkat, HepG2). T-Lymphoblastic leukemia Jurkat cells turned out to be most sensitive to the examined hexahydropyrimidine derivatives. Ethyl 5-benzoyl-1,3-bis[2-ethoxy-1-(4-hydroxy benzyl)-2-oxoethyl]hexahydropyrimidine-5-carboxylate showed the highest cytotoxic activity against all tested cell lines.
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.
