Nine newly synthesized eugenol derivatives were investigated in rats or mice as to their anesthetic, hypothermic, myorelaxant and anticonvulsant effects. Additional pharmacological activity which appeared during the experiments is described. For comparative purposes, six naturally occurring eugenol analogues were included in the study. The results are further discussed as to possible structure-activity relationships between the test compounds and the four investigated effects.
The in vivo administration of 59Fe to the rat accompanied by acetylsalicylic acid (ASA) enhanced significantly counts in blood, spleen, liver and femur without affecting those of the intestine. The results suggest that ASA augments iron absorption either via an inhibitory action on the synthesis of prostaglandins or by a purely chemical mechanism.
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.
