Some 1-substituted 3-aryl-1,4-dihydro-1,2,4-triazino[4,3-a]- benzimidazoles and their vasodilatory activities

Abstract

In this study, some 1-substituted 3-aryl-1,4-dihydro-1,2,4- triazino[4,3-a]benzimidazole derivatives were synthesized, their structures were elucidated, and their vasodilatory activities were examined. It was found that the compounds under investigation showed appreciable vasodilatory activity.
