[Preparation and pharmacologic activity of amido- derivatives of 3-methyl-3,4-dihydro benzo- and pyrido-1,2,4-triazin-3-acetic acids]

Abstract

Thirteen amidoderivatives of 3-methyl-3,4-dihydro-6-R-benzo-1,2,4-triazin-3-yl-acetic acids and of 3-methyl-3,4-dihydro-pyrido [3,2-e]/[3,4-e]-1,2,4-triazin- 3-yl-acetic acids were prepared and submitted to a wide pharmacological screening. The dihydrobenzotriazine and dihydropyridotriazine moieties were endowed with a wide pharmacogenic capacity; in fact, several compounds exhibited high antiinflammatory [(I c), (I d), (II d), (V f), (VI f)], diuretic [(I f), (I g), (I h)] and antihypertensive activities [(I d), (III d)], as well as minor effects on the C.N.S.
