Studies on nonpeptide angiotensin II receptor antagonists. II. Synthesis and biological evaluation of 5H-pyrazolo[1,5-b][1,2,4]triazole derivatives with a C-linked oxygen functional group at the 6-position

2,7-Diethyl-5H-pyrazolo[1,5-b][1,2,4]triazole derivatives were synthesized and evaluated for activity as angiotensin II receptor antagonists. Replacement of the C-6 hydrogen with C-linked oxygen functional groups led to derivatives with increased in vitro

Pyrazolotriazole derivatives

This invention relates to a pyrazolotriazole derivative represented by the general formula: STR1 wherein each symbol means as follows; R1, R3 and R4 : one of them represents hydrogen, tetrazolylated biphenylmethyl or lower
