[Description]

2-Ethyl-5,7-dimethyl-3H-imidazo[4,5-b]pyridine is a nonpeptidic angiotensin II receptor antagonist whose imidazo[4,5-b]pyridine scaffold has been used to examine a variety of positional substitutions in the development of orally active, long duration antihypertensive agents.

[in vitro]

in a previous study, 2-ethyl-5,7-dimethyl-3h-imidazo[4,5-b]pyridine was synthezed by reduction of 2-amino-3-nitropyridine derivatives to the corresponding diaminopyridine which was then condensed with an appropriate carboxylic acid in polyphosphoric acid. in vitro activity study showed that 2-ethyl-5,7-dimethyl-3h-imidazo[4,5-b]pyridine was a nonpeptidic angiotensin ii receptor antagonist whose imidazo[4,5-b]pyridine scaffold had been used to examine plenty of positional substitutions in the development of orally active, long duration antihypertensive agents [1].
