title: 3N-methylbiphenylsulfonylurea and -carbamate substituted imidazo[4,5-b]pyridines. Potent antagonists of the ANG II AT1 receptors.
abstract: The synthesis and the SAR study of imidazo[4,5-b]pyridine biphenyl sulfonylureas and -carbamates as highly potent AT1-selective ANG II receptor antagonists are described. Several members of this new class of antagonists efficiently inhibited the ANG II-induced pressor response in pithed rats after iv and intraduodenal (id) administration.
