3-amino-5-[2-(ethylamino)-4-pyridyl]-1,2,4-triazole (4), a competitive histamineH2-receptorantagonist structurally unrelated to, but more potent than, cimetidine. A QSAR study on a subset of analogues closely related to 4 showed that gastric acid antisecretory activity increased with decreasing lipophilicity. An SAR study about 4 focused on (1) pyridine substitution compatible with both unidentate and bidentate
