Abstract A variety of substituted tetrahydropyrido [4, 3-d] pyrimidines was prepared and found to possess gastric antilesion against ethanol-induced lesions in rats. The more potent compounds possessed similar activity against aspirin-induced gastric lesions. A selective group of compounds was determined to be inactive as gastric antisecretory agents in rabbit isolated parietal cells. The antilesion properties of these tetrahydropyrido [4, 3-d] ...
