Rioprostil is a methyl prostaglandin E1 analog that decreases gastric acid secretion and enhances the gastric mucus-bicarbonate barrier. It is effective in the treatment of gastric ulcers and gives significant protection against NSAID-induced gastric muco
KAG-308 is an effective selective and orally active agonist of the EP4 receptor (Ki: 2.57 nM and EC50: 17 nM for human EP4 receptor), more selective over EP1, EP2, EP3, and IP receptor. KAG-308 suppresses colitis and promotes histological mucosal healing,
CS-526 is a proton pump inhibitor. The inhibitory mechanism of CS-526 on H+,K+-ATPase was a competitive antagonism to the K+ binding site of H+,K+-ATPase, and it was also a reversible inhibition. CS-526 has a potent antisecretory effect on gastric acid se
Nepaprazole is a proton pump inhibitor. TY-11345 potently inhibited H+/K(+)-ATPase activity in isolated rabbit gastric mucosal microsomes, and the inhibitory effect was enhanced under weak acid conditions, the IC50 being 5.8 microM and 9.9 microM at pH 6.
