ty 11345

TY 11345 is a proton pump inhibitor.

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.

Nepaprazole Na is the salt form of Nepaprazole Free Base, also known as TY-11345, is a proton pump inhibitor potentially for treatment of gastric ulcer. 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 (concentrations that inhibit the enzyme activity by 50%) being 5.8 microM and 9.9 microM at pH 6.0 and pH 7.4, respectively. TY-11345 should be useful for the clinical treatment of peptic ulcer diseases.
