peptic ulcer diseases

Linaprazan glurate 抑制外源性或内源性刺激的胃酸分泌。 Linaprazan glurate 可用于胃肠道炎症性疾病和消化性溃疡疾病的研究。

5-Hydroxylansoprazole (AG1908) 是血浆中 Lansoprazole 的活性代谢产物，对质子泵有抑制作用，可用于研究消化性溃疡。

Vonoprazan hydrochloride 是一种高效且具口服活性的质子泵抑制剂 (PPI) 和钾竞争性酸阻断剂 (potassium-competitive acid blocker, P-CAB)，展示出优秀的抗分泌活性。在 pH 为 6.5 的条件下，该化合物可抑制猪胃微粒体内 H+,K+-ATPase 的酶活性，呈现出 19 nM 的 IC50 值。Vonoprazan hydrochloride 主要应用于胃酸相关疾病的研究，包括胃食管反流病和消化性溃疡，并可用于根除幽门螺杆菌。

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.

Urease-IN-11 (化合物 6e)，IC50 值为 10.41 µM，是一种有效的竞争性脲酶 (Urease) 抑制剂。它主要用于研究由脲酶引起的胃炎、消化性溃疡等相关疾病。
