lubiprostone

Lubiprostone (RU-0211) 是一种 ClC-2 氯化物通道的激活剂，用于治疗特发性慢性便秘。

Lubiprostone (hemiketal) (RU-0211 (hemiketal)) 作为CLCN2激活剂，能够选择性地增强氯离子通道2功能。通过促进肠道氯离子的分泌，Lubiprostone (hemiketal) 提高了肠内液体的产生并优化肠蠕动，主要应用于处理慢性特发性便秘及阿片类药物引起的便秘。此外，该化合物也被用于慢性便秘和癌症的相关研究。

Prostaglandin E1 (PGE1), synthesized through cyclooxygenase-mediated metabolism of dihomo-γ-linolenic acid (DGLA), functions by inhibiting platelet aggregation (IC50= 40 nM) and enhancing vasodilation. Its analog, 13,14-dihydro-16,16-difluoro PGE1, and the metabolite, 13,14-dihydro PGE1, both retain similar anti-aggregatory properties to the original compound. The inclusion of two electron-withdrawing fluorine atoms in 13,14-dihydro-16,16-difluoro PGE1 is believed to increase molecular stability and potentially extend bioavailability by resisting hydrolytic degradation.
