absorption properties of the most potent compounds, which were zwitterionic in nature, could be improved by the formation of an internal salt bridge, which helped in shielding the two opposite charges and thus also the high polarity of zwitterions with separated charges. The designed compounds containing such a salt bridge reached high oral bioavailability and oral exposure. We believe that this principle could
G蛋白偶联受体SUCNR1(琥珀酸酯受体1或GPR91)可感知柠檬酸循环中间体琥珀酸酯,并涉及各种病理状况,例如类风湿性关节炎,肝纤维化或肥胖。在这里,我们描述了通过高通量筛选发现的新型SUCNR1拮抗剂支架。最有效的化合物(本质上是两性离子)的较差的渗透和吸收性能可以通过形成内部盐桥来改善,该盐桥有助于屏蔽两个相反的电荷,从而也可以保护带有分离电荷的两性离子的高极性。设计的含有这种盐桥的化合物达到了很高的口服生物利用度和口服暴露。
