Discovery of Novel Tricyclic Full Agonists for the G-Protein-Coupled Niacin Receptor 109A with Minimized Flushing in Rats
摘要:
Tricyclic analogues were rationally designed as the high affinity niacin receptor G-protein-coupled receptor 109A (GPR109A) agonists by overlapping three lead structures. Various tricyclic anthranilide and cycloalkene carboxylic acid full agonists were discovered with excellent in vitro activity. Compound 2g displayed a good therapeutic index regarding free fatty acids (FFA) reduction and vasodilation effects in rats, with very weak cytochrome P450 2C8 (CYP2C8) and cytochrome P450 2C9 (CYP2C9) inhibition, and a good mouse pharmacokinetics (PK) profile.

The first Ir-catalyzed intramolecularasymmetricallylicdearomatization reaction of pyridines, pyrazines, quinolines, and isoquinolines has been developed. Enabled by in situ formed chiral Ir-catalyst, the dearomatized products were isolated in high levels of yield (up to 99% yield) and enantioselectivity (up to 99% ee). It is worth noting that the Me-THQphos ligand is much more efficient than other
已开发出第一个 Ir 催化的吡啶、吡嗪、喹啉和异喹啉的分子内不对称烯丙基脱芳构化反应。通过原位形成的手性 Ir 催化剂,脱芳构化产物以高产率(高达 99% 的产率)和对映选择性(高达 99% ee)分离。值得注意的是,对于吡嗪和某些喹啉的脱芳构化,Me-THQphos 配体比其他测试的配体更有效。进行了脱芳构化反应的机理研究,结果表明了以形成喹啉作为关键中间体的替代方法的可行性。机理研究结果使该反应成为 Reissert 型反应化学中尚不为人知的类型。此外,
