Discovery of a Potent and Orally Efficacious TGR5 Receptor Agonist
摘要:
TGR5 is a G protein -coupled receptor (GPCR), activation of which promotes secretion of glucagon-like peptide -1 (GLP-1) and modulates insulin secretion. The 2-thio-imidazole derivative 6g was identified as a novel, potent, and selective TGR5 agonist (hTGR5 EC50 = 57 pM, mTGR5 = 62 pM) with a favorable pharmacokinetic profile. The compound 6g was found to have potent glucose lowering effects in vivo during an oral glucose tolerance test in DIO C57 mice with ED50 of 7.9 mg/kg and ED90 of 29.2 mg/ kg.

development for the synthesis of ZY12201, a novel TGR5 receptor agonist, as a potential clinical candidate is described. A practical, efficient, and scalable synthetic route provided ZY12201 in seven steps and 32% overall yield. The key step involves an inexpensive acetic acid-mediated cyclization of thiourea 6 for the construction of 2-thio-imidazole derivative 7. The developed process demonstrated cost-effective
