  Improving the Pharmacokinetics of GPR40/FFA1 Full Agonists

  摘要：

  We recently reported the discovery of a potent GPR40 full agonist AM-1638 (1). Herein, we describe our efforts in improving the drug-like properties of the full agonists through the systematic introduction of polar groups in the C-, D-, and A-rings. This led to the discovery of new GPR40 full agonists with significantly improved pharmacokinetic propeties. Compound 8 and 20 also showed potent in vivo efficacy in oral glucose tolerance tests in mice in addition to the improvement in properties.

  Transition-metal-catalyzed C–H alkylation reactions directed by aldehydes or ketones have been largely restricted to electronically activated alkenes. Herein, we report a general protocol for the Ir(III)-catalyzed ortho C–H alkylations of (hetero)aromatic aldehydes using alkyl boron reagents as the coupling partner. Featuring aniline as an inexpensive catalytic ligand, the method was compatible with
