Discovery of Pyrrolidine-Containing GPR40 Agonists: Stereochemistry Effects a Change in Binding Mode

A novel series of pyrrolidine-containing GPR40 agonists is described as a potential treatment for type 2 diabetes. The initial pyrrolidine hit was modified by moving the position of the carboxylic acid, a key pharmacophore for GPR40. Addition of a 4-cis-CF3 to the pyrrolidine improves the human GPR40 binding Ki and agonist efficacy. After further optimization, the discovery of a minor enantiomeric impurity with agonist activity led to the finding that enantiomers (R,R)-68 and (S,S)-68 have differential effects on the radioligand used for the binding assay, with (R,R)-68 potentiating the radioligand and (S,S)-68 displacing the radioligand. Compound (R,R)-68 activates both Gq-coupled intracellular Ca2+ flux and Gs-coupled cAMP accumulation. This signaling bias results in a dual mechanism of action for compound (R,R)-68, demonstrating glucose-dependent insulin and GLP-1 secretion in vitro. In vivo, compound (R,R)-68 significantly lowers plasma glucose levels in mice during an oral glucose challenge, encouraging further development of the series.

Stereoselective synthesis of novel chimerical amino acids via a photochemical key step

The synthesis of novel chimerical amino acid derivatives 6-8 bearing the 6-azatricyclo[3.3.1.033,7]nonane (methanotropane) skeleton is described. Starting with one chirality centre in L-4-oxoprolines 2 we succeeded in the fully stereoselective introduction of four new chirality centres. The key step of our synthetic route is a photochemical cyclization of phenyl ketones, whose stereoselectivity has been explained by the different stability of the triplet biradical conformers.
