Abstact

Design, synthesis, and SAR of 7-oxopyrrolopyridine-derived DPP4 inhibitors are described. The preferred stereochemistry of these atropisomeric biaryl analogs has been identified as Sa. Compound (+)-3t, with a K(i) against DPP4, DPP8, and DPP9 of 0.37 nM, 2.2, and 5.7 μM, respectively, showed a significant improvement in insulin response after single doses of 3 and 10 μmol/kg in ob/ob mice.
