Abstract:
:Guided by co-crystal structural information obtained from a different series we were exploring, a scaffold morphing and SBDD approach led to the discovery of the 1,4-disubstituted indazole series as a novel class of GKAs that potently activate GK in enzyme and cell assays. anti-diabetic OGTT efficacy was demonstrated with 29 in a rodent models of type 2 diabetes.
