ABSTRACT

A novel class of N-aryl-2-acylindole human glucagon receptor (hGCGR) antagonists is reported. These compounds demonstrate good pharmacokinetic profiles in multiple preclinical species. One compound from this series, indole 33, is orally active in a transgenic murine pharmacodynamic model. Furthermore, a 1mg/kg oral dose of indole 33 lowers ambient glucose levels in an ob/ob/hGCGR transgenic murine diabetes model. This compound was deemed suitable for preclinical safety studies and was found to be well tolerated in an 8-day experimental rodent tolerability study. The combination of preclinical efficacy and safety observed with compound 33 highlights the potential of this class as a treatment for type 2 diabetes.
