A structure-activity relationship study of the imidazolyl-beta-tetrahydrocarboline series identified MK-4256 as a potent, selective SSTR3 antagonist, which demonstrated superior efficacy in a mouse oGTT model. MK-4256 reduced glucose excursion in a dose-dependent fashion with maximal efficacy achieved at doses as low as 0.03 mg/kg po. As compared with glipizide, MK-4256 showed a minimal hypoglycemia risk in mice.

Route development and demonstration on multikilogramscale for the first GMP delivery of MK-4256 are described. Key aspects of the convergent route include a regioselective green iodination, one-pot oxadiazole synthesis, and an efficient ketone Pictet–Spengler reaction with diastereomeric upgrade via crystallization to afford 6 kg of API. A recycle procedure augmented the yield of desired diastereomer
