Carbazole-containing amides and ureas: Discovery of cryptochrome modulators as antihyperglycemic agents

A series of novel carbazole-containing amides and ureas were synthesized. A structure-activity relationship study of these compounds led to the identification of potent cryptochrome modulators. Based on the desired pharmacokinetic/pharmacodynamic parameters and the results of efficacy studies in db/db mice, compound 50 was selected for further profiling.
