    Abstract: An object of the present invention is to provide a novel therapeutic agent for a patient with type 2 diabetes, a cause of which is the abnormal synthesis of insulin attributed to the abnormal modification of tRNALys (UUU) in pancreatic β cells having Cdkal1 gene mutation. The present inventors have used (1) a screening system using E. coli in which correct translation into luciferase requires frameshift resulting from mistranslation during protein translation, (2) a screening system using the pancreatic islet of Langerhans isolated from a pancreatic β cell-specific Cdkal1-deficient mouse, and (3) a screening system using a pancreatic β cell-specific Cdkal1-deficient mouse, and found that a compound represented by any of the following formulas (I) to (III) can serve as a therapeutic agent for a patient with type 2 diabetes with Cdkal1 gene mutation resulting in the reduced ability to secrete insulin.
