    摘要: The present application provides a preparation method of a formamide compound, the preparation process includes: uniformly mixing raw material of methanoic acid and an amine compound selected from a primary amine or a secondary amine to prepare a homogeneous reaction system; the above homogeneous reaction system is heated to 160-230° C., allowing carbon monoxide to be decomposed from the homogeneous reaction system and participates in the reaction, and collecting the reaction product to obtain a formamide compound. The present application provides a new technology using a homogeneous method to synthesize a formamide compound, the reaction process needs no use of a catalyst, the operation process is simple and controllable, and the raw material of the amine compound has a high selectivity.

    摘要: 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.
