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 tRNA
Lys
(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.
Mechanistic studies on counter-ionic effects of camphorsulfonate-based ionic liquids on kinetics, thermodynamics and stereoselectivity of β-amino carbonyl compounds
Catalysis is important in various applications of organic chemistry and its output product control for stereoselective compounds is outrageous. Establishment of experimental facts of stereoselective compounds from catalysis and their validation using theoretical evidences is the key to understand various mechanisms of optically active compounds. A family of new ionicliquids (ILs) with various imidazolium
