On April 25, 2013, Ogamino, Takahisa; Yamazaki, Yukiyoshi; Tanikawa, Shin; Okuda, Ayumu; Fukuda, Tomoaki; Tokuda, Okihisa; Miyake, Yoshiharu; Itoh, Shinsuke; Ishiwata, Hiroyuki published a patent.Product Details of 64987-16-2 The title of the patent was Preparation of spiroindoline compounds for activating glucokinase. And the patent contained the following:
Title compounds I [ring A = nitrogen-containing heterocyclyl; R1, R2 = independently H, halo, haloalkyl, etc.; R3 = H, (un)substituted alkyl, -COR7, etc.; R7 = H, (un)substituted alkyl, haloalkyl, etc.; R4 = H, halo, cyano, etc.; or salts or solvates thereof], useful for the treatment of diabetes, glucose intolerance, metabolic syndrome, etc., were prepared For example, reaction of 2-amino-5-chlorothiazole·HCl with 4-nitrophenyl chloroformate, treatment with tert-Bu 5-bromospiro[indoline-3,3′-pyrrolidine]-1′-carboxylate, deprotection using CF3CO2H, and acetylation afforded compound II. The invention compounds activated glucokinase activity in vitro assay, e.g., III showed 1192% activation at 1 μmol/L. The experimental process involved the reaction of Methyl 2-(2-aminothiazol-4-yl)acetate(cas: 64987-16-2).Product Details of 64987-16-2
