Title: Kazuyuki Sasakura: Innovator in Pharmaceutical Chemistry

Introduction

Kazuyuki Sasakura is a prominent inventor based in Nara, Japan. He has made significant contributions to the field of pharmaceutical chemistry, holding a total of 13 patents. His work focuses on developing innovative methods and reagents that enhance diagnostic processes and drug synthesis.

Latest Patents

Among his latest patents is a method for the determination of N-acetyl-.beta.-D-glucosaminidase (NAGase) activity. This highly sensitive reagent allows for the colorimetric determination of NAGase activity using sodio-3,3'-dichlorophenolsulfonphthaleinyl N-acetyl-.beta.-D-glucosaminide and a buffer. This method enables precise, quick, and easy diagnosis of renal dysfunction. Another notable patent involves novel ortho-(mono-substituted amino)phenylimines, which serve as intermediates for psychotropic drugs and other pharmaceuticals. These compounds can be economically and industrially prepared by reacting anilines with nitriles in the presence of a boron trifluoride ether adduct and a halide-type Lewis acid, along with an organic base if necessary. The imines can also be hydrolyzed with an acid to yield the corresponding ketones.
