Title: Yonghan Chen: Innovator in Pharmaceutical Synthesis

Introduction

Yonghan Chen is a notable inventor based in Guangdong, China. He has made significant contributions to the field of pharmaceutical synthesis, particularly through his innovative methods.

Latest Patents

Yonghan Chen holds a patent for a method for synthesizing Etelcalcetide. This method involves solid phase synthesis, which includes synthesizing the Etelcalcetide backbone peptide resin, removing the side chain protecting group of Cys in the peptide chain, and activating the sulfhydryl group of the Cys side chain on the peptide resin with 2,2'-dithiodipyridine. The process constructs a disulfide bond with L-Cys, resulting in a crude Etelcalcetide peptide. This method is advantageous as it does not require multi-step purification, leading to relatively high yield and purity of the obtained crude peptide, and significantly increasing the total yield of the refined peptide after purification.
