Abstract

In the present study, (N-acryloyl-L-cysteine-benzyl amide)2 (Acryl-L-Cys-NHBn)2, N-acryloyl-L-histidine-benzyl amide (Acryl-L-His-NHBn), and N-acryloyl-aspartic acid-benzyl amide (Acryl-L-Asp-NHBn) were chemo-enzymatically synthesized from Boc-L-amino acids. Then, a mixture of these acryl amino acid monomers was copolymerized to form polymers. The resulting random polymers were then activated after a mercaptoethanol-triggered reduction of disulfide linkages to thiol. The activated polymer demonstrated substrate selectivity, turnover, and rate enhancement in catalyzing the hydrolysis of the esters of Cbz-glycine. The results demonstrated that radical polymerization can facilitate the task of preparing synthetic macromolecules capable of enzyme-like catalytic turnover, substrate selectivity, and rate enhancement.
