Poly(beta-benzyl-L-aspartate)-block-poly(vinylpyrrolidone) diblock copolymers (PAsp(OBzl)-b-PVP) having both hydrophobic and hydrophilic segments of various lengths were synthesized by a combination of ATRP and ROP. These amphiphilic diblock copolymers formed polymeric micelles consisting of a hydrophobic PAsp(OBzl) core and a hydrophilic PVP shell

A series of copoly(alpha-amino acids) with varying percentages of hydrophilic (L-aspartic acid) and hydrophobic monomers (L-leucine, beta-methyl-L-aspartate, and beta-benzyl-L-aspartate) were implanted subcutaneously in rats and the macroscopic degradation behavior was studied. Three groups of materials (A,B,C) with different ranges of

Herein, the synthesis of an amino-acid-based di-block copolymer (di-BCP) in-between an l-glutamic acid-5-benzyl ester and l-aspartic acid-4-benzyl ester [(l-GluA-5-BE)-b-(l-AspA-4-BE)] has been reported. However, the synthesis of di-BCP of [(l-GluA-5-BE)-b-(l-AspA-4-BE)] was carried out through the facile modified ring-opening polymerization (ROP) without

The Fmoc-based SPPS of H-Xaa-Asp(OBzl)-Yaa-Gly-NH(2) sequences results in side reactions yielding not only aspartimide peptides and piperidide derivatives, but also 1,4-diazepine-2,5-dione-peptides. Evidence is presented to show that the 1,4-diazepine-2,5-dione derivative is formed from the aspartimide peptide. The rate of this
