Abstract:A series of dipeptide derivatives containing non-coded amino acids, N-Boc-4-X-Phe-Ala-NHNHPh (X=Cl, Br, I, NO 2), were synthesized by using thermoase in organic solvents. The physical data were consistent with the same samples prepared by 3-(diethoxyphosphoryloxy)-1,2,3-benzotriazin-4(3H)-one (DEPBT). Influence of different substituted groups of the non-coded amino acids and different organic solvents on the enzymatic peptide synthesis was studied.
Keywords:thermoase  DEPBT  non-coded amino acid  enzymatic synthesis  peptide
