Synthesis of a cyclic peptide/protein using the NEXT-A reaction followed by cyclization

Hamamoto, Toshimasa,Sisido, Masahiko,Ohtsuki, Takashi,Taki, Masumi

, p. 9116 - 9118 (2011/10/04)

By using the NEXT-A reaction, we introduced a non-natural amino acid at the N-terminus of a peptide/protein that contained a cysteine unit. The side chain of the introduced amino acid spontaneously reacted with the cysteine to afford a cyclic peptide/protein.
