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

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

Chem Commun (Camb)

Department of Medical and Bioengineering Science, Chemical Biology Area, Division of Chemistry and Biochemistry, Okayama University, 1-1-1, Tsushimanaka, Okayama, 700-0082, Japan.

Published: August 2011
