US Patent 9090668 Process for synthesizing cyclic peptide compound

The objective is to provide a novel process for synthesizing a cyclic peptide compound. It is also an objective to provide a novel cyclic peptide compound. The novel process for synthesizing a cyclic peptide compound comprises the steps of: (1) translationally synthesizing a non-cyclic peptide compound having in a molecule a functional group 1 and a functional group 2, which are a pair of functional groups capable of reacting to form a bond, and (2) cyclizing the non-cyclic peptide compound by the reaction of the functional groups 1 and 2 to form a bond. The novel cyclic peptide compound can be synthesized by the process.
