An object of the invention is to provide a peptide having a stabilized secondary structure.
The present invention provides a peptide having a secondary structure stabilized by a crosslinked structure and containing at least one combination of a special amino acid of the formula (I):
(wherein, (A) represents a single bond or a linking group having, in the main chain thereof, from 1 to 10 atoms;
(B) represents a group containing at least one π bond;
(C) represents a hydrogen atom or an alkyl group which may be substituted with a substituent; and X represents a group substitutable by a substitution reaction with a sulfanyl group) and an amino acid having, in the side chain thereof, a sulfanyl group; and having the crosslinked structure formed through a thioether bond between the side chain of the special amino acid residue and the sulfanyl group.
本发明的目的是提供一种具有稳定二级结构的
多肽。
