A compound of formula:
(X1-X2-His-X3-CO)n-R (I)
where:
X1is H or an amino acid residue of cysteine (Cys) having L or D configuration, wherein each pair of amino acid residues of Cys, optionally present as X1, can be in the form of a cystine residue owing to an -S-S- bridge formed by the -SH functions of two Cys residues,
X2is an amino acid residue of tyrosine (Tyr) or of histidine (His) having L or D configuration,
X3is an amino acid residue of His or Tyr having L or D configuration, provided, however, that X2 is Tyr when X3 is His and X2 is His when X3 is Tyr,
Hisis an amino acid residue of histidine having L or D configuration,
nis an integer of from 1 to 4,
Rwhen n is 1, is OH, a residue of a single amino acid, or a peptide chain comprising from 2 to 7 amino acids,
whereas,
when n is 2, 3 or 4, it is a group capable of forming a dimer, a trimer and, respectively, a tetramer.
式的化合物:
(X1-X2-His-X3-CO)n-R (I)
其中
X1 是 H 或具有 L 或 D 构型的半胱氨酸(Cys)的氨基酸残基,其中由于两个 Cys 残基的 -SH 功能形成的-S-S-桥,每对 Cys 的氨基酸残基(可选择作为 X1 存在)可以是胱氨酸残基的形式、
X2 是具有 L 或 D 构型的酪氨酸(Tyr)或组氨酸(His)的氨基酸残基、
X3 是具有 L 或 D 构型的 His 或 Tyr 的氨基酸残基,但条件是当 X3 是 His 时,X2 是 Tyr;当 X3 是 Tyr 时,X2 是 His、
His 是组氨酸的氨基酸残基,具有 L 或 D 构型、
n 是 1 至 4 的整数、
当 n 为 1 时,为 OH、单个氨基酸残基或由 2 至 7 个氨基酸组成的肽链、
而
当 n 为 2、3 或 4 时,是能够分别形成二聚体、三聚体和四聚体的基团。
