A peptide of formula (I) (H.sub.2 N--X.sub.1 --Thr--X.sub.2 --CO).sub.n --R (I) where X.sub.1 and X.sub.2, different one another, are an amino acid residue of arginine or tyrosine in configuration L or D, wherein the hydroxy group of threonine and tyrosine and the guanidine moiety of arginine may be protected by a compound conventionally used in peptide chemistry for protecting the hydroxy group and the guanidine moiety, respectively, n is 1, 2, 3 or 4, and R, when n is 2, 3 or 4, is a group suitable for forming a dimer, trimer or tetramer, while, when n is 1, R is OH, a single amino acid residue, or a peptide chain containing up to 7 amino acid residues.
化学式为(I)的肽(H.sub.2 N--X.sub.1 --Thr--X.sub.2 --CO).sub.n --R(I),其中X.sub.1和X.sub.2彼此不同,是精氨酸或酪氨酸的氨基酸残基,配置为L或D,若甘氨酸的胍基团和苏氨酸和酪氨酸的羟基团需要保护,则可使用肽化学中常用的化合物进行保护,n为1、2、3或4,当n为2、3或4时,R是适合形成二聚体、三聚体或四聚体的基团,而当n为1时,R是OH、单个氨基酸残基或包含最多7个氨基酸残基的肽链。
