    • There are disclosed peptides having the following formula:A--X--Z--Y--Bwherein A is ##STR1## X is a suitable neutral, aliphatic or aromatic amino acid residue; e.g., one selected from the group consisting of ALA, 2-Me-ALA, GLY, LEU, ILE, LYS, THR, SER, PHE, MET, D-ALA, D-LEU, D-ILE, D-LYS, D-THR, allo-THR, D-SER, D-PHE, D-MET, and SAR; Z is ##STR2## Y is GLY, SER, THR, LEU, ILE, VAL, OR SAR; B IS TYR-R', D-TYR-R', decarboxy-TYR, or ##STR3## m is 3 or 4; n is 1, 2, or 3; R''' is hydrogen, C.sub.1 -C.sub.7 alkyl, C.sub.6 -C.sub.12 aryl, or C.sub.1 -C.sub.7 alkanoyl; and R and R' are substituents which do not substantially affect the biological activity of the peptides, provided that R-ARG-LYS-ASP-VAL-TYR-R' is excluded. These peptides have the capability of inducing the differentiation of T-lymphocytes but not of complement receptor (CR.sup.+) B-lymphocytes and thus are useful in a number of therapeutic areas. Also provided are derivatives of the peptides, therapeutic compositions, and methods for use of the compositions.
    • 公开了具有下式的肽:A-X-Z-Y-B其中A是合适的中性,脂族或芳族氨基酸残基; 例如选自ALA,2-Me-​​ALA,GLY,LEU,ILE,LYS,THR,SER,PHE,MET,D-ALA,D-LEU,D-ILE,D-LYS,D -THR,allo-THR,D-SER,D-PHE,D-MET和SAR; Z是 Y是GLY,SER,THR,LEU,ILE,VAL或OR SAR; B是TYR-R',D-TYR-R',脱羧-TYR或者 m是3或4; n为1,2或3; R“是氢,C 1 -C 7烷基,C 6 -C 12芳基或C 1 -C 7烷酰基; 并且R和R'是不排除基本上影响肽的生物学活性的取代基,条件是R-ARG-LYS-ASP-VAL-TYR-R'。 这些肽具有诱导T淋巴细胞分化而不是补体受体(CR +)B淋巴细胞分化的能力,因此可用于许多治疗领域。 还提供了肽的衍生物,治疗组合物和组合物的使用方法。
