A) Compounds selected from the group consisting of a compound of the formula ##STR1## wherein U is ##STR2## m and n are individually 1 or 2 of one, the dotted lines is a single double bond optionally of cis or trans configuration, a is selected from the group consisting of hydrogen, methyl and methylene, Y is selected from the group consisting of hydrogen, residue of an amino acid with an .alpha.-or .omega.-carboxyl and a peptide or 2,3 or 4 amino acids with the amine optionally acylated with an optionally unsaturated aliphatic carboxylic acid of 6 to 24 carbon atoms or alkylated with alkyl of 1 to 8 carbon atoms, R is selected from the group consisting of hydrogen, alkyl of 1 to 8 carbon, alkenyl and alkynyl of 2 to 8 carbon atoms optionally substituted with at least one halogen with the proviso that if Y is hydrogen, alanine or proline and if a is hydrogen, U contains a double bond; and B) their non-toxic, pharmaceutically acceptable salts with bases or acids, the alkyl esters of 1 to 6 carbon atoms and their primary and secondary amides having remarkable immunomodulatric properties and anti-bacterial activity.
从以下化合物组合中选择化合物:其中U为##STR2##,m和n分别为1或2,虚线是一根单独的双键,可选为顺式或反式构型,a选择自氢、甲基和亚甲基组成的群,Y选择自氢、一种氨基酸的残基,具有α-或ω-羧基和一个肽或2、3或4个氨基酸,其胺基可选择酰化,酰基为6至24个碳原子的不饱和脂肪族羧酸或烷基化,烷基为1至8个碳原子,R选择自氢、1至8个碳原子的烷基、2至8个碳原子的烯烃和炔烃,可选择地取代至少一种卤素,但若Y为氢、丙氨酸或脯氨酸,且a为氢,则U含有双键;以及它们与碱或酸形成的非毒性、药用接受的盐、1至6个碳原子的烷基酯及具有显著的免疫调节性质和抗菌活性的一级和二级酰胺。
