Pipecolic acid-containing peptolides wherein the peptidic backbone is of at least 9 a-amino acid residues joined together by peptide bonds, particularly the compounds of formula I
wherein the substituents have various significances, are disclosed.
They can be prepared by isolation or derivation from an appropriate microorganism strain such as S 42508/F (NRRL 15761).
They have interesting pharmacological, e.g. antifungal, chemotherapeutic drug resistance reversing and to some extent immunosuppressant and antiinflammatory properties.
含联哌
羧酸的
多肽,其中肽骨架由至少 9 个通过肽键连接在一起的 a-
氨基酸残基组成,特别是式 I 的化合物
其中的取代基具有各种意义。
它们可以通过从适当的微
生物菌株(如 S 42508/F(NRRL 15761))中分离或衍生制备。
它们具有有趣的药理特性,例如抗真菌、逆转化疗药物耐药性,以及在一定程度上的免疫抑制和抗炎特性。
