The synthesis of three new analogues of the cyclic cationic antimicrobial peptide Gramicidin S is described. These derivatives contain a modified turn region in which the DPhe-Pro motif has been replaced by a constrained furanoid sugar amino acid or a flexible linear aminoethoxy acetic acid moiety. Structural analysis revealed conformational changes in the modified turn region compared to GS. The biological
描述了环状阳离子抗菌肽短杆菌肽 S 的三种新类似物的合成。这些衍生物含有修饰的转角区,其中 DPhe-Pro 基序已被限制性呋喃糖氨基酸或灵活的线性氨基乙氧基乙酸部分取代。结构分析揭示了与 GS 相比,修饰的转角区域的构象变化。然而,这些化合物的生物学特征类似于短杆菌肽 S 和先前描述的类似物。© 2009 Wiley-VCH Verlag GmbH & Co. KGaA,魏因海姆。
