Novel cyclic peptide derivatives based on ogipeptins A, B, C, and D were synthesized. Starting with a mixture of ogipeptins A–D, a practical four-step synthetic procedure was followed to prepare novel derivatives with various kinds of acyl side chains. Among the 45 new synthetic derivatives identified, the antibacterial activities of compounds 8-3 and 8-38 were comparable with those of ogipeptin A
合成了基于 ogipeptins A、B、C 和 D 的新型环肽衍生物。从 ogipeptins A-D 的混合物开始,遵循实用的四步合成程序来制备具有各种酰基侧链的新型衍生物。中标识的45个新的合成衍生物,化合物的抗菌活性8-3和8-38分别与ogipeptin A的可比较的在体外肾毒性使用LLC-PK1细胞的筛选中,化合物8-3和8-38显示显著下细胞毒性 (LD 20 > 480 μM) 高于粘菌素 (LD 20 = 44.2 μM)。
