A chemical investigation of the endophytic sp. HBQ95, associated with the medicinal plant Presl, enabled the discovery of four new piperazic acid-bearing cyclodepsipeptides, lydiamycins E-H (-), and one known compound (lydiamycin A). Their chemical structures, including absolute configurations, were defined by a combination of spectroscopic analyses and multiple chemical manipulations. Lydiamycins F-H (-) and A () exhibited antimetastatic activity against PANC-1 human pancreatic cancer cells without significant cytotoxicity.
对与药用植物普雷斯尔(Presl)相关的内生菌 sp. HBQ95 进行的化学研究,发现了四种新的含哌嗪酸环缩肽——利迪亚霉素 E-H(-),以及一种已知化合物(利迪亚霉素 A)。通过光谱分析和多种化学操作相结合的方式确定了它们的化学结构,包括绝对构型。利迪亚霉素 F-H(-)和 A()对 PANC-1 人胰腺癌细胞表现出抗转移活性,且无明显细胞毒性。
