Pyrrolomycins (PMs) are polyhalogenated antibiotics known as powerful biologically active compounds, yet featuring high cytotoxicity. The present study reports the antibacterial and antitumoral properties of new chemically synthesized PMs, where the three positions of the pyrrolic nucleus were replaced by nitro groups, aiming to reduce their cytotoxicity while maintaining or even enhancing the biological activity
: 吡咯霉素(PMs)是多卤代抗生素,被称为强大的生物活性化合物,但具有很高的细胞毒性。本研究报告了新型化学合成PM的抗菌和抗肿瘤特性,其中吡咯核的三个位置被硝基取代,目的是在保持甚至增强生物学活性的同时降低其细胞毒性。实际上,在吡咯的不同位置存在硝基取代基决定了革兰氏阳性菌(即金黄色葡萄球菌) 或阴性菌(即铜绿假单胞菌)的最低杀菌浓度(MBC)有所提高。)与天然PM-C相比的病原菌菌株。此外,一些新的硝基-PM在抑制结肠癌(HCT116)和乳腺癌(MCF 7)癌细胞系增殖方面的活性与PM-C相同或更高,并且对正常上皮(hTERT RPE-1)细胞的毒性较小。总而言之,我们的发现有助于增加对这些有前途的分子的作用方式的了解,并为其化学或生物操作的原理提供基础。
