Novel, cyclic peptidomimetics were synthesized by facile acylation reactions using benzotriazole chemistry. Microbiological testing of the synthesized compounds revealed an exceptionally high activity against Candida albicans with a minimum inhibitory concentration (MIC) two orders of magnitude lower than the MIC of the antifungal reference drug amphotericin B. A strikingly high activity was also observed
使用苯并三唑化学反应通过酰化反应合成了新型环状拟肽。合成化合物的微生物学测试显示,其对白色念珠菌具有极高的活性,其最低抑菌浓度(MIC)比抗真菌参考药物两性霉素B的MIC低两个数量级。对三种革兰氏阴性菌也观察到极高的活性细菌菌株(铜绿假单胞菌,肺炎克雷伯菌和变形杆菌)),其中两种是已知的人类病原体。因此,发现的化学型是潜在的多药理学剂。如对五种不同的人类细胞系(HeLa,宫颈; PC-3,前列腺; MCF-7,乳腺; HepG2,肝; HCT-116,结肠)所证明的,发现对哺乳动物肿瘤细胞的毒性很低。使用3D-药效团和2D-QSAR研究了实验数据的内部一致性。
