for the activity. Changing the benzofuran with either benzothiophene, phenyl, pyridinyl, tolyl, or naphthyl reduces/nullifies the pharmacological action. Besides the anti-enterococcal activity, derivatives 4 and 6 can be used to develop new broad-spectrum antibiotics as they exhibited activity against the wild-type highly virulent Escherichia coli isolate. Moreover, compound 13 was proved to show antifungal
探索一组新的苯基吡唑的构效关系 (SAR) 揭示了一种潜在的抗肠球菌先导化合物12。与苯基吡唑12相连的苯并呋喃部分对粪肠球菌ATCC 51299的作用是万古霉素的 32 倍。此外,根据计算机研究,化合物12有望具有出色的口服生物利用度。通过 SAR 分析,我们发现苯并呋喃侧链对于活性至关重要。用苯并噻吩、苯基、吡啶基、甲苯基或萘基改变苯并呋喃会降低/使药理作用无效。除了抗肠球菌活性外,衍生物4和6可用于开发新的广谱抗生素,因为它们对野生型高毒力大肠杆菌分离株表现出活性。此外,化合物13被证明对白色念珠菌SS5314(野生型)具有抗真菌活性(MIC = 4 μg/ml)。最后,计算机分析表明,这些化合物在吸收、分布、代谢和排泄研究、药物相似性和药代动力学特性方面具有良好的特征。
