4-arylazo-3,5-diamino-1H-pyrazoles as a novel group of anti-biofilm agents. Here, we report a SAR study based on 60 analogues by examining ways in which the pharmacophore can be further optimized, for example, via substitutions in the aryl ring. The SAR study revealed the very potent anti-biofilm compound 4-(2-(2-fluorophenyl)hydrazineylidene)-5-imino-4,5-dihydro-1H-pyrazol-3-amine (2).
通过筛选 50 000 种小分子化合物的集合,我们最近将 4-arylazo-3,5-diamino-1 H -pyrazoles 鉴定为一组新型抗生物膜剂。在这里,我们报告了一项基于 60 种类似物的 SAR 研究,通过检查可以进一步优化药效团的方法,例如通过芳环中的取代。SAR 研究揭示了非常有效的抗生物膜化合物 4-(2-(2-fluorophenyl)hydrazineylidene)-5-imino-4,5-dihydro-1 H -pyrazol-3-amine ( 2 )。
