5-LO inhibitors with nanomolar IC50 values obtained in cell-free assay, with compound 20 being the most potent (IC50 = 50 nM). Molecular docking and molecular dynamics simulations into the binding site of 5-LO enzyme allowed us to clarify the binding mode of these dual DNase I/5-LO inhibitors. It was shown that compounds 18-20 uniquely show interactions with histidine residues in the catalytic site
合成了11种新的4-(4-氯苯基)噻唑-2-胺,并与9种已知衍生物一起在体外评估了对牛胰腺DNase I的抑制特性。三种化合物(18-20)抑制DNase I的IC50值均低于100 µM,其中化合物19最有效(IC50 = 79.79 µM)。在没有“黄金标准”的情况下用作阳性对照的结晶紫显示出几乎弱了5倍的DNase I抑制作用。Pharma / E-State RQSAR模型阐明了与DNase I抑制有关的关键结构片段。分子对接和分子动力学模拟定义了4-(4-氯苯基)噻唑-2-胺与DNase I最重要的催化残基的相互作用。基于配体的药效团建模和虚拟筛选证实了DNase I抑制所需的4-(4-氯苯基)噻唑-2-胺的化学特征,并证明在可用数据库中不存在结构相似的分子。化合物18-20已显示为非常有效的5-LO抑制剂,在无细胞试验中具有纳摩尔IC50值,其中化合物20最有效(IC50 = 50
