further elucidated by jointly using DOX computational protocol, MM-PBSA and site-directed mutagenesis assays. The positive results suggest that strategy adopted in this study was promising to rapidly discovery the potent inhibitors with novel scaffolds. The satisfactory algicide activities suggest that the thiourea derivatives is very likely to be a promising lead for the development of novel specific
通过使用新的基于片段的虚拟筛选策略,从果蓝藻(CyFBA)的果糖-1、6-二磷酸醛缩酶的活性位点重新发现了两个系列的新型FBA-II抑制剂(硫脲衍生物)。相比之下,与N-(苯基氨基甲硫酰基)苯甲酰胺衍生物(L1-L13)相比,大多数N-(2-苯甲酰基肼-1-碳硫基)苯甲酰胺衍生物(L14〜L22)显示出更高的CyFBA-II抑制活性。尤其是,化合物L14不仅显示出较高的CyFBA-II活性(Ki = 0.65μM),而且还显示出最有效的针对拟球藻sp。的体内活性。PCC 6803(EC50 = 0.09 ppm),比以前的抑制剂(EC50 = 0.6 ppm)高(7倍)。通过联合使用DOX计算方案,MM-PBSA和定点诱变分析进一步阐明了化合物L14和CyFBA-II的结合模式。积极的结果表明,这项研究中采用的策略有望迅速发现具有新型支架的有效抑制剂。令人满意的除藻剂活性表明,硫脲衍生物很
