A series of rhodanines was constructed, their Z-configuration was confirmed by small molecule X-ray crystal structures, and their activity against metallo-β-lactamases (MβLs) was measured. The obtained 26 molecules and a thioenolate specifically inhibited the MβL L1 with an IC50 range of 0.02–1.7 μM, and compounds 2h–m exhibited broad-spectrum inhibition of the MβLs NDM-1, VIM-2, ImiS, and L1 with
构造了一系列的罗丹宁,它们的Z-构型通过小分子X射线晶体结构得以证实,并测量了它们对金属-β-内酰胺酶(MβLs)的活性。获得的26个分子和硫代烯酸酯专门抑制MβLL1,IC 50范围为0.02–1.7μM,化合物2h – m表现出广谱抑制MβLsNDM-1,VIM-2,ImiS和L1的IC 50个值<16μM。所有抑制剂均增强了头孢唑林对表达L1的大肠杆菌细胞的抗菌作用,导致MIC降低了2-8倍。对接研究表明2l的硝基(NDM-1,CphA和L1)或羧基(VIM-2)配位一个或两个Zn(II)离子,而抑制剂的N-苯基增强了它与MβLs的疏水相互作用。这些研究表明,二芳基取代的罗丹酮是设计未来MβLs广谱抑制剂的良好支架。
