lipophilic inhibitors of the DXR, the second enzyme of the MEP pathway for the biosynthesis of isoprene units in most bacteria, by replacing the phosphonate group of fosmidomycin derivatives by a tetrazoyl moiety capable of multiple hydrogen bonding. The N- and C-substituted tetrazole analogues of phosphonohydroxamate inhibitors were synthesized and tested on the DXR of Escherichia coli. This work
这项工作的重点是新型抗菌药物的设计以及DXR的亲脂性抑制剂的开发,DXR是大多数细菌中异戊二烯单元生物合成的MEP途径的第二种酶,通过用四唑基取代膦酰胺衍生物的膦酸酯基能够进行多个氢键键合的部分 合成了膦酰基异羟肟酸酯抑制剂的N-和C-取代的四唑类似物,并在大肠杆菌的DXR上进行了测试。这项工作指出了一个假设,即膦酸酯/磷酸盐识别位点可能太刚性而无法容纳其他官能团。
