pentadentate). The chosen peptides were mainly based on the known sequence of the C-terminus of the bacterial peptidoglycan precursors. Biological evaluation on clinical bacterial isolates, harbouring either the NDM-1 or VIM-2 metallo-β-lactamase, showed a clear relationship between the zinc chelator strength and restoration of meropenem activity. However, evaluation of toxicity on different cancer cell lines
已经进行了包括具有不同锌亲和力的螯合部分的金属-β-内酰胺酶抑制剂的合成,以及部分受细菌肽序列启发的肽的合成。锌螯合剂的强度使用下列螯合剂来改变,这些螯合剂按结合亲和力的升序排列:二聚烯丙基胺(DPA,三齿),二聚烯丙基-1,2,3-三唑基甲胺(DPTA,四齿)二聚烯丙基乙二胺(DPED,四齿)和三吡啶基乙二胺(TPED,五齿)。选择的肽主要基于细菌肽聚糖前体的C末端的已知序列。对具有NDM-1或VIM-2金属-β-内酰胺酶的临床细菌分离株的生物学评估表明,锌螯合剂的强度与美罗培南活性的恢复之间存在明确的关系。然而,
