  (BLs), including the highly worrying carbapenemases. Whereas inhibitors of these enzymes were recently marketed, they only target serine-carbapenemases (e.g. KPC-type), and no clinically useful inhibitor is available yet to neutralize the class of metallo-β-lactamases (MBLs). We are developing compounds based on the 1,2,4-triazole-3-thione scaffold, which binds to the di-zinc catalytic site of MBLs

  在革兰氏阴性菌中，对 β-内酰胺类抗生素产生耐药性的主要机制是产生一种或多种 β-内酰胺酶 (BLs)，包括令人担忧的碳青霉烯酶。尽管这些酶的抑制剂最近上市，但它们仅针对丝氨酸-碳青霉烯酶（例如 KPC 型），尚无临床上有用的抑制剂来中和金属-β-内酰胺酶 (MBL) 类。我们正在开发基于 1,2,4-三唑-3-硫酮支架的化合物，该支架以原始方式与 MBL 的二锌催化位点结合，我们之前报道了其产生广谱抑制剂的潜力。然而，到目前为止，在微生物测定中只能观察到适度的抗生素增强作用，需要进一步探索以改善外膜渗透。这里，我们合成并表征了一系列在杂环的 4 位具有不同官能化烷基链的化合物。我们发现在烷基链末端存在羧基会产生有效的 VIM 型酶抑制剂K i值在 μM 到亚 μM 范围内，并且该烷基链必须更长或等于丙基链。该结果证实了羧基官能团对 1,2,4-三唑-3-硫酮杂环的 4-取代基的重要性。如

  potent, they represented a promising basis for the development of broad-spectrum MBL inhibitors. Here, we synthesized and characterized a large number of 4-amino-1,2,4-triazole-3-thione-derived Schiff bases. Compared to the previous series, the presence of an aryl moiety at position 4 afforded an average 10-fold increase in potency. Among 90 synthetic compounds, more than half inhibited at least one

  产生金属β-内酰胺酶（MBL）的革兰氏阴性菌对β-内酰胺抗生素的耐药性代表着重大的医学威胁，并且迫切需要开发临床上有用的抑制剂。我们先前报道了MBL催化位点中的5个取代的4-氨基/ H-1,2,4-三唑-3-硫酮化合物的原始结合模式。此外，我们表明，尽管具有中等效力，但它们代表了广谱MBL抑制剂开发的有希望的基础。在这里，我们合成和表征了大量的4-氨基-1,2,4-三唑-3-硫酮衍生的席夫碱。与先前的系列相比，在4位上存在芳基部分可使效力平均提高10倍。在90种合成化合物中，超过一半的化合物抑制了至少六个被测MBL（L1，VIM-4，VIM-2，NDM-1，IMP-1，K i的值在μM至亚μM范围内。几种是广谱抑制剂，也可以抑制临床上最相关的VIM-2和NDM-1。活性化合物通常在位置5处包含卤代，双环芳基或酚基部分，以及在邻苯甲酸，2,4-二羟基苯基，对苄氧基苯基或3-（m-苯甲酰基）-
