reasons for the drug resistance is the existence of β-lactamases especially metallo-β-lactamases such as New Delhi metallo-β-lactamase (NDM-1) and Verona Integron-encoded metallo-β-lactamase (VIM-2). The fungal natural product Aspergillomarasmine A (AMA) has proven to be a promising inhibitor of NDM-1 and VIM-2 both in vitro and in vivo. Seven new analogues of AMA were synthesized by utilizing different
革兰氏阴性细菌对β-内酰胺类抗生素的耐药性已显示是一个至关重要的全球性健康问题。产生耐药性的主要原因之一是存在β-内酰胺酶,尤其是金属β-内酰胺酶,例如新德里金属β-内酰胺酶(NDM-1)和维罗纳整合素编码的金属β-内酰胺酶(VIM-2) )。事实证明,在体外和体内,真菌天然产物曲霉芦荟A(AMA)都是一种有前途的NDM-1和VIM-2抑制剂。通过使用不同的策略合成了七个新的AMA类似物。对这些类似物进行了生物学评估以研究AMA在体外和体内的构效关系。引人注目的铅化合物4与美罗培南组合显示出协同作用,以克服革兰氏阴性细菌(如表达NDM-1的肺炎克雷伯氏菌(BAA-2146))的抗生素抗性。
