ABSTRACTMembers of a family ofN-arylsulfonyl hydrazones have been identified as novel inhibitors of IMP-1, a metallo-β-lactamase of increasing prevalence. Structure-activity relationship studies have indicated a requirement for bulky aromatic substituents on each side of the sulfonyl hydrazone backbone for these compounds to serve as efficient inhibitors of IMP-1. Molecular modeling has provided insight into the structural basis for the anti-metallo-β-lactamase activity exhibited by this class of compounds.
摘要N-芳基磺酰腙家族的成员已被确认为 IMP-1 的新型抑制剂,IMP-1 是一种日益普遍的金属-β-内酰胺酶。结构-活性关系研究表明,要使这些化合物成为 IMP-1 的高效抑制剂,磺酰肼骨架的两侧必须有大体积的芳香取代基。分子建模深入揭示了这类化合物具有抗金属-β-内酰胺酶活性的结构基础。
