Reported herein is a relebactam-derived fluorogenic reagent for covalent labeling of serine β-lactamases (SBLs), which are the major causes of bacterial resistance to β-lactam antibiotics. This highly selective imaging reagent generates over 300-fold stronger near-infrared fluorescence signals upon covalently bonding to SBLs, allowing wash-free visualization of live antimicrobial-resistant bacteria.
本文报道了一种雷巴他定衍生的荧光探针，用于共价标记丝氨酸β-内酰胺酶（SBLs），SBLs 是导致细菌对β-内酰胺类抗生素产生耐药性的主要原因。这种高度选择性的成像试剂与 SBLs 发生共价键合后会产生超过 300 倍的近红外荧光信号，可实现无需洗涤即可实时可视化抗微生物耐药菌。
