Description

Relebactam is a β-lactamase (AmpC) inhibitor that can irreversibly inhibit Class A (extended-spectrum β-lactamase and KPC enzymes) and Class C AmpC[1]. Relebactam is a diazabicyclooctane derivative that covalently binds to the active site serine residue of β-lactamase, irreversibly inhibiting its ability to hydrolyze β-lactam antibiotics, thereby restoring the bactericidal activity of imipenem against enzyme-producing resistant bacteria[2]. The combination of Relebactam and Imipenem can significantly reduce the minimum inhibitory concentration (MIC) and improve the efficacy against resistant bacteria (such as Pseudomonas aeruginosa and Klebsiella pneumoniae)[3, 4]. Relebactam can reduce the MIC of multiple cephalosporins and carbapenems against Mycobacterium abscessus[5].

Relebactam是一种β-内酰胺酶(AmpC)抑制剂,能够不可逆地抑制 A类(超广谱β内酰胺酶和KPC酶)和C类AmpC[1]。Relebactam属于二氮杂双环辛烷衍生物,通过共价结合β-内酰胺酶的活性位点丝氨酸残基,不可逆抑制其水解β-内酰胺类抗生素的能力,从而恢复亚胺培南对产酶耐药菌的杀菌活性[2]。Relebactam与亚胺培南(Imipenem)联用能够显著降低最小抑菌浓度(MIC),提升对耐药菌(如铜绿假单胞菌、肺炎克雷伯菌)的疗效[3, 4]。Relebactam能够降低多种头孢菌素和碳青霉烯对脓肿分枝杆菌(Mycobacterium abscessus)的MIC[5]
