toward expanding the spectrum to allow treatment of a wider range of organisms. Through key structural modifications of a bicyclic lead, stepwise gains in spectrum of inhibition were achieved, ultimately resulting in QPX7728 (35). This compound displays a remarkably broad spectrum of inhibition, including class B and class D enzymes, and is little affected by porin modifications and efflux. Compound
尽管β-内酰胺酶抑制剂领域取得了重大进展,但某些酶仍对最近引入的药物的抑制作用具有抵抗力。其中最重要的是肠杆菌科的B类(金属)酶NDM-1和鲍曼不动杆菌的D类(OXA)酶。继续实施导致vaborbactam的硼酸计划,努力扩大光谱范围,以治疗更广泛的生物。通过双环先导的关键结构修饰,抑制谱逐步提高,最终得到QPX7728(35)。该化合物显示出极大的抑制谱,包括B类和D类酶,几乎不受孔蛋白修饰和外排的影响。化合物35 是与β-内酰胺类抗生素组合使用的有前途的药物,可通过静脉内和口服给药治疗多种多重耐药性革兰氏阴性细菌感染。
