The synthesis of β-lactamase inhibitory activity of a series of sodium 6-[(1-heteroarylthioethyl-1, 2, 3-triazol-4-yl)methylene]pemcillanate 1, 1-dioxides are described. Their activity was compared with tazobactam and sulbactam. The Z-isomers were more active than the E-isomers. The in vitro activity of the Z-isomers of the phenylthiadiazole derivatives (13a and 15a) was better than sulbactam against the tested β-lactamases and comparable to tazobactam especially against TEM-2 and cephalosporinase. But their synergistic activity with five antibiotics was inferior to tazobactam.
描述了一系列具有β-内酰胺酶抑制活性的6-[(1-杂芳基硫乙基-1,2,3-三唑-4-基)亚甲基]半纤维素钠1,1-二氧化物的合成。将它们的活性与他佐巴坦和舒巴坦进行比较。 Z-异构体比E-异构体更活跃。苯基噻二唑衍生物的 Z-异构体(13a 和 15a)的体外活性优于舒巴坦,对抗测试的 β-内酰胺酶,与他唑巴坦相当,尤其是对抗 TEM-2 和头孢菌素酶。但它们与五种抗生素的协同活性不如他佐巴坦。
