New substituted cephalosporin sulfones are disclosed having the structural formula:
wherein M is, e.g., trifluoromethyl, chloro or fluoro or-COOH; R1 is, e.g., hydrogen, hydroxy, mercapto, substituted oxy, substituted thio, hydrocarbyl or substituted hydrocarbyl group; B is OB1 or NB2B3 wherein B1 and B2 independently are, e.g., straight or branched chain alkyl having from 1 to 20 carbon atoms, aryl having from 6 to 10 carbon atoms or cycloalkyl having from 3 to 8 carbon atoms; B3 is B1 or hydrogen; and Q is, e.g., hydrogen, C1-6alkyl, halo C1-6alkyl or hydroxy C1-6alkyl. Those compounds are potent elastase inhibitors and thereby useful antiinflammatory/antidegenerative agents. A process for preparing those compounds is also disclosed.
公开了具有以下结构式的新取代头孢砜:
其中 M 是例如三氟甲基、氯或氟或-COOH; R1 是例如氢、羟基、巯基、取代氧基、取代硫代、烃基或取代烃基; B 是 OB1 或 NB2B3 其中 B1 和 B2 独立地是例如具有 1 至 20 个碳原子的直链或支链烷基、具有 6 至 10 个碳原子的芳基或环基、B3 是 B1 或氢;Q 是氢、C1-6 烷基、卤代 C1-6 烷基或羟基 C1-6 烷基。这些化合物是有效的弹性蛋白酶抑制剂,因此是有用的抗炎/抗变性剂。还公开了制备这些化合物的工艺。
