This invention provides certain benzenesulfonamide derivatives of formula (I) and methods for using them in the treatment of susceptible neoplasms in mammals. Also provided are certain novel pharmaceutical formulations employing these benzenesulfonamide derivatives in combination with a carrier, and processes for preparing the benzenesulfonamide derivatives.
wherein:
R¹ is -NO₂,
or -NRaRb, where Ra and Rb are independently selected from the group consisting of hydrogen and C₁-C₆ alkyl; and
R² and R³ are independently selected from the group consisting of hydrogen, halo, C₁-C₆ alkyl, and trifluoromethyl, provided that no more than one of R² and R³ can be hydrogen;
with the proviso that if R¹ is -NO₂ or -NH₂, neither R² nor R³ can be hydrogen;
or a pharmaceutically acceptable salt or solvate thereof.
本发明提供了某些式(I)的苯磺酰胺衍生物以及用它们治疗哺乳动物易感肿瘤的方法。本发明还提供了某些采用这些苯磺酰胺衍生物与载体结合的新型药物制剂,以及制备苯磺酰胺衍生物的工艺。
其中
R¹ 是-NO₂、
或-NRaRb,其中 Ra 和 Rb 独立选自由氢和 C₁-C₆ 烷基组成的组;以及
R² 和 R³ 独立地选自氢、卤代、C₁-C₆ 烷基和三氟甲基组成的组,但 R² 和 R³ 中不能有一个以上是氢;
但如果 R¹ 是-NO₂或-NH₂,则 R² 和 R³ 均不能是氢;
或其药学上可接受的盐或溶液。
