This invention provides certain sulfonamidoquinoxaline 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 sulfonamidoquinoxaline derivatives, in combination with a carrier, diluent or excipient.
wherein:
A is phenyl, naphthyl, heterocyclic, or unsaturated heterocyclic,
said groups being optionally substituted with one or more halo, trifluoromethyl, C₁-C₆ alkyl, or -NR³R⁴,
where R³ and R⁴ are independently selected from the group consisting of hydrogen and C₁-C₆ alkyl;
R¹ and R² are independently selected from the group consisting of hydrogen, trifluoromethyl, halo, and C₁-C₆ alkyl, provided that R¹ and R² cannot both be hydrogen;
provided that when one of R¹ and R² is hydrogen and the other is halo, R³ and R⁴ cannot both be hydrogen;
or a tautomer or salt or solvate thereof.
本发明提供了某些式(I)的磺酰胺基喹喔啉衍生物以及使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新型药物制剂,这些药物制剂采用了这些磺酰胺基喹喔啉衍生物与载体、稀释剂或赋形剂的组合。
其中
A 是苯基、萘基、杂环或不饱和杂环、
所述基团任选被一个或多个卤代、三氟甲基、C₁-C₆ 烷基或 -NR³R⁴ 取代、
其中 R³ 和 R⁴ 独立选自由氢和 C₁-C₆ 烷基组成的组;
R¹ 和 R² 独立选自由氢、三氟甲基、卤代和 C₁-C₆ 烷基组成的组,但 R¹ 和 R² 不能都是氢;
当 R¹ 和 R² 中的一个是氢,另一个是卤素时,R³ 和 R⁴ 不能都是氢;
或其同系物、盐或溶液。
