The present invention provide the following Sulfonamide derivatives which have low toxicity and a potent effect of inhibiting tubulin polymerization. The pharmaceutical compositions containing the said compound as an active ingredient correct abnormalities in the immune system and are useful as preventives or remedies of rheumatism such as inflammatory rheumatism or as anticancer agents.
That is, the present invention relates to Sulfonamide derivatives represented by the general formula(1)
[wherein preferably R1 is a lower alkyl group, R2 , R3, R4, R5, R6 may be the same or different and each independently represents a hydrogen atom, a halogen atom, a nitro group, a lower alkyl group, an optionally substituted amino group or alkyl group. A represents any group of (1)an optionally substituted 5-membered heterocyclic group (except triazolyl group)whose ring members include at least 1 nitrogen atom and may include any atom(s) selected from the group consisting nitrogen atom, oxygen atom, and sulfur atom, (2)an optionally substituted alicyclic group, and (3)an alicyclic group whose ring members include at least 1 nitrogen atom and may include any atom(s) selected from the group consisting of nitrogen atom, oxygen atom, and sulfur atom], and the pharmaceutically acceptable salts thereof and the use thereof as a pharmaceutical composition.
本发明提供了以下磺酰胺衍生物,它们具有低毒性和抑制微管蛋白聚合的强效作用。含有上述化合物作为活性成分的药物组合物可以纠正免疫系统的异常,并可作为风湿病(如炎症性风湿病)的预防或治疗药物或抗癌药物。
也就是说,本发明涉及通式(1)所代表的磺酰胺衍生物
[其中 R1 优选为低级烷基,R2、R3、R4、R5、R6 可以相同或不同,且各自独立地代表氢原子、卤素原子、硝基、低级烷基、任选取代的氨基或烷基。A 代表以下任一基团:(1)任选取代的 5 元杂环基团(三唑基除外),其环成员至少包括 1 个氮原子,并可包括从氮原子、氧原子和硫原子组成的组中选出的任一(多个)原子;(2)任选取代的脂环族基团,其环成员至少包括 1 个氮原子,并可包括从氮原子、氧原子和硫原子组成的组中选出的任一(多个)原子;(3)任选取代的脂环族基团、和 (3)脂环族基团,其环成员包括至少 1 个氮原子,并可包括任选自氮原子、氧原子和硫原子组成的组中的原子],及其药学上可接受的盐,以及其作为药物组合物的用途。
