Abstract
本发明的目的是式I的化合物,它们的药用盐,对映异构体形式,非对映异构体形式和外消旋物,上述化合物的制备,包含它们的药物及其制备,以及上述化合物用于控制或预防疾病如癌症的应用。
Description
本发明涉及新的杂环基吡啶基磺酰胺衍生物,它们的制备方法,包含它们的药物组合物及其制备以及这些化合物作为药用活性剂的应用。
发明背景
癌症疾病的治疗在医学中是非常重要的。在世界范围内都存在对于有效癌症疗法的需求,目的在于获得适合于患者并且是靶标定向的治疗。这可以在最近在应用肿瘤学和与癌症治疗相关的基础研究领域中出现的大量科学研究中看到。
肿瘤抑制剂的作用是由非常广泛多样的机制所导致的,仅了解这些机制中的一些。发现已知肿瘤药物具有新的作用机制,这并不少见。这对于本发明的化合物而言预计也是如此。许多肿瘤药物通过这样机制作用,所述机制如阻滞细胞中细胞分裂的机制,防止给肿瘤供应营养物和氧(抗血管发生),预防转移,防止肿瘤细胞接收并向外传递生长信号或迫使肿瘤细胞进入编程性细胞死亡(细胞调亡)。
因为它们具有不同的作用机制,包括与不同的细胞内靶标相互作用,所以临床相关的细胞生长抑制剂经常组合施用从而获得协同治疗作用。
Delarge,J.和Ghys,A.,Ann.Pharm.Fr.41(1983)55-60,描述了一些具有降血脂(hypolipemic)性质的4-苯基硫代吡啶-3-磺酰胺。US 4,018,929涉及作为炎症抑制剂和利尿剂的吡啶磺酰胺。Owa,T.等,Bioorg.Med.Chem.Lett.(生物有机药物化学通讯)12(2002)2097-2100涉及作为抗肿瘤剂的N-(7-吲哚基)-3-吡啶磺酰胺衍生物。
