structure–activity relationship study of a new 1-(arylalkyl)-11H-benzo[f]-1,2-dihydropyrido[3,2,c][1,2,5]oxathiazepine 5,5-dioxide series of antimitotic agents. The pharmacological results obtained from previous works allowed us to identify compound 1 as a new cytotoxic agent inhibiting tubulin polymerization. We have undertaken the synthesis of its non-methylated analogue 7 and have extended our investigations
在这里,我们描述了一种新的1-(芳基烷基)-11 H-苯并[ f ] -1,2-二氢吡啶并[3,2,c ] [1,2,5]奥沙西平5,5的结构-活性关系研究-二氧化系列抗有丝分裂剂。从以前的工作中获得的药理结果使我们能够将化合物1鉴定为抑制微管蛋白聚合的新细胞毒剂。我们已经进行了其非甲基化类似物7的合成,并将研究范围扩展到与结构相关的新型二苯并吡啶并恶二氧杂环丁烷系列。在这项研究中合成的所有类似物中,化合物10b最有前途,效力比化合物1高12倍。对于所有测试的组织学类型,其在一组五种肿瘤细胞系中的活性均在纳摩尔范围内,对L1210细胞进行的流式细胞术研究表明,细胞周期的G2 / M期细胞蓄积,且百分比显着四倍体细胞(DNA含量为8N)。由于抑制微管蛋白聚合而产生的这种有趣的药理作用促使我们进行了初步的体内研究。
