A ring in the structure of tubulin polymerization inhibitors. In our search to identify more potent inhibitors, a study of different isosteric tricyclic groups as new potential A rings was first realized and permitted to identify 1-azaphenothiazine and iminodibenzyl as favorable modulations providing compounds with improved activity against tubulin. An investigation of the methylene group as the connector
在微管蛋白聚合抑制剂的结构中,吩噻嗪基已被确定为合适的A环。在寻找更有效的抑制剂的研究中,首次实现了对不同的立体三环基团作为新的潜在A环的研究,并允许将1-氮杂吩噻嗪和亚氨基二苄基鉴定为有利的调节方式,从而为化合物提供了改善的抗微管蛋白活性。对亚甲基作为A和B环之间的连接基的研究表明,当A单元是吩噻嗪,1-氮杂吩噻嗪或亚氨基二苄基类型时,“ CH 2 ”桥是可以耐受的,从而提高了生物效力。分子6 – 8和12与亲本phenstatin 2相比,在COLO 205结肠癌细胞系中显示出更高的生物活性。当前研究中最抗肿瘤的药物是吩噻嗪5,对黑素瘤MDA-MB-435细胞系的GI 50为25 nM。
