corresponding 6-chloro derivative with a suitable omega-aminoalkylamine. The noncovalent DNA-binding properties of these compounds have been examined using a fluorometric technique. In vitro cytotoxic potencies of these derivatives toward eight tumor cell lines, including human colon adenocarcinoma (HT29, LoVo sensitive and LoVo/Dx (doxorubicin-resistant)) and human ovarian carcinoma (A2780 sensitive, A2780cisR
通过以下方法制备了一系列可插入DNA的潜在抗肿瘤药:(氨基)烷基取代的2,3-二氢-1H,7H-嘧啶基[5,6,1-de] ac啶-1,3,7-三酮。相应的6-氯衍生物与合适的ω-氨基烷基胺进行氨解。这些化合物的非共价DNA结合特性已使用荧光技术进行了检查。这些衍生物对八种肿瘤细胞系的体外细胞毒性潜能,包括人结肠腺癌(HT29,LoVo敏感和LoVo / Dx(对阿霉素耐药))和人卵巢癌(对A2780敏感,对A2780cisR(对顺铂耐药),CH1,CH1cisR描述了顺铂(顺铂耐药)和SKOV-3细胞,并将其与参考药物进行了比较。对于几乎所有目标化合物,其细胞毒活性通常与观察到的DNA亲和力平行。已经发现有趣的结构-活性关系。还计算了辛醇/水分配系数,但与细胞毒性值或抗药性指数均无关。已鉴定出三种具有高度DNA亲和力的类似物9和15f,15h,具有广泛的细胞毒性活性。
