The synthesis and antitumor evaluation of a series of new heteroaromatic- and aromatic-substituted hydroxycyclohexadienones ("quinols"), and their imine counterparts, are described. The quinols were synthesized via the addition of a lithiated aromatic moiety to a quinone ketal followed by deprotection. When the aromatic portion of the molecule is a fused heterobicyclic structure (e.g., benzothiazole
描述了一系列新的杂芳族和芳族取代的羟基环己二酮(“喹诺尔”)及其亚胺对应物的合成和抗肿瘤评价。通过将锂化的芳族部分添加至醌缩酮,然后脱保护来合成喹诺醇。当分子的芳族部分是稠合的异双环结构(例如,苯并噻唑衍生物7a)时,在HCT 116(GI50 = 40 nM)和HT 29(GI50 = 380 nM)人结肠中也观察到了强大的体外抗肿瘤活性。作为MCF-7和MDA 468人乳腺癌细胞系。在NCI发育治疗药物筛选计划的体外筛选(60种人类癌细胞系)上进行检查时,该系列化合物中的活性化合物始终显示出高度不同寻常的选择性模式;细胞毒性(LC50)仅集中在某些结肠和肾细胞系中。类似物7a还显示了在裸NMRI小鼠中针对人RXF 944XL肾异种移植物的体内抗肿瘤活性,并且是进一步研究的焦点。
