novel 4,9-dioxo-4,9-dihydro-1H-naphtho[2,3-d][1,2,3]triazol-3-ium salts, which can be viewed as analogs of cationic anthraquinones. Unlike the similar analogs that we have reported previously, these compounds show relatively weak antibacterial activities but exert strong anticancer activities (low μM to nM GI50), in particular, against melanoma, colon cancer, non-small cell lung cancer and central
我们合成了一系列新颖的4,9-二氧代-4,9-二氢-1 H-萘[2,3- d ] [1,2,3]三唑-3-鎓盐,可以将其视为类似物阳离子蒽醌。与我们之前报道的类似类似物不同,这些化合物显示出相对较弱的抗菌活性,但发挥了很强的抗癌活性(从低至μM到nM GI 50),尤其是针对黑色素瘤,结肠癌,非小细胞肺癌和中枢神经系统(CNS)癌症的治疗。这些化合物在结构上不同于其前身,因为它们具有直接连接到阳离子蒽醌骨架上的芳基而不是烷基链。对结构-活性关系(SAR)的进一步研究表明,芳环上的给电子取代基在通过共振效应增强抗癌活性方面具有重要作用。这些基团的立体位阻是不利的,但其影响不如共振效应。阳离子蒽醌类似物在N-1位的连接基团的差异是生物活性从抗菌药向抗癌药转换的主要结构因素。
