恶性细胞表现出增加的电负性。 线粒体膜 癌细胞中的电位高于正常上皮细胞。 这可能是 至少部分地导致亲脂性阳离子化合物 选择性地在癌细胞中积聚。 我们建议综合和 评价新型阳离子(+)- YW-200前药。(+)-YW-200是一种新的 CC-1065是迄今为止发现的最有效的抗癌药物之一。 YW-200是 1000-对不同肿瘤细胞系的效力比阿霉素高出1倍, 并且在体内显示出显著的抗肿瘤活性, 骨髓抑制,其他CC-1065类似物的剂量限制性毒性。新 阳离子(+)-YW-200前药将是水溶性的,可被 癌细胞,并因此具有改善的治疗指数。 拟定商业应用: 这些新化合物可用作抗癌药物。
英文摘要
Malignant cells exhibit increased electronegativity. The mitochondrial membrane potential is higher in carcinoma cells than in normal epithelial cells. This may be at least partially responsible for the fact that lipophilic cationic compounds selectively accumulate in carcinoma cells. We propose to synthesize and evaluate novel cationic (+)- YW-200 prodrugs. (+)-YW-200 is a new analog of CC-1065, one of the most potent anticancer drug discovered to date. YW-200 is 1000-fold more potent than doxorubicin against different tumor cell lines in vitro and shows remarkable antitumor activity in vivo without causing myelosuppression, the dose-limiting toxicity of other CC-1065 analogs. The new cationic (+)-YW-200 prodrugs will be water-soluble, selectively taken-up by cancer cells, and thus have an improved therapeutic index. PROPOSED COMMERCIAL APPLICATION: These novel compounds can be used as anticancer drugs.
