Novel polyamine transport inhibitors have been synthesized and demonstrated to block the uptake of native polyamines into human cancer cells. A combination therapy of the transport inhibitor and DFMO (a drug which blocks polyamine biosynthesis) provided synergistic activity against a metastatic human colon cancer cell line. The strategy uses polyamine depletion and polyamine metabolism to generate reactive oxygen species within cells as a novel way to treat cancers. This approach may be implemented for widespread use in the treatment of diseases which rely upon polyamine transport activity for proliferation.
新型聚胺运输
抑制剂已经合成并证明可以阻止天然聚胺进入人类癌细胞。运输
抑制剂和DFMO(一种阻止聚胺
生物合成的药物)的联合治疗对转移性人类结肠癌
细胞系表现出协同作用。该策略利用聚胺耗竭和聚胺代谢在细胞内产生活性氧自由基的新方法来治疗癌症。这种方法可以在依赖聚胺运输活性进行增殖的疾病的广泛治疗中实施。
