Polyamine compounds, method of synthesis and method of use for anti-cancer purposes, and for enhancing the activity of existing anti-cancer drugs are provided. This disclosure has identified certain polyamine motifs that can be attached to toxic agents to facilitate their access to cancer cells as well as polyamine compounds of surprising cytotoxicity and selectivity in killing cancer cells. It includes an illustrative conjugate system with examples of a triamine or a tetraamine appended to a cytotoxic agent. There are five method schemes illustrative of the synthesis of the compounds of the invention. Included is a general strategy to enhance cell uptake by attaching a polyamine vectoring system with an example of a triamine vector attached to an existing anti-cancer drug to improve its chemotherapeutic potency. There is an illustration of using the triamine vector to improve the selectivity of an anthracenylmethyl amine cytotoxic agent (e.g. an anthracenylmethyl-4,4-triamine conjugate outperformed an anthracenylmethyl N-butyl amine derivative). There is an illustration of a synthetic method to attach the polyamine vector onto an existing chemotherapeutic, doxorubicin. This methodology can lead to the synthesis of the polyamine-doxorubicin conjugate. There are illustrations of the synthesis of various alkyl aryl substituted polyamines, a hydroxylated polyamine derivative and a cyclohexyldiamine analogue.
提供了聚胺化合物、用于抗癌目的的合成方法和使用方法,以及用于增强现有抗癌药物活性的方法。本公开揭示了可以附着在毒性剂上的某些聚胺基团,以促进它们进入癌细胞,以及在杀灭癌细胞方面具有惊人细胞毒性和选择性的聚胺化合物。其中包括具有三胺或四胺附加到细胞毒性剂的示例的插图结合系统。有五种示例性的方法方案说明了本发明化合物的合成。其中包括通过附着聚胺引导系统来增强细胞摄取的一般策略,其中包括将三胺引导附着到现有抗癌药物以提高其化疗效力的示例。有一个示例说明了使用三胺引导来提高蒽甲基胺类细胞毒性剂的选择性(例如,蒽甲基-4,4-三胺共轭物优于蒽甲基N-丁基胺衍生物)。还有一个示例说明了一种合成方法,用于将聚胺引导附着到现有的化疗药物多柔比星上。这种方法可以导致聚胺-多柔比星共轭物的合成。还有合成各种烷基芳基取代的聚胺、羟基化聚胺衍生物和环己基二胺类似物的插图。
