A method of using modified xanthine molecules as a binding agent is disclosed. Xanthine molecules with at least one substitution of a methyl group at the N1, N3, N7, or N9 position bind to intercalating molecules efficiently. This method can be applied to inhibiting intercalating molecules from binding to nucleic acids, as well as removing intercalating molecules that have been bound to nucleic acids. This method can also be applied to synthesize an efficient drug delivery system for compounds that have low solubility in aqueous media, including anti-neoplastic agents. The method can also be applied to flurosecently labeling nucleic acids.
本研究公开了一种使用改性
黄嘌呤分子作为结合剂的方法。在 N1、N3、N7 或 N9 位上至少有一个甲基被取代的
黄嘌呤分子能有效地与插层分子结合。这种方法可用于抑制插层分子与核酸结合,以及去除已与核酸结合的插层分子。这种方法还可用于合成一种高效的药物输送系统,用于输送在
水介质中溶解度低的化合物,包括
抗肿瘤药物。该方法还可用于对核酸进行荧光标记。
