amines at the 3- and 8-positions of ethidium bromide into guanidine, pyrrole, urea, and various substituted ureas. The resulting derivatives exhibit unique spectral properties that change upon binding nucleic acids. The compounds were analyzed for their ability to inhibit the HIV-1 Rev-Rev Response Element (RRE) interaction, as well as for their affinity to calf thymus DNA. One derivative (3,8-bis-ure
通过将溴化乙锭的3-位和8位上的胺转化为胍,吡咯,尿素和各种取代的脲,已经合成了一系列取代的菲啶衍生物。所得的衍生物表现出独特的光谱性质,该光谱性质在结合核酸时发生变化。分析了这些化合物抑制HIV-1 Rev-Rev反应元件(RRE)相互作用的能力,以及它们与小牛胸腺DNA的亲和力。与溴化乙锭相比,一种衍生物(3,8-双脲-乙二胺-5-乙基-6-苯基菲啶三氟乙酸盐)对HIV-1 RRE的亲和力和特异性更高。这些结果表明,嵌入剂的核酸亲和力和特异性可以通过其环外胺的合成修饰来调节。
