G-quadruplexes are unusual structures formed from guanine-rich sequences of nucleic acids. G-quadruplexes have been postulated to play important roles in a number of biological systems including gene regulation and the inhibition of enzyme function. Recently, our laboratory reported on the synthesis and evaluation of a triaza-cyclopentaphenanthrene compound which bound to G-quadruplexes with good affinity
G-四链体是由富含鸟嘌呤的核酸序列形成的异常结构。已经假定G-四链体在许多生物系统中起重要作用,包括基因调控和酶功能抑制。最近,我们的实验室报道了合成并评价具有良好亲和性和选择性的G-四链体的Triaza-cyclopentaphenanthrene化合物的合成和评价。该化合物含有一个4-吡啶酮基团,该基团以前没有用于其他四链体结合剂中。在这封信中,我们描述了含有2-和3-羧基-苯并喹啉作为G-四链体结合剂的4-吡啶酮的合成和评价。我们发现这些化合物能够与K a在3×10 5范围内的G-四链体结合。 M -1且对四链体的选择性是双链体DNA的10倍。
