reported several quinazoline derivatives [17]. These compounds could mimic a tetracyclic aromatic system through intramolecular hydrogen bond. Studies showed that these quinazoline derivatives were effective and selective telomeric G-quadruplex ligands. With this encouragement, here we synthesized a series of N-(2-(quinazolin-2-yl)phenyl)benzamide (QPB) compounds as modified quinazoline derivatives. In
为了提高吲哚喹啉或苯并呋喃喹啉衍生物的选择性,我们先前报道了几种喹唑啉衍生物[17]。这些化合物可通过分子内氢键模拟四环芳族系统。研究表明,这些喹唑啉衍生物是有效的和选择性的端粒G-四链体配体。在这种鼓励下,我们在此合成了一系列N-(2-(喹唑啉-2-基)苯基)苯甲酰胺(QPB)化合物,作为修饰的喹唑啉衍生物。在该变型中,将苯基引入芳族核。评价结果表明,部分QPB衍生物对端粒G-四链体DNA的结合能力强于LZ-11。,是已报道的喹唑啉衍生物中最有潜力的化合物。此外,研究了端粒酶抑制QPB衍生物及其细胞效应。
