contains a guanine-rich sequence in the 5′-untranslated regions (5′-UTR) of the mRNA that could form an RNA G-quadruplex structure. This structure acts as a repressor for NRAS translation and could be a potential target for anticancer drugs. Our previous studies found an effective scaffold, the quindoline scaffold, for binding and stabilizing the DNA G-quadruplex structures. Here, on the basis of the
人类原癌基因神经母细胞瘤RAS(NRAS)在mRNA的5'非翻译区(5'-UTR)中含有富含鸟嘌呤的序列,可以形成RNA G四联体结构。该结构可作为NRAS翻译的阻遏物,并可能成为抗癌药物的潜在靶标。我们以前的研究发现了一种有效的支架,喹啉支架,可以结合并稳定DNA G-四链体结构。在此,根据先前的研究和已报道的RNA特异性探针,设计,合成了一系列新型的对-(甲硫基)苯乙烯基取代的喹啉(MSQ)衍生物,并评估为NRASRNA G-四链体配体。实验小组证明对-(甲硫基)苯乙烯基侧链的引入可以增强与NRAS RNA G-四链体的特异性结合。其中一则热门歌曲(4a-10)对G四联体表现出强大的稳定活性,随后抑制了NRAS的翻译并抑制了肿瘤细胞的增殖。我们的发现提供了一种新颖的策略,可通过特异性结合mRNA的5'-UTR中的RNA G-四链体来发现新颖的NRAS阻遏物。
