Aberrant regulation of N6-methyladenosine (m6A) RNA modification has been implicated in the progression of multiple diseases, including cancer. Previously, we identified a smallmoleculeinhibitor of the m6Ademethylase fat mass- and obesity-associated protein (FTO), which removes both m6A and N6,2′-O-dimethyladenosine (m6Am) RNA modifications. In this work, we describe the rational design and optimization
N 6 -甲基腺苷(m 6 A) RNA修饰的异常调节与包括癌症在内的多种疾病的进展有关。此前,我们发现了一种 m 6 A 去甲基化酶脂肪量和肥胖相关蛋白 (FTO)的小分子抑制剂,它可以去除 m 6 A 和N 6 ,2'- O -二甲基腺苷 (m 6 A m ) RNA 修饰. 在这项工作中,我们描述了一种新型 FTO 抑制剂的合理设计和优化,该抑制剂源自我们之前的先导 FTO-04,具有纳摩尔效力和对同源 m 6的高选择性RNA 去甲基化酶 ALKBH5。氧杂环丁烷类化合物包含 FTO 的竞争性抑制剂,在胶质母细胞瘤、急性髓性白血病和胃癌模型中具有有效的抗增殖作用,其中前导 FTO-43 显示出与临床化疗药物 5-氟尿嘧啶相当的效力。此外,FTO-43 增加 m 6 A 和 m 6 A m水平的方式与胃癌细胞中的 FTO 敲低和调节 Wnt/PI3K-Akt 信号通路相当。氧杂环丁烷基

A convenientsynthesis of 3-hydroxyquinolines has been described via unprecedented Dakin oxidation of quinoline-3-carboxaldehydes. Subsequently, application of the methodology to a high yielding synthesis of quinoline alkaloid Jineol (1) is reported.
