in human diseases such as colorectal cancer and Alzheimer’s disease, supporting the need to discover improved inhibitors, especially for use in models of neurodegeneration. Here, we have described the discovery and profile of 8l (ARUK3001185) as a potent, selective, and brain-penetrant inhibitor of Notum activity suitable for oral dosing in rodent models of disease. Crystallographic fragment screening
Notum 是一种羧酸酯酶,可通过 Wnt 蛋白上必需的棕榈油酸酯基团的脱酰化来抑制 Wnt 信号传导。人们越来越了解 Notum 在结直肠癌和阿尔茨海默氏病等人类疾病中所起的作用,支持发现改进的抑制剂的需要,特别是用于神经退行性疾病模型的抑制剂。在这里,我们描述了8l (ARUK3001185) 的发现和概况,它是一种有效的、选择性的、脑渗透性的 Notum 活性抑制剂,适合在啮齿动物疾病模型中口服给药。对 Diamond-SGC Poied 文库进行与 Notum 结合的晶体片段筛选,并通过生化酶测定对抑制活性进行排序,将6a和6b鉴定为一对出色的命中结果。 6的片段开发产生了8l ,在基于细胞的报告基因测定中,在 Notum 存在的情况下恢复了 Wnt 信号传导。药理学筛选评估显示8l对丝氨酸水解酶、激酶和药物靶点具有选择性。
