inhibitors including the cellular chemical probe UNC0638, which displays an excellent separation of functional potency and cell toxicity. However, this inhibitor is not suitable for animal studies due to its poor pharmacokinetic (PK) properties. Here, we report the discovery of the first G9a and GLP in vivo chemical probe UNC0642, which not only maintains high in vitro and cellular potency, low cell toxicity
在表观遗传的“写入器”、“读取器”和“擦除器”中,赖氨酸甲基转移酶 G9a 和 GLP 催化组蛋白 H3 赖氨酸 9 (H3K9me2) 和非组蛋白的单和二甲基化,已与多种人类疾病有关。一个由充分表征的化学探针组成的“工具包”将使有关这些蛋白质的生物学和疾病假设能够在基于细胞和动物模型中以高可信度进行测试。我们之前发现了有效且选择性的 G9a/GLP 抑制剂,包括细胞化学探针 UNC0638,它显示出功能效力和细胞毒性的出色分离。然而,由于其较差的药代动力学 (PK) 特性,该抑制剂不适合用于动物研究。在这里,我们报告了第一个 G9a 和 GLP 体内化学探针 UNC0642 的发现,
