exploration around three growing vectors born by this chemotype. Exploring this chemical space led to the identification of features to navigate G9a and DNMT1 biological spaces: not only their corresponding exclusive areas, selective compounds, but also common spaces. Thus, we identified from selective G9a and first-in-class DNMT1 inhibitors, >1 log unit between their IC50 values, with IC50 < 25 nM
表现出异常的酶活性或表达谱的表观遗传调节剂是癌症的潜在治疗靶标。具体而言,已在许多癌症中牵涉到负责组蛋白3赖氨酸9甲基化的酶(如G9a)和异常DNA高甲基化(DNMT)。最近,据报道带有4-氨基喹啉骨架的分子是这些靶标的双重抑制剂,并且在血液系统恶性动物模型中显示出显着的体内功效。在这里,我们报告了有关这种化学型出生的三种生长载体的详细探索。对这种化学空间的探索导致了导航G9a和DNMT1生物空间的特征的识别:不仅是它们相应的专有区域,选择性化合物,而且还有公共空间。因此,50个值,带IC 50 <25nM的(例如,43和26分别)与IC等效抑制剂50 <50nM的对两个靶(例如,13)。还报道了它们与某些癌细胞系相比的ADME / Tox分析和抗增殖功效。
