several small molecule inhibitors have been described in the literature, their cellular activity has proved to be underwhelming. In this work, we describe the identification of a novel series of ATAD2 inhibitors by high throughput screening, confirmation of the bromodomain region as the site of action, and the optimization campaign undertaken to improve the potency, selectivity, and permeability of the
ATAD2 是一种表观遗传的含溴结构域的靶标,在许多癌症中过度表达,并已被建议作为潜在的肿瘤学靶标。虽然文献中已经描述了几种小分子抑制剂,但它们的细胞活性已被证明是平淡无奇的。在这项工作中,我们描述了通过高通量筛选鉴定一系列新的 ATAD2 抑制剂,确认溴域区域作为作用位点,以及为提高初始命中的效力、选择性和渗透性而进行的优化活动。结果是化合物5 (AZ13824374),一种高效和选择性的 ATAD2 抑制剂,在一系列乳腺癌模型中显示出细胞靶标参与和抗增殖活性。
