the N2-substituted fused pyrazolo series, which was validated by biophysical methods. Structure-based drug design efforts along with optimization of cellular potency and ADME ultimately led to the identification of RP-6685: a potent, selective, and orally bioavailable Polθ inhibitor that showed in vivo efficacy in an HCT116 BRCA2–/– mouse tumor xenograft model.
DNA 聚合酶 theta (Polθ) 是一种有吸引力的药物发现合成致死靶标,预计可有效对抗含有 BRCA 突变等位基因的乳腺癌和卵巢癌。在这里,我们描述了我们在寻找人类 Polθ(由 POLQ 编码)的选择性抑制剂方面所做的努力。对 350,000 种化合物进行的高通量筛选活动鉴定出 11 微摩尔的化合物,产生了 N2 取代的稠合吡唑并系列,并通过生物物理方法进行了验证。基于结构的药物设计工作以及细胞效力和 ADME 的优化最终导致了RP-6685的鉴定:一种有效的、选择性的、口服生物可利用的 Polθ 抑制剂,在 HCT116 BRCA2 –/–小鼠肿瘤异种移植模型中显示出体内功效。
