identification of cereblon modulator 3 (CC-885), with potent antitumor activity mediated through the degradation of GSPT1. We describe herein the structure-activity relationships for analogs of 3 with exploration of the structurally related dioxoisoindoline class. The observed activity of protein degradation could in part be rationalized through docking into the previously disclosed 3-CRBN-GSPT1 cocrystal
我们之前披露了 cereblon 调节剂 3 (CC-885) 的鉴定,其具有通过 GSPT1 降解介导的有效抗肿瘤活性。我们在此描述了 3 的类似物的结构-活性关系,并探索了结构相关的二氧代异二氢吲哚类。观察到的蛋白质降解活性可以通过与先前公开的 3-CRBN-GSPT1 共晶三元复合物对接来部分合理化。对于无法通过共晶复合体合理化的 SAR,我们试图通过内部开发的 QSAR 模型来预测 SAR。通过这些分析,可以在两种感兴趣的蛋白质 GSPT1 和 Aiolos 之间实现选择性蛋白质降解。
