BET BD2-IN-3 (compound I-58) 作为针对 BET BD2 结构域的抑制剂,有能力在小鼠身上展示外周器官和组织中的适宜生物分布。此化合物可通过 [11C] 进行放射性标记,并利用于正电子发射断层扫描 (PET) 成像技术。其在 PET 成像中的应用证明了其在生物学分布方面的有效性。
BRD4-BD1 2-IN-1 is a highly effective inhibitor of BRD4, specifically targeting the BRD4 BD-1 and BRD4 BD-2 domains with IC 50 values of <100 nM each (US20150148375A1, compound 5) [1].
GNE-987 is a highly active chimeric BET degrader. GNE-987 binds equipotently to the BD1 and BD2 bromodomains of BRD4 with low nanomolar affinities (IC50: 4.7 and 4.4 nM, respectively). GNE-987 exhibits picomolar cell BRD4 degradation activity (DC50: 0.03
