描述 | ARV-825 is a PROTAC targeting on BRD4, consisting of a BRD4-ligand JQ-1 linked to a cereblon E3 ligase ligand Pomalidomide, with Kds values of 90nM and 28nM for affinity to BD1 and BD2. ARV-825 led to a fast and efficient degradation of BRD4 at concentration ranging in 1-300nM in Namalwa and CA-46 cells and a dose-dependent degradation of BRD4 post 1-24h in Namalwa and Ramos cells exposure to 100nM ARV-825. Also, it led to a more significant c-MYC suppression than JQ1 or OTX015 by depletion of BRD4 by ARV-825 at different concentration (0.1, 0.3 and 1μM) or time point (2-24h), as well as a longer lasting effect after washout (6, 24h). Consistent with this downregulation of c-MYC, ARV-825 achieved a superior effect on suppression of BL cell proliferation and apoptosis induction compared with JQ1 or OTX015, including Namalwa, CA-46, Ramos and DAUDI cell lines[1]. |
