BSJ-03-204 triTFA is a PROTAC connected by ligands for Cereblon and CDK. BSJ-03-204 triTFA is a potent and selective Palbociclib-based CDK4/6 dual degrader (PROTAC), with IC50s of 26.9 nM and 10.4 nM for CDK4/D1 and CDK6/D1, respectively. BSJ-03-204 triTFA does not induce IKZF1/3 degradation and has anti-cancer activity.
BSJ-03-204 triTFA (0.0001-100 μM; for 3 or 4 days) has potent anti-proliferative effects on MCL cell lines[1]. BSJ-03-204 triTFA (1 μM; for 1 day) potently induces a G1 arrest[1]. BSJ-03-204 triTFA (0.1-5 μM; for 4 hours) only resultes in degradation of CDK4/6 in WT cells, not IKZF1/3[1].
