ERD-308 induces >95% of ER degradation at concentrations as low as 5 nM in both cell lines (DC50 (concentration causing 50% of protein degradation) of 0.17 nM and 0.43 nM in MCF-7 and T47D ER+ cells, respectively).ERD-308 is a highly potent PROTAC degrade
PROTAC CDK9 degrader-2 (compounds 11c) is a potent and selective CDK9 degrader based on PROTAC, with an IC50 of 17 μM in MCF-7 cell lines. Natural product Wogonin binds ubiquitin E3 ligase cereblon (CRBN) via a linker to form PROTAC[1].
