protac erα degrader 2

PROTAC ERα Degrader-2 comprises a cIAP1 ligand binding group, a linker and an estrogen receptor α (ERα) binding group. PROTAC ERα Degrader-2 is an ERα degrader. Maximal ERα degradation at 30 μM concentration in human mammary tumor MCF7 cells. Degradation inducers based on cIAP1 are called specific and non-genetic IAP-dependent protein erasers (SNIPERs)[1].

PROTAC ER Degrader-2 serves as a synthesis intermediate for the production of PAC, a compound that incorporates the ADCs linker and PROTACs, which are subsequently conjugated to an antibody. PAC, exhibits a greater capability to degrade estrogen receptor-alpha (ERα) compared to PROTAC (without the presence of an antibody)[1].
