PROTAC ERα Degrader-9

PROTAC ERα Degrader-9

• UNSPSC Description: PROTAC ERα Degrader-9 (Compound 18c) is a dual-targeting PROTAC degrader, which degrades estrogen receptor α (ERα) and aromatase (ARO). PROTAC ERα Degrader-9 binds to ERα with a Ki of 0.25 μM, inhibits ARO with an IC50 of 4.6 μM. PROTAC ERα Degrader-9 inhibits the proliferation of MCF-7 wildtype (IC50=0.54 μM) and ERα mutants MCF-7EGFR (IC50=0.075 μM), MCF-7D538G (IC50=0.31 μM), MCF-7Y537S (IC50=2.3 μM), downregulates the expressions of ERS1 and MYC. PROTAC ERα Degrader-9 arrests the cell cycle at G2/M, induces apoptosis in MCF-7. PROTAC ERα Degrader-9 exhibits antitumor efficacy in mouse models.
