Cat. No. Product Name Effect Purity
  • HY-125263
    OP-1074
    		Degrader 99.77%
    OP-1074, a pure anti-estrogen drug, is a selective ER degrader (PA-SERD) with specific anti-estrogenic activity against ERα and ERβ, inhibiting 17β-estradiol (E2)-stimulated transcription with IC50 values of 1.6 and 3.2 nM, respectively.
  • HY-149295
    PROTAC ERα Degrader-4
    		Degrader 98.63%
    PROTAC ERα Degrader-4 is a highly potent and selectivePROTAC ERα degrader (Ki: 5.08 μM). PROTAC ERα Degrader-4 contains OBHSAs, linker and E3 ligase ligands. PROTAC ERα Degrader-4 shows excellent cell inhibitory and ERα degradation activity against Tamoxifen-sensitive and -resistant ER+ breast cancer (BC) cells and ERα-mutated BC cells. PROTAC ERα Degrader-4 can induce apoptosis and can be used for cancer research.
  • HY-163679
    PROTAC ERα Degrader-9
    		Degrader
    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. (Pink: ligand for target protein (HY-163680); Black: linker (HY-W007559); Blue: ligand for E3 ligase (HY-112078))
