fulvestrant

Fulvestrant (ZM 182780) is an estrogen receptor (ER) antagonist (IC50=9.4 nM) and an agonist of GPR30. Fulvestrant has antitumor activity, inhibiting cell proliferation and inducing apoptosis and autophagy.

Fulvestrant R enantiomer is the less active R enantiomer of Fulvestrant. Fulvestrant is a potent estrogen receptor antagonist with an IC50 of 9.4 nM.

Fulvestrant S enantiomer is the less active S enantiomer of Fulvestrant. Fulvestrant is a potent estrogen receptor antagonist with an IC50 of 9.4 nM.

Fulvestrant sulfone is a synthetic estrogen receptor antagonist.

Fulvestrant 3-β-D-Glucuronide, a glucuronide and sulfate conjugate metabolite of the pure anti-estrogenic steroid Fulvestrant, is utilized in breast cancer research [1].

Fulvestrant-d3 is a isotope labeled compound of Fulvestrant.Fulvestrant (ZM 182780) is an estrogen receptor (ER) antagonist and GPR30 agonist that inhibits cell proliferation and induces apoptosis and autophagy.

BY13 is an SRC-3 PROTAC degrader with a DC50 of 0.031 μM. It selectively obstructs the ER signaling pathway by downregulating ERα levels, showing greater selectivity over the androgen receptor (AR). BY13 effectively addresses endocrine resistance in breast cancer by inducing cell cycle arrest at the G1 phase and triggering apoptosis. Additionally, it surpasses Fulvestrant in efficacy and significantly inhibits the growth of resistant breast tumors in LCC2 xenograft mouse models, exhibiting no noticeable toxicity.

Endoxifen, also known as N-desmethyl-4-hydroxytamoxifen, is a chemical that is under development for estrogen receptor-positive breast cancer. It is also being evaluated as an antipsychotic for treatment of mania and other psychotic disorders. Endoxifen is a nonsteroidal selective estrogen receptor modulator (SERM) of the triphenylethylene group. It is an active metabolite of tamoxifen and has been found to be effective in patients that have failed previous hormonal therapies (tamoxifen, aromatase inhibitors, and fulvestrant). The prodrug tamoxifen is metabolized by the CYP2D6 enzyme to produce afimoxifene (4-hydroxytamoxifen) and endoxifen.
