因多昔芬盐酸盐 T6827L

Product Introduction
Bioactivity


英文名: Endoxifen hydrochloride

描述: Endoxifen hydrochloride，Tamoxifen的主要活性代谢产物，具备较高的对雌激素受体(estrogen receptor)的亲和力和特异性，并能抑制芳香酶活性。它在乳腺癌研究中表现出潜在应用价值。

体外活性: Endoxifen, an hydroxylated metabolite of Tamoxifen, exhibits approximately 100-fold greater potency as an estrogen receptor (ER) antagonist compared to tamoxifen. Furthermore, it indicates that endoxifen, unlike 4-hydroxytamoxifen, induces degradation of ER-alpha in breast cancer cells in addition to its transcriptional effects on the ER.[1] Endoxifen acts as a potent antiestrogen that promotes the degradation of estrogen receptor α in breast cancer cells. Additionally, it has been demonstrated that endoxifen hinders ERA transcriptional activity and effectively suppresses estrogen-induced proliferation of breast cancer cells, even in the presence of tamoxifen, N-desmethyl-tamoxifen, and 4-hydroxytamoxifen.[2] Endoxifen exhibits significant growth inhibition at a concentration of 10 μM for all breast cancer cell lines, except for MDAMB-468, which shows moderate inhibition. At a concentration of 10 μM, cytotoxic effects are particularly prominent in MCF7, HS 578T, and BT-549 cells. In contrast, lower concentrations of Endoxifen (0.01-1 μM) result in less significant inhibitory effects compared to 10 μM. However, a concentration of 100 μM of Endoxifen is found to be lethal for all tested cells.[2]

体内活性: Endoxifen, when administered orally, is quickly absorbed and readily enters systemic circulation. Administering oral Endoxifen once daily for 28 consecutive days, at dosages of 2, 4, and 8 mg/kg, has demonstrated safety and progressive inhibition of human mammary tumor xenograft growth in female mice.[2]
