0.4mg/ml Taking the 1 mL working solution as an example, add 20 μL of clarified DMSO stock solution of 20 mg/ml to 300 μL of PEG300, mix evenly to clarify it; add 20 μL of Tween80 to the above system, mix evenly to clarify it; then continue to add 660 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

生物活性

製品説明 フルベストラント (Fulvestrant (ICI-182780, ZD 9238, ZM 182780)) はエストロゲン受容体 (estrogen receptor, ER) アンタゴニストであり、cell-free assay における IC50 は 0.94 nM です。フルベストラントはまたオートファジー (autophagy) とアポトーシス (apoptosis) を誘導し、抗腫瘍活性を呈します。
in vitro Fulvestrant is an effective inhibitor of the growth of ER-positive MCF-7 (with IC50 of 0.29 nM) but with no effect on the growth of ER-negative BT-20 human breast cancer cells. Fulvestrant causes accumulation of cells in G0/G1 and also reduces the proportion of cells capable of continued DNA synthesis. [1] Fulvestrant competitively inhibits binding of oestradiol to the estrogen receptor. Fulvestrant blocks nuclear localization of the ER through impairing receptor dimerisation, and energy-dependent nucleo-cytoplasmic shuttling. Because of the instability of fulvestrant-ER complex, the binding of Fulvestrant with ER finally results in accelerated degradation of the ER protein. [2] Fulvestrant (10 nM) not only decreases IGF-IR mRNA levels but also decreases the half-life. [3] Treatment with 100 μM Fulvestrant leads to a time dependent increase of TNFR1 and TRADD steady-state mRNA levels in MCF-7 cells. [4] Fulvestrant is capable of down-regulating androgen receptor expression and diminishes androgenic responses in LNCaP human prostate cancer cells. Fulvestrant also significantly attenuates R1881-stimulated growth by 70%. [5] Fulvestrant is able to modulate mitosis and cell death in immature cerebellar neurons via rapid activation of MAPK. [6]
in vivo Fulvestrant is devoid of uterotropic activity, and when co-administered with estradiol, it effectively blocks the uterotropic action of estradiol with ED50 of 0.06 mg/kg/day s.c. in immature female rats. A single s.c. injection of 5 mg of Fulvestrant suspension blocks completely the growth of MCF-7 xenografts. The growth of transplants of the BrlO human breast tumor is also suppressed effectively by 10 μM Fulvestrant. [1] Fulvestrant (10 mg/rat, s.c.) reduces the androgen receptor expression, ERK1/2 phosphorylation and cell proliferation in the rat ventral prostate. [7] Fulvestrant also displays anti-angiogenesis in the chick egg chorioallantoic membrane. [8]

プロトコル(参考用のみ)

細胞アッセイ 細胞株 MCF-7 breast cancer cells
濃度 2.9 nM
反応時間 5 days
実験の流れ MCF-7 cells are cultured in multiwell plates (24-well, seeding density 4 × 104) in minimal essential medium containing phenol red, insulin (10 μg/mL), and 5% charcoal-stripped fetal calf serum without additional estradiol. Fulvestrant and/or estradiol are added in fresh medium 2 days after seeding. Cultures are maintained for 5 days with one further medium change and growth is assessed by measurement of total cell protein at the beginning and end of treatment and compared with that of controls treated with ethanol (0.1%) alone.
