生物活性

Fulvestrant是一种Estrogen receptor（ER）（雌激素受体）拮抗剂， IC50为0.094 nM。Fulvestrant 有效抑制ER阳性的MCF-7生长(IC50为 0.29 nM)，而对ER阴性的的 BT-20人类乳腺癌细胞的生长没有作用效果。Fulvestrant 使细胞在 G0/G1 期累积，也降低了能持续进行DNA合成的细胞比例。 Fulvestrant 竞争性地抑制雌二醇与雌激素受体结合。

细胞实验
细胞系	MCF-7
方法	MCF-7 cells were plated at 10 000 cells/well in 96-well culture plates in MEM with 10% fetal bovine serum, and they were allowed to adhere for 48 h. Thereafter, the cultures were washed with serum-free MEM and incubated in 100 μl serum-free MEM. After 72 h, the medium was removed and replaced with 2% charcoal-stripped FBS–MEM containing 10 pmol/l E2 with either RAD1901 or additional E2 at concentrations ranging from 10–15 to 10–6 mol/l. The medium was removed after 48 h of incubation and the cells were lysed by adding 100 μl of CellTiter Glo (Promega, Madison, Wisconsin, USA), diluted 1 : 1 in water, per well. The plates were gently mixed on a plate shaker for 10 min before the luminescent signal was measured on a luminometer. The EC50 and IC50 of the test compound were defined as the concentrations that resulted in half-maximum shift.

不同实验动物依据体表面积的等效剂量转换表（数据来源于FDA指南）

	小鼠	大鼠	兔	豚鼠	仓鼠	狗
重量 (kg)	0.02	0.15	1.8	0.4	0.08	10
体表面积 (m2)	0.007	0.025	0.15	0.05	0.02	0.5
Km系数	3	6	12	8	5	20

动物 A (mg/kg) = 动物 B (mg/kg) ×	动物 B的Km系数
	动物 A的Km系数

例如，依据体表面积折算法，将化合物用于小鼠的剂量20 mg/kg 换算成大鼠的剂量，需要将20 mg/kg 乘以小鼠的K_m系数（3），再除以大鼠的K_m系数（6），得到化合物用于大鼠的等效剂量为10 mg/kg。
