Elacestrant (RAD1901) is an orally available and selective estrogen receptor degrader (SERD) with IC 50 s of 48 and 870 nM for ERα and ERβ, respectively. Elacestrant also can inhibit growth of ER breast cancer cell lines in vitro and in vivo.

IC50: 48 nM (ERα), 870 nM (ERβ)
体外研究(In Vitro)
Elacestrant (RAD1901; 0.5 nM-10 μM; 48 h) 在 MCF-7 细胞中,以浓度依赖的方式抑制 ERα 的表达 (EC50 = 0.6 nM)。Elacestrant (0-1 μM; 48 h) 以浓度依赖的方式对雌二醇 (E2) 刺激的 ER 阳性 MCF-7 细胞显示出抗增殖活性 (EC50 = 4 pM) 。Elacestrant (0-1 μM; 24 or 48 h) 在 MCF7, T47D 和 HCC1428 细胞中,抑制雌激素受体蛋白的表达。Elacestrant (0.01, 0.1, 1.0 μM) 能降低 MCF7 和 T47D 细胞系中孕酮受体 (PGR、PR; 一种 ER 靶基因) 的表达。 has not independently confirmed the accuracy of these methods.

体内研究(In Vivo)
Elacestrant (0.3-120 mg/kg; p.o.; single daily for 40 days) 在大鼠中以剂量依赖的方式拮抗 E2 介导的子宫刺激。
Elacestrant (30, 60 mg/kg; p.o.; single daily for 4 weeks) 在小鼠体内完全抑制肿瘤生长。
Elacestrant 在停药后,还能持续四周抑制肿瘤生长. has not independently confirmed the accuracy of these methods. They are for reference only.
