| Hazard Information | Back Directory | [Uses]
Elacestrant (RAD1901) dihydrochloride is an orally available and selective estrogen receptor degrader (SERD) with IC50s of 48 and 870 nM for ERα and ERβ, respectively. Elacestrant dihydrochloride also can inhibit growth of ER+ breast cancer cell lines in vitro and in vivo[1][2]. | [in vivo]
Elacestrant dihydrochloride (0.3-120 mg/kg; p.o.; single daily for 40 days) antagonizes E2-mediated uterine stimulation in a dose-dependent manner in vivo[1].
Elacestrant dihydrochloride (30, 60 mg/kg; p.o.; single daily for 4 weeks) induces complete tumor growth inhibition in mice[2].
Tumor growth inhibition is maintained for 4 weeks after Elacestrant dihydrochloride withdrawal[2]. | Animal Model: | MCF7 cell line xenograft model of mice[2]. | | Dosage: | 30, 60 mg/kg | | Administration: | Oral administration; single daily for 4 weeks. | | Result: | Inhibited growth of tumor. |
