Biological target:
Droloxifene citrate is an Antineoplastic.
In vitro activity:
DROL (droloxifene) dose-dependently inhibited the E2-induced stimulation of growth of these cells in medium without phenol red, but TAM inhibited the growth only at high concentrations. Reference: Jpn J Pharmacol. 1993 Sep;63(1):27-34. https://pubmed.ncbi.nlm.nih.gov/8271528/
In vivo activity:
Pregnant rats were treated orally with droloxifene at 10:00 AM on d 2 at doses of 1.25-20 mg/kg to observe anti-implantation effects, and then doses of 14 mg/kg or 2.5 mg/kg were given at different time on d 2 to d 5 to determine the optimal administration time for anti-implantation effects. Pregnant rats were treated with a combination of droloxifene (2.5 mg/kg, ig) and E2 (0.5-8.0 microg/kg, sc) on the optimal administration time to observe the antagonistic effect of external estrogen on the anti-implantation effect of droloxifene. Droloxifene has anti-implantation effects in rats. Reference: Acta Pharmacol Sin. 2005 Oct;26(10):1243-7. https://pubmed.ncbi.nlm.nih.gov/16174441/
