生物活性:
Acolbifene (EM-652) hydrochloride, an active metabolite of EM800, is an orally active, cancer-preventing selective estrogen receptor modulator (SERM). Acolbifene (EM-652) hydrochloride inhibits estradiol (E2)-induced transcriptional activity of ERα (IC50=2 nM) and ERβ (IC50=0.4 nM). Acolbifene (EM-652) hydrochloride exerts a potent and pure antiestrogenic action in the mammary gland and uterus. Anticarcinogenic properties.

体内研究:
Acolbifene (ACOL) reduces food intake and strongly decreases cholesterolemia in rats fed a cholesterol-free diet.Acolbifene (ACOL) reduces food intake (16%) and weight gain (45%, mainly fat) similarly in both dietary cohorts.Animal Model:Female Sprague-Dawley rats (n = 42) initially weighing 175-200 g.
Dosage:2.5 mg/kg.
Administration:Oral gavage, once daily for 21 d.
Result:Prevents tumor growth in rats.

体外研究:
Acolbifene (ACOL) does not affect pathways of cholesterol synthesis, supporting the involvement of the clearance-related receptors in its hypocholesterolemic action.Acolbifene (EM-652) shows no agonistic activity on ERα and ERβ transcriptional function and blocks the estradiol (E2)-mediated activation of both ERα and ERβ.Acolbifene (EM-652) shows the most potent inhibition of estradiol-stimulated cell proliferation in human breast cancer cells (ZR-75-1, MCF-7, T-47D) and is devoid of any intrinsic estrogenic activity.
