生物活性

Acolbifene (EM-652), the active metabolite of EM800, is an orally active pure antiestrogen and selective estrogen receptor antagonist. Acolbifene (EM-652) inhibits estradiol (E2)-induced transcriptional activity of ERα (IC50 = 2 nM) and ERβ (IC50 = 0.4 nM). Acolbifene (EM-652) possesses potent and pure anticarcinogenic properties.

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 cancer cells (ZR-75-1, MCF-7, T-47D) and is devoid of any intrinsic estrogenic activity.

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.

The molarity calculator equation
Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)
The dilution calculator equation
Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2
