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.

ERβ

0.4 nM (IC₅₀, E2-induced transcriptional activity)

Cellular Effect

Cell Line	Type	Value	Description	References
ZR-75-1	IC₅₀	0.55 nM Compound: (S)-6 (EM-652)	Inhibition of estradiol-stimulated ZR-75-1-cell proliferation Inhibition of estradiol-stimulated ZR-75-1-cell proliferation	[PMID: 9216828]

In Vitro

Acolbifene (ACOL) does not affect pathways of cholesterol synthesis, supporting the involvement of the clearance-related receptors in its hypocholesterolemic action^[2].
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^[3].
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^[4].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

Acolbifene (ACOL) reduces food intake and strongly decreases cholesterolemia in rats fed a cholesterol-free diet^[2].
Acolbifene (ACOL) reduces food intake (16%) and weight gain (45%, mainly fat) similarly in both dietary cohorts^[2].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model:	Female Sprague-Dawley rats (n = 42) initially weighing 175-200 g^[2].
Dosage:	2.5 mg/kg.
Administration:	Oral gavage, once daily for 21 d.
Result:	Prevents tumor growth in rats.

Help & FAQs

Do most proteins show cross-species activity?
Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
