Acolbifen (EM-652)-Hydrochlorid, ein aktiver Metabolit von EM800, ist ein oral aktiver, krebsvorbeugender selektiver Östrogenrezeptor-Modulator (SERM). Acolbifen (EM-652)-Hydrochlorid hemmt die Östradiol (E2)-induzierte TranskriptionsaktivitÄt von ERα (IC50 = 2 nM) und ERβ (IC50 = 0,4 nM). Acolbifen (EM-652)-Hydrochlorid Übt eine starke und reine antiÖstrogene Wirkung in der BrustdrÜse und im Uterus aus. Antikarzinogene Eigenschaften.

Acolbifene (EM-652) hydrochloride, the active metabolite of EM800, is an orally active pure antiestrogen and selective estrogen receptor antagonist with an IC50 of of 0.110 nM in T-47D cells. Acolbifene (EM-652) hydrochloride possesses potent and pure anticarcinogenic properties[1][2].
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 cells (ZR-75-1, MCF-7, T-47D) and is devoid of any intrinsic estrogenic activity[4].
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]. Animal Model: Female Sprague-Dawley rats (n = 42) initially weighing 175-200 g[2].
