Biological Activity

[Description]:

Estrogen receptor modulator 1 (compound 18) is an orally active and selective estrogen receptor modulator (SERM), with a pIC50 of 0.46. Estrogen receptor modulator 1 induces regression of Tamoxifen-resistant, hormone independent xenograft tumors[1][2].

[In Vitro]

Estrogen receptor modulator 1 (compound 18) (100 nM; 10 days) inhibits T47D:A18/PKCα and T47D:A18-TAM1 colony formation[2]. Estrogen receptor modulator 1 (100 nM; 9 days) significantly inhibits the growth of MCF-7:5C cell, and induces apoptosis in these cells 6 days[2]. Cell Proliferation Assay[2] Cell Line: T47D:A18/PKCα and T47D:A18-TAM1 cells Concentration: 100 nM Incubation Time: 10 days Result: Inhibit T47D:A18/PKCα and T47D:A18-TAM1 colony formation. Cell Viability Assay[2] Cell Line: MCF-7:5C cells Concentration: 100 nM Incubation Time: 9 days Result: Significantly inhibited the growth of MCF-7:5C cells.

[In Vivo]

Estrogen receptor modulator 1 (1.5 mg/animal; p.o. ; daily for 2 weeks) results in regression of T47D:A18/PKCα tumors[2]. Animal Model: 4-6 week old athymic mice (Harlan-Sprague-Dawley)[2] Dosage: 1.5 mg/animal Administration: p.o. ; daily for 2 weeks Result: Significantly reduced tumor volume.
