Target

IC50: 0.82 nM[1]

In Vitro CB1151 (0-100 nM; 5 days) inhibits MCF-7 cells growth, this cell proliferation is accessed by [3H]-thymidine incorporation, exhibits an IC50 value of 0.82 nM[1]. CB1151 (0-100 nM; 40 hours) exhibits activation of the IP9-type VD response element with a EC50 of 1.2 nM, the activation of IP9-type VD response elements shows a good correlation with inhibition of proliferation than the activation of DR3-type elements (EC50=3.2nM) in MCF-7 cells transfected with the CAT reporter[1]. CB1151 shows a functional dissociation constant (Kdf) value of 3.6 nM. The ligand concentration that provides 50% of protease-resistant VDR fragment is defined by Kdf, this is different from that of the traditional dissociation constant (Kd)[2]. Cell Proliferation Assay[1] Cell Line: MCF-7 cell Concentration: 0 nM; 0.1nM; 0.5nM; 0.8nM; 1nM; 5nM; 10 nM Incubation Time: 5 days Result: Inhibits MCF-7 cells growth.
