CB1151 是 1,25 二羟基维生素D3 (VD) 的 20 表位类似物 ( 20-epi analogue of VD)，具有有效的抗肿瘤作用。CB1151 抑制 MCF-7 细胞生长， IC₅₀ 值为 0.82 nM。

CB1151 is a 20-epi analogue of 1,25 dihydroxyvitamin D3 (VD) with potent anti-tumor effects. CB1151 inhibits MCF-7 cell growth with an IC 50 value of 0.82 nM.

Solid

IC50: 0.82 nM

CB1151 (0-100 nM; 5 days) inhibits MCF-7 cells growth, this cell proliferation is accessed by [H]-thymidine incorporation, exhibits an IC50 value of 0.82 nM.
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.
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).
