| Description | Inecalcitol (TX 522), a unique vitamin D3 analog, is an orally active vitamin D receptor (VDR) agonist with a Kd of 0.53 nM. Inecalcitol can induce cell apoptosis and has potent anticancer activities[1][2][3][4]. |

| Target |
Kd: 0.53 nM (vitamin D receptor (VDR))[2] |
| In Vitro | Inecalcitol (0.1-10 nM; 48 hours) treatment of LNCaP cells results in decreased expression of both protein and mRNA of Pim-1 in a dose-dependent manner. Inecalcitol (0.1-10 nM; 48 hours) also decreases ETV1 expression levels in a dose-dependent manner[1]. Inecalcitol (10-14 days) inhibits the growth of LNCaP and HL-60 cells with ED50 values of 4.0 nM and 0.28 nM, respectively[1]. Western Blot Analysis[1] Cell Line: LNCaP cells Concentration: 0.1 nM, 1 nM, 10 nM Incubation Time: 48 hours Result: Resulted in decreased expression of both protein and mRNA of Pim-1 in a dose-dependent manner. |
| In Vivo | Inecalcitol (1.3 mg/kg; i.p.; 3 times per week; for 42 days) inhibits androgen-responsive prostate cancer growth in vivo[1]. Pharmacokinetic studies show that plasma half-life of Inecalcitol (C57Bl/6J mice; 1.3 mg/kg; i.p.) is 18.3 minutes in mice[1]. Animal Model: Male BNX nu/nu mice (8 weeks of age) injected with LNCaP cells[1] Dosage: 1.3 mg/kg Administration: i.p.; 3 times per week; for 42 days Result: Inhibited androgen-responsive prostate cancer growth in vivo. |
