生物活性:
Eldecalcitol (ED-71) is an orally active vitamin D3 analogue, inhibits bone resorption and increases bone mineral density. Eldecalcitol (ED-71) displays anti-tumor effect and inhibits cell proliferation, migration and induces apoptosis by suppressing GPx-1.

体内研究:
Eldecalcitol (0.5 μg/kg;口服;每周两次,持续 4 周) 通过抑制 GPx-1 (谷胱甘肽过氧化物酶) 显示出抗癌作用。 Eldecalcitol (10,30,或 90 ng/kg;口服;每周 5 次,持续 12 周),作为一种更有效的维生素 D3 类似物,可刺激局灶性骨形成 (微型模型) 并比骨化三醇更强烈地抑制骨吸收。Animal Model:Xenograft tumor model in mice (male athymic nude BALB/c mice)
Dosage:0.5 μg/kg
Administration:Oral gavage; twice a week for 4 weeks
Result:Reduced the growth rate of tumors, and downregulated the expression levels of PCNA and MMP- 2 and upregulated the expression of Bax in the tumors.Resulted in decrease of proliferation, the inhibition of migration, and the promotion of apoptosis.
Animal Model:Ovariectomized (OVX) rat model
Dosage:10, 30, or 90 ng/kg
Administration:Oral gavage; 5-times per week for 12 weeks
Result:Increased the lumbar and femoral BMD in a dose dependent manner. Stimulated focal bone formation that started without prior bone resorption, a process known as bone minimodeling.

体外研究:
Eldecalcitol (0-50 nM;24 小时) 没有细胞毒性,可 (0.5-50 nM;24 小时) 减少 LPS (5 μg/mL) 诱导的细胞死亡。 Eldecalcitol (5 nM;24 h) 通过激活 Nrf2 及其效应分子 HO-1抑制 LPS 诱导的细胞焦亡。 Eldecalcitol (0.5-50 nM;24 h) 具有抗细胞焦亡能力,并以剂量依赖性方式降低 NLRP3、caspase-1 和 IL-1β 的表达。 Eldecalcitol (0.04-40 nM;0-48 h) 抑制SCC-15 和 CAL-27 细胞的增殖和迁移。 Eldecalcitol (0.4 nM;48 h) 使细胞周期停滞在 G0/G1 期,并通过抑制GPx-1 (谷胱甘肽过氧化物酶) 在胃癌细胞中的表达。
