生物活性

Calcipotriol是1,25-Dihydroxyvitamin D3类似物，可作用于银屑病。Calcipotriol increased hCAP18 mRNA expression in IL-17/IL-22-stimulated keratinocytes. However, LL37 peptide in the culture supernatants was reduced by calcipotriol. Calcipotriol and FTY720 augment IL-2-activated NK cell lysis of K562 and RAJI tumor cell lines as well as immature (i) and mature (m) DCs, with variable efficacies. Vitamin D3, calcipotriol and FTY720 enhance NK17/NK1 cell lysis of K562 cells, suggesting that a possible mechanism of action for these drugs is via activating these newly described cells. MC903 (calcipotriol) is a novel vitamin D3 analogue which is at least 100 times less potent than 1,25-(OH)-2-D3 in its effects on calcium homeostasis.

化学数据

不同实验动物依据体表面积的等效剂量转换表（数据来源于FDA指南）

例如，依据体表面积折算法，将化合物用于小鼠的剂量20 mg/kg 换算成大鼠的剂量，需要将20 mg/kg 乘以小鼠的K_m系数（3），再除以大鼠的K_m系数（6），得到化合物用于大鼠的等效剂量为10 mg/kg。
