Calcipotriol is an analogue of vitamin D3. [1]

Calcipotriol is a ligand of VDR-like receptors and is used as a first-line topical agent in the treatment of psoriasis.[1-2] Calcipotriol is much less effective in causing hypercalcemia.[3] The vitamin D receptor is found on the cells of many different tissues including T cells of the immune system. T cells are known to play a role in psoriasis, and the binding of calcipotriol to VDR modulates the T cells gene transcription of cell differentiation and proliferation related genes. Calcipotriol induced apoptosis in eratinocytes isolated from psoriatic plaques at 100 nM for 20 h.[4] Calcipotriol also induced autophagy in both HeLa cells and keratinocytes.[2] Calcipotriol inhibited the proliferation of HL-60 and MCF-7 cells dose-dependently from 1 nM-1000 nM.[5] Calcipotriol is a potent inducer of terminal differentiation in cultured human keratinocytes.[3] Calcipotriol also decreased the mRNA expression/production of human cathelicidin antimicrobial protein (hCAP18) and LL37 peptide by IL-17A/IL-22-stimulated keratinocytes at 40 nM.[6]

Shipping ConditionEvaluation sample solution: ship with blue ice. All other available sizes: ship with RT, or blue ice upon request.
General tipsFor obtaining a higher solubility, please warm the tube at 37°C and shake it in the ultrasonic bath for a while. Stock solution can be stored below -20°C for several months.


Cell experiment [1]:

Cell lines

Human HL-60 and MCF-7 cell lines

Preparation method

Soluble in DMSO > 16.7mg/mL. General tips for obtaining a higher concentration: Please warm the tube at 37℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20℃ for several months.

Reacting condition

1, 10, 100, 1000 nM for 24 h


Calcipotriol revealed a strong proliferation inhibition in HL-60 cells, the potentiation of the antiproliferative effect of CIS(cisplatin) could be observed. In MCF-7 cells, a lower dose of TX (tamoxifen) in combination with calcipotriol caused an increase in the G0/G1 and a decrease in the G2/M stage as compared to TX alone.

Clinical experiment [2]:

Diseases models

Patients with vulgaris psoriasis aged ≥18 years

Dosage form

Foam of calcipotriol 50μg/g plus betamethasone 0.5 mg/g, 4, 8, 12 weeks, topical treatment


A greater proportion of patients achieved modified Psoriasis Area and Severity Index 75 and 90 at weeks 4, 8, and 12 with the calcipotriol 50μg/g plus betamethasone 0.5 mg/g (Cal/BD) foam.

Other notes

Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.
