Calcipotriol hydrate (Daivonex; Dovonex; MC-903; PRI-2201; Psorcutan; Sorilux), the hydrated form of calcipotriol, is a synthetic calcitriol/Vitamin D3 (VD3) analog and a potent agonist of the VD3 receptor (VDR) used in the treatment of psoriasis and marketed under the trade name Dovonex.

Maxacalcitol-D6 is the hexa-deuterated form (at the 26,27-dimethyl group) of Maxacalcitol which is a novel calcitriol analog without hypercalcemic side effects. Maxacalcitol (22-Oxacalcitriol) acts as a VDR agonist. Reference: Res.Vet.Sci. (2000)68 79.

Calcifediol (also known as 25-hydroxyvitamin D3; 25-hydroxy VD3) is the major circulating metabolite of vitamin D3 in the blood and is the form that is tested in medicine to determine vitamin D deficiency, namely, the test of 25-hydroxy vitamin D (calcifediol) levels to evaluate how much vitamin D is in the body.

Vitamin D4 is an analog of Vitamin D with potential biological activities.

Calcitriol (RO215535, Topitriol; 1,25(OH)2D3) is the metabolically/hormonally active form of vitamin D and a vitamin D receptor (VDR) agonist.

Dihydrotachysterol is a novel, synthetic vitamin D analogue that is activated in the liver and does not require renal hydroxylation like vitamin D2 (ergocalciferol) and vitamin D3 (cholecalciferol).

Elocalcitol (BXL-628; BXL628; BXL 628) is a novel calcitriol and vitamin D3 analogue that can activate vitamin D receptor (VDR).

Eldecalcitol is a drug used in Japan for the treatment of osteoporosis. It is an analogue of vitamin D.
