Secalciferol  (Synonyms: (24R)-24,25-Dihydroxyvitamin D3)

Cat. No.: HY-32343 Purity: 99.89%
SDS COA Handling Instructions

Secalciferol ((24R)-24,25-Dihydroxyvitamin D3) is the major active metabolite of Vitamin D. Secalciferol activates vitamin D receptor (VDR) with an EC50 value of 150 nM. Secalciferol is involved in a wide range of biological functions such as calcium homeostasis, cellular differentiation and proliferation processes, as well as other functions related to the immune system, which is promising for research of rickets, osteomalacia, hypercalcemia and autoimmune disorders.

Description

Secalciferol ((24R)-24,25-Dihydroxyvitamin D3) is the major active metabolite of Vitamin D. Secalciferol activates vitamin D receptor (VDR) with an EC50 value of 150 nM. Secalciferol is involved in a wide range of biological functions such as calcium homeostasis, cellular differentiation and proliferation processes, as well as other functions related to the immune system, which is promising for research of rickets, osteomalacia, hypercalcemia and autoimmune disorders[1][2][3][4][5].

IC50 & Target

Human Endogenous Metabolite

 

In Vitro

Secalciferol of a part of the glucuronides is deconjugated by the enzyme from bacteria in the intestine and is probably reabsorbed and further oxidized to other metabolites in rat intestine[2].
Secalciferol is metabolized by β-glucuronidase to 24,25(OH)2D3-3G and -24G in rat bile[2].
Secalciferol (100 pM-10 μM, 24 h) dose-dependently activates vitamin D receptor (VDR) with an EC50 value of 150 nM, similar to that by Calcitriol (HY-10002) in the IZ-CYP24 and 12-VDRE cells[3].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

Secalciferol (1-1000 μg/kg, i.p., daily for 28 days) dose dependently increases the length of the fifth lumbar spine in the hypophosphatemic (Hyp) mice[1].
Secalciferol (1 mg/kg, s.c., daily for 28 days) improves the rachitic bone and increases mineralized bone volume in the Hyp mice[1].
Secalciferol (0 or 5 ppm, powder fiet for 57 weeks) induces hyperplasia and neoplasia of the adrenal medulla with increase in cell prpliferative activity in rats[4].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
