Description

General description

Active hormonal form of vitamin D, formed by the renal 1-hydroxylation of 25-(OH)D₃. Has immunomodulatory properties in vitro and in vivo. Prevents the development of clinical diabetes in NOD mice, which are an animal model of human autoimmune diabetes. Induces reversible hydrolysis of the sphingomyelin cycle and generates ceramide. Stimulates intestinal Ca²⁺ and phosphate transport and mobilizes Ca²⁺ from bone. Involved in cellular differentiation, carcinogenesis, and insulin secretion.

Application

• Evaluation system for cell-permeable CYP3A4 inhibitory activity using 1α,25-dihydroxy-vitamin D(3)-induced intestinal cell lines.: Ueno et al. developed an evaluation system for cell-permeable CYP3A4 inhibitory activity utilizing 1α,25-dihydroxy-vitamin D3-induced intestinal cell lines. This system helps in screening for CYP3A4 inhibitors, which are critical in drug metabolism and interaction studies (Ueno et al., 2021).
