    Tachysterol 3

    		VD/VDR Endogenous Metabolite Metabolic Disease Inflammation/Immunology
    Tachysterol 3 is a photoproduct of Previtamin D3 (HY-130705). Previtamin D3 is an orally active, thermolabile steroidal compound that generates vitamin D3, as well as biologically inactive lumisterol and tachysterol. Previtamin D3 is synthesized in the skin of humans and rats via the UV-B-mediated photoconversion of 7-dehydrocholesterol. Previtamin D3 lacks direct anti-rachitic activity, and its in vivo activity relies on the vitamin D3 it produces. Previtamin D3 can be used in studies related to rickets and vitamin D metabolism .

    Pre-vitamin D3 decanoate

    		VD/VDR Others
    Pre-vitamin D3 decanoate is a derivative of vitamin D3 that can be converted into the active form of vitamin D in the body. Pre-vitamin D3 decanoate is first converted to 25-hydroxyvitamin D3 in the liver and then further converted to 1,25-dihydroxyvitamin D3 in the kidneys. During preparation, vitamin D3 may react with the triglycerides in the formulation to form ester compounds, and this esterification affects the stability and bioavailability of vitamin D3. Pre-vitamin D3 decanoate can be used in the study of certain diseases associated with vitamin D, such as osteoporosis, autoimmune diseases, and certain cancers .

    Previtamin D2

    		Endogenous Metabolite Others
    Previtamin D2 is a precursor to Vitamin D2 (ergocalciferol) , formed through the photoisomerization of ergosterol, a compound found in fungi and some plants. Exposure to ultraviolet (UV) light triggers the conversion of ergosterol to previtamin D2, which then rapidly isomerizes to vitamin D2.
