Title: Cyclic ether vitamin D3 compounds, 1.alpha.(OH)3-EPI-vitamin D3 compounds and uses thereof
Abstract:Novel cyclic ether vitamin D3 compounds having a cyclic ether side chain are disclosed. These compounds were first identified as metabolites of 3-epi vitamin D3 produced via a tissue-specific metabolic pathway which catalyzes the formation of a cyclic ether structure. Also disclosed are 1.alpha.(OH) 3-epi vitamin D3 compounds, which are produced via the epimerization of a 3-.beta.-hydroxyl group of 1.alpha.(OH) vitamin D3 precursor in vivo. The vitamin D3 compounds of the present invention can be used as substitutes for natural and synthetic vitamin D3 compounds.
