Synthesis of 25-hydroxy-19-norvitamin D3 derivatives as prohormone type agents for anti-prostate diseases was accomplished utilizing Julia-type olefination. Synthesized compounds showed potent antiproliferative activity on an immortalized normal prostate cell line, PZ-HPV-7, which has high 1α-hydroxylase activity. Furthermore, we demonstrated that 25-hydroxy-19-norvitamin D3 was hydroxylated at the 1α position to form 1α,25-dihydroxy-19-norvitamin D3 by a recombinant human 1α-hydroxylase (CYP27B1) in a cell-free system.
