1α,25-Dihydroxyvitamin D3-3β-bromoacetate, a potential cancer therapeutic agent: synthesis and molecular mechanism of action

Synthesis of 1α,25-dihydroxyvitamin D(3)-3β-bromoacetate (1,25(OH)(2)D(3)-3-BE), a potential anti-cancer agent is presented. We also report that mechanism of action of 1,25(OH)(2)D(3)-3-BE may involve reduction of its catabolism, as evidenced by the reduced and delayed expression of 1α,25-dihydroxyvitamin D(3)-24-hydroxylase (CYP24) gene in cellular assays.
