Practical synthesis and evaluation of the biological activities of 1α,25-dihydroxyvitamin D3 antagonists, 1α,25- dihydroxyvitamin D3-26,23-lactams. Designed on the basis of the helix 12-folding inhibition hypothesis

A practical synthetic route to novel vitamin D antagonists of DLAM (1α,25-dihydroxyvitamin D3-26,23-lactam) was developed from vitamin D2 via the 1,3-dipolar cycloaddition reaction as a key step. Six DLAM derivatives (24 compounds) w
