New 1α,25-dihydroxy vitamin D3 analogues with side chains attached to C-18: Synthesis and biological activity

A new class of analogues of 1α,25-dihydroxy vitamin D3 has been synthesised, in which the side chain (C-23 to C-27) has been removed and where new hydroxylated side chains have been attached to the C-18 methyl group. These analogues show antipr
