The diene system of 1α,25-dihydroxy-19-norvitamin D3 was replaced by a stable amide bond. A 3-hydroxypropoxy group, which was effective on enhancing binding affinity of 1α,25-dihydroxyvitamin D3 for vitamin D receptor (VDR), was introduced to the C2-position of the amide type analogue of 1α,25-dihydroxy-19-norvitamin D3. The amide analogue was found to be not suitable for binding to the ligand binding domain of the bovine thymus VDR, and additional modification at the C2-position did not improve the affinity. Potency in induction of HL-60 cell differentiation was evaluated for the novel amide analogues (3a-c).
