Three vitamin D3 analogues, 1 alpha,25-dihydroxy-23-oxavitamin D3 (3), 1 alpha,25-dihydroxy-23-thiavitamin D3 (4) and 1 alpha,25-dihydroxy-23-azavitamin D3 (5) were synthesized. In the differentiation-inducing activity of human myeloid leukemia cells into macrophages in vitro, the 23-aza analogue (5) showed the least activity, while no remarkable differences were observed between the 23-oxa analogue
三种维生素D3类似物分别为1种α,25-二羟基-23-草胺维生素D3(3),1种α,25-二羟基-23-硫胺素D3(4)和1种α,25-二羟基-23-氮杂维生素D3(5)。合成的。在人类髓样白血病细胞体外诱导分化为巨噬细胞的活性中,23-氮杂类似物(5)表现出最小的活性,而23-氧杂类似物(3)和23-硫杂类似物之间没有观察到显着差异。 (4),其活性低于1α,25-二羟基维生素D3(1)。
