Six analogues of 1α, 25-dihydroxy-22-oxavitamin D3 (OCT) (2), 26, 27-dimethyl OCT (5), 26, 27-diethyl OCT (6), 24-norOCT (7), 24-homoOCT (8), 24-dihomoOCT (9), and 24-trihomoOCT (10) were synthesized from the 20(S)-alcohol (11) as the common starting material. In the activity inducing differentiation of human myeloid leukemia cells (HL-60) into macrophages, 26, 27-dimethyl OCT (5) and 24-homoOCT (8) showed the highest activities. The binding properties of these analogues to the chick embryonic intestinal 1α, 25-dihydroxyvitamin D3 (1) receptor are also described.
1α, 25-二羟基-22-奥沙维他命 D3 (OCT) (2)、26, 27-二甲基 OCT (5)、26, 27-二乙基 OCT (6)、24-norOCT (7)、24-homoOCT 的六种类似物(8)、24-dihomoOCT (9) 和 24-trihomoOCT (10) 由 20(S)-醇 (11) 作为共同起始原料合成。在诱导人骨髓性白血病细胞(HL-60)向巨噬细胞分化的活性中,26, 27-二甲基OCT(5)和24-homoOCT(8)表现出最高活性。还描述了这些类似物与鸡胚肠道 1α, 25-二羟基维生素 D3 (1) 受体的结合特性。
