26, 27-Diethyl-1α, 25-dihydroxyvitamin D3 (7) and 24, 24-difluoro-24-homo-1α, 25-dihydroxyvitamin D3 (8) were synthesized. They had almost no vitamin D activity but were more active than 1α, 25-dihydroxyvitamin D3 (1) in tests for induction of cell differentiation.
合成了26, 27-
二乙基-1α, 25-二羟基
维生素D3 (7) 和24, 24-二
氟-24-同源-1α, 25-二羟基
维生素D3 (8)。它们几乎没有
维生素D活性,但在诱导细胞分化的测试中比1α, 25-二羟基
维生素D3 (1) 更活跃。
