naturally occurring Vitamin D analogue that, in cell culture, downregulates the production of the cytokine osteopontin (OPN). OPN has been implicated in virulent asthma, and OPN knockout mice do not develop osteoporosis. As we have pursued whole animal studies with astrogorgiadiol, we have increased the scale of the synthesis. We report an improved preparation of the A-ring synthon and the scale-up of
Astrogorgiadiol 是一种天然存在的维生素 D 类似物,在细胞培养中可下调细胞因子骨桥蛋白 (OPN) 的产生。 OPN 与恶性哮喘有关,OPN 敲除小鼠不会患骨质疏松症。由于我们对 astrogorgiadiol 进行了整体动物研究,因此我们增加了合成规模。我们报告了 A 环合成子的改进制备以及非对映异构纯 D 环/侧链 chiron 的放大。
