Mifepristone (1) was found to be stable against ultraviolet light under the usual storage conditions. Upon irradiation for two weeks it gave two photoproducts, characterized as (11β, 17β)‐17‐Hydroxy‐11‐[4‐(methylamino)‐phenyl]‐17‐(1‐propinyl)‐19‐norandrosta‐4,9‐dien‐3‐one (2) and [5R,7E, 8R,8aR]‐5‐[4‐(dimethylamino)phenyl]‐4,5,6,7,8,8a,9,10‐octahydro‐7‐methyl‐8‐(3‐oxo‐4‐hexinyl)‐2(3H)‐phenanthrenone
发现米非司酮 (1) 在通常的储存条件下对紫外线是稳定的。照射两周后,它产生两种光产物,特征为 (11β, 17β) -17 - 羟基 - 11- [4- (甲基氨基) -苯基] -17- (1 - 丙炔基) -19 - 诺兰德罗斯塔 - 4,9-二烯 - 3 - 一 (2) 和 [5R, 7E, 8R, 8aR] -5- [4- (二甲氨基) 苯基] -4,5,6,7,8,8a, 9,10 - 八氢 - 7-甲基-8-(3-氧代-4-己炔基)-2(3H)-菲酮(3)。基于X射线衍射1的晶体结构,2和3的形成可以用晶体中的分子堆积来解释。
