  替勃龙兼具有雌激素、孕激素及雄激素活性,目前临床上主要用于自然或手术绝经后的各种症状,已上市商品替勃龙片(利维爱,Livial)可用于更年期女性的骨质疏松症。有两种晶型即晶Ⅰ型(单斜式)和晶Ⅱ型(三斜式),其中晶Ⅰ型因其更好地稳定性在制剂产品中应用较广,但两者结晶形态不是完全孤立的,在精制中,当其超过一定的过饱和状态后,晶Ⅱ会在晶Ⅰ上产生结晶,致使其结晶过程不易控制,易得混晶。

盐霉素在体外可以选择性地杀死多种肿瘤干细胞,在动物模型中对肿瘤组织具有很好的抑制作用,其抗乳腺癌肿瘤活性比紫杉醇强100倍左右,它还对其它多种恶性肿瘤以及耐药肿瘤具有很好的活性[1]。
果糖-1,6-二磷酸酶(FBPase)是肝葡萄糖异生路径的限速酶,可以催化果糖-1,6-二磷酸水解为果糖-6-磷酸[1]。已有研究表明,果糖-1,6-二磷酸酶在胰岛素抵抗和胰岛素缺乏的糖尿病动物模型的肝脏中表达增高,提示果糖-1,6-二磷酸酶对体内血糖水平具有一定的调节作用[2]。
