生物活性
Alendronate (Fosamax) is a farnesyl diphosphate synthase inhibitor with IC50 of 460 nM. It is a nitrogen-containing bisphosphate that acts as a robust inhibitor of bone resorption and induces apoptosis in osteoclasts. It causes disruption of the ruffled border and actin cytoskeleton of osteoclasts and induces in vitro apoptosis of osteoclasts and macrophages by inhibiting farnesyl diphosphate synthase (IC50 = 460 nM). It efficiently chelates metal ions and functions as a broad-spectrum MMP inhibitor (IC50 ~ 40 - 70 uM). And it also displays antimetastatic, anti-invasive and cell-adhesion-promoting properties (IC50 ~ 1 pM, in vitro invasion of prostate cancer cells).

例如,依据体表面积折算法,将化合物用于小鼠的剂量20 mg/kg 换算成大鼠的剂量,需要将20 mg/kg 乘以小鼠的Km系数(3),再除以大鼠的Km系数(6),得到化合物用于大鼠的等效剂量为10 mg/kg。
