生物活性
Fuzuopali is a poly (ADP-ribose) polymerase inhibitor (PARP) inhibitor with IC50 of 1.46±0.72 nM for a cell‐free enzymatic assay, with superior antitumor activity. Fluzoparib selectively inhibits the proliferation of homologous recombination repair (HR)‐deficient cells, and sensitizes both HR‐deficient and HR‐proficient cells to cytotoxic agents. Fluzoparib acts synergistically to inhibit cell growth and promote apoptosis among lung cancer cells.
In vivo, Fluzoparib (30 mg/kg; oral gavage; 21 days) apparently inhibits the growth of tumor with an inhibition rate of 59% (day 21) at 30 mg/kg, and it does not cause significant loss of body weight in Nude mice bearing MDA‐MB‐436 (BRCA1‐deficient) model.

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。
