生物活性
Podophyllotoxin (Podofilox) is a lignan (lignans) found in podophyllin resin from the roots of podophyllum plants. It is a potent spindle poison, toxic if taken internally, and has been used as a cathartic. It is very irritating to skin and mucous membranes, has keratolytic actions, has been used to treat warts and keratoses, and may have antineoplastic properties, as do some of its congeners and derivatives.

细胞系 | Human glioma cell lines CL5 |
方法 | After the Etoposide treatment, removing cells from the dish with phosphate-buffered saline (PBS) containing 0.03% trypsin and 0.27 mM ethylenediaminetetraacetic acid (EDTA) and diluting into culture dishes in appropriate numbers to yield between 20 and 200 colonies. 12 days later, fixing cultures with methanol-acetic acid, staining with crystal violet, and scoring for colonies containing more than 50 cells. The standard errors are typically less than 15% of the mean value unless otherwise stated. |

不同实验动物依据体表面积的等效剂量转换表(数据来源于FDA指南)
| 小鼠 | 大鼠 | 兔 | 豚鼠 | 仓鼠 | 狗 |
重量 (kg) | 0.02 | 0.15 | 1.8 | 0.4 | 0.08 | 10 |
体表面积 (m2) | 0.007 | 0.025 | 0.15 | 0.05 | 0.02 | 0.5 |
Km系数 | 3 | 6 | 12 | 8 | 5 | 20 |
动物 A (mg/kg) = 动物 B (mg/kg) × | 动物 B的Km系数 |
动物 A的Km系数 |
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。
