生物活性
Fumitremorgin C (FTC) is a fungal toxin of the diketopiperazines family of compounds. In mammalian cells, FTC is tremorgenic and causes cell cycle arrest. Fumitremorgin C has been shown to reverse resistance to doxorubicin, mitoxantrane, and topotecan in non-Pgp (P-glycoprotein), non-MRP (multidrug resistance protein) multidrug-resistance (MDR) cells. This reversal of resistance is associated with an increase in drug accumulation. Fumitremorgin C is a specific, selective, and potent inhibitor at micromolar concentrations of the breast cancer resistant protein (BCRP/ABCG2), an ABC transporter associated with chemotherapy resistance. FTC, in combination with mitoxantrone, can be used for the detection of ABCG2 functional activity in several cell lines.

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。
