生物活性
Nicaraven is a novel free radical scavenger. Nicaraven inhibits human platelet aggregation in vitro. The maximum aggregation rate induced by adenosine diphosphate (ADP) was significantly inhibited by nicaraven at concentration ranges of 3.50 x 10(-4) mol/L or higher in the healthy volunteer platelets. The maximum aggregation rate induced by collagen was significantly inhibited by 1.75 x 10(-3) mol/L of nicaraven. Using platelets from patients with cerebral thrombosis, the maximum aggregation rate induced by ADP was significantly inhibited by 1.75 x 10(-3) mol/L of nicaraven. Furthermore, the maximum aggregation rate induced by collagen were significantly reduced by 1.75 x 10(-3) mol/L of nicaraven. Nicaraven induces dose-dependent inhibition of platelet aggregation in both healthy volunteers and patients with cerebral thrombosis.

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。
