生物活性
Pyocyanin, a blue-green pigment belonging to phenazine pigments, is a redox-active phenazine. Pyocyanin is an electron receptor, which stimulates redox cycling in bacteria, liver cells, and human epithlial cell lines. Pyocyanin enhances the oxidative metabolism, which in turn increases the formation of intracellular reactive oxygen species (ROS) via reduction of NADPH.Pyocyanin also increases the release of IL-8 by airway epithelial cells bothin vitroandin vivo. This involves signal transduction pathways that include oxidants, protein tyrosine kinases, and MAP kinases. IL-8 secretion by these cells is in synergy with inflammatory cytokines.Pyocyanin has been shown to accelerate neutrophil apoptosisin vitro, resulting in resolution of acute inflammation, which is beneficial for bacteria survival.

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。
