Freselestat quarterhydrate (ONO-6818 quarterhydrate) 是一种有效且具有口服活性的嗜中性粒细胞弹性蛋白酶 (neutrophil elastase) 抑制剂，Ki 为 12.2 nM。Freselestat quarterhydrate 对其他蛋白酶（例如胰蛋白酶，蛋白酶3，胰弹性蛋白酶，纤溶酶，凝血酶，胶原酶，组织蛋白酶G和鼠巨噬细胞弹性蛋白酶）的活性低 100 倍以上，并具有有效的抗炎活性。
| 生物活性 |
Freselestat quarterhydrate (ONO-6818 quarterhydrate) is a potent and orally active neutrophil elastase inhibitor with a Ki of 12.2 nM. Freselestat quarterhydrate is >100-fold less-active against other proteases such as trypsin, protein-ase 3, pancreatic elastase, plasmin, thrombin, collagenase, cathepsin G, and murine macrophage elastase. Freselestat quarterhydrate has a potent anti-inflammatory activity. |

| 体外研究 |
Simulated extracorporeal circulation is established by recirculating fresh heparinized (3.75 U/mL) human blood for 120 minutes in a membrane oxygenator and a roller pump with and without 1.0 μM of Freselestat (ONO-6818). Neutrophil elastase levels are significantly lower in the Freselestat group. Freselestat significantly reduces interleukin 8 and C5b-9 production. Freselestat does not modulate changes of CD11b and L-selectin during recirculation. |

| 体内研究 |
Freselestat (ONO-6818; 10-100 mg/kg; oral administration; daily; for 8 weeks) treatment attenuates dose-dependently HNE-induced increases in lung myeloperoxidase activity, hemoglobin, and neutrophil count in bronchoalveolar lavage fluid. ONO-6818 inhibits acute lung injury induced by HNE by minimizing lung hemorrhage and accumulation of neutrophils in the lung.
