产品介绍
Freselestatquarterhydrate(ONO-6818quarterhydrate)是一种有效且具有口服活性的嗜中性粒细胞弹性蛋白酶(neutrophilelastase)抑制剂,Ki为12.2nM。Freselestatquarterhydrate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。

产品描述

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[1][2][3][4].

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[3].

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[1].
