ZD-0892是选择性和有效的中性粒细胞弹性蛋白酶(neutrophilelastase)抑制剂，对于人嗜中性粒细胞弹性蛋白酶和猪胰弹性蛋白酶的Ki值分别为6.7和200nM。
ZD-0892 is a selective and potent inhibitor of a neutrophil elastase with Kis of 6.7 and 200 nM for human neutrophil elastase and porcine pancreatic elastase, respectively.
ZD0892 administration to DBA/2 mice infected with the EMC virus results in reduced myocardial elastolytic activity and coronary microvascular perfusion injury. ZD0892 decreases the pathologic severity of the myocardial lesions associated with murine viral myocarditis[1]. ZD-0892 can reverse advanced pulmonary vascular disease produced in rats[2].

Animal experiment: | Rats[2]Adult male Sprague-Dawley rats (250-300 g in body weight) are induced pulmonary hypertension. In addition to a group of untreated rats, the experimental groups include rats that receive twice-daily gavage tube feedings of ZD0892, at a dose of 240 mg/kg per day or vehicle (5% polyethylene glycol or dimethyl sulfoxide). Rats are examined after 7 days of treatment.Mice[1]DBA/2 male mice 8 weeks old is used. ZD0892 is given in a dose of 60 mg/kg or 120 mg/kg[1]. |
