SSR 69071 Chemische Eigenschaften,Einsatz,Produktion Methoden
Beschreibung
SSR 69071 is a potent inhibitor of neutrophil elastase (K
i = 0.0168 nM for the human enzyme). It is selective for human neutrophil elastase over rat, mouse, and rabbit elastases (K
is = 3, 1.8, 58 nM, respectively). It inhibits human neutrophil elastase
ex vivo in mouse bronchoalveolar lavage (BAL) fluid (ED
50 = 10.5 mg/kg, p.o.).
In vivo, SSR 69071 (2.8 mg/kg, p.o.) reduces acute lung hemorrhage induced by human neutrophil elastase in mice. It reduces carrageenan- and human neutrophil elastase-induced paw edema in rats (ED
30s = 2.2 and 2.7 mg/kg, respectively). SSR 69071 also reduces cardiac infarct size when administered prior to ischemia or reperfusion in a rabbit model of ischemia-reperfusion injury.
Verwenden
SSR 69071 is a novel and orally active elastase inhibitor.
Biologische Aktivität
Orally active, high affinity and potent inhibitor of human leukocyte elastase (HLE) (IC 50 = 3.9 nM). Displays species-selectivity (K i values are 0.017, 1.70, 3.01, 58 and > 100 nM? for human, mouse, rat, rabbit and porcine elastase respectively). In vivo, inhibits HLE-induced lung hemorrhage in mice (ID 50 = 2.8 mg/kg) and reduces infarct size in an acute model of coronary ischemia-reperfusion injury.
