Hazard Information

Uses

GW-311616 is a potent, orally bioavailable, long duration and selective human neutrophil elastase (HNE) inhibitor with IC50 value of 22 nM and Ki value of 0.31 nM[1].

Biological Activity

Potent and selective inhibitor of human leukocyte elastase (HLE) (IC 50 = 22 nM); displays > 4500-fold selectivity over other human serine proteases. Orally active in vivo .

in vivo

GW-311616 (2 mg/kg; oral administration) rapidly abolishes the circulation of neutrophil elastase (NE) in dogs, while >90% inhibition is maintained for 4 days. This prolonged effect is independent to be due to penetration of neutrophils in bone marrow by orally administrated GW-311616. GW-311616 has moderate terminal elimination half-life (t_1/2) of 1.1 hours and 1.5 hours for dog (2 mg/kg, oral), rat (2 mg/kg, oral), respectively^[3].

Animal Model:	Dogs (9-month-old)^[3]
Dosage:	0.22 mg/kg, 0.66 mg/kg and 2 mg/kg (Pharmacokinetic study)
Administration:	Oral administration
Result:	At 0.22 mg/kg, greater than 50% inhibition of elastase was achieved 6 hours after dosing, with activity returning towards control values. Single oral dose of 2 mg/kg rapidly abolished circulating enzyme activity, and greater than 90% inhibition was maintained for 4 days.

storage

Store at -20°C
