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].

IC50 & Target

IC50: 22 nM (HNE)[1] Ki: 0.31 nM (HNE)[1]

In Vitro

GW-311616 (150 μM; 48 hours) markedly suppresses NE activity in U937 and K562 cells lines[2].
GW311616A (20-320 μM; 48 hours; U937 cells) treatment inhibits proliferation and induces apoptosis in leukemia cells[2].
GW-311616 (150 μM; U937 cells) treatment can increase the protein expression levels of Bax and decrease the expression of Bcl-2[2].

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 (t1/2) 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 is achieved 6 hours after dosing, with activity returning towards control values. Single oral dose of 2 mg/kg rapidly abolishes circulating enzyme activity, and greater than 90% inhibition is maintained for 4 days.
