GW-311616 (150 μM; 48 hours) markedly suppresses NE activity in U937 and K562 cells lines.
GW-311616 (20-320 μM; 48 hours; U937 cells) treatment inhibits proliferation and induces apoptosis in leukemia cells.
GW-311616 (150 μM; U937 cells) treatment can increase the protein expression levels of Bax and decrease the expression of Bcl-2.
Cell Viability Assay
| Cell Line: | U937 and K562 cells |
| Concentration: | 150 μM |
| Incubation Time: | 48 hours |
| Result: | Markedly suppressed NE activity. |
Apoptosis Analysis
| Cell Line: | U937 cells |
| Concentration: | 20 μM, 40 μM, 80 μM, 160 μM, 320 μM |

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.
| Animal Model: | Dogs (9-month-old) |
| 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. |
