Summary
FK706 is a potent, slow-binding and competitive inhibitor of human neutrophil elastase with an IC 50 of 83 nM and a K i of 4.2 nM. FK706 also inhibits mouse neutrophil elastase and porcine pancreatic elastase with IC 50 s of 22 nM and 100 nM, respectively, and has no inhibitory activity against other serine proteinases such as human pancreatic trypsin, human pancreatic α-chymotrypsin and human leukocyte cathepsin G. FK706 has anti-inflammatory effect [1] [2] .
IC50 & Target
In Vitro
FK706 effectively inhibits the hydrolysis of bovine neck ligament elastin (2 mg/mL final concentration) by human neutrophil elastase (4 μg/mL final concentration) with an
IC50
value of 230 nM
[1]
.
FK706 blocks the release of inflammatory chemokines, suppresses the expression of IL-8 and MCP-1 mRNA, and suppresses NF-κB activation. It seems possible that FK706 may directly blocks human lung fibroblasts activation of NF-κB, preventing expression of inflammatory chemokines during cigarette smoke–induced lung inflammation

In Vivo
FK706 (10-100 mg/kg; subcutaneous injection; for 1-6 hours; male C57BL mice) treatment significantly suppresses human neutrophil elastase (20 μg/paw)-induced paw edema in mice in a dose-dependent manner (47% inhibition at a dose of 100 mg/kg) [1] .

| Animal Model: | Male C57BL mice (6 weeks old) injected with human neutrophil elastase [1] |
| Dosage: | 10 mg/kg, 32 mg/kg, 100 mg/kg |
| Administration: | Subcutaneous injection; for 1 hour, 2 hours, 4 hours, 6 hours |
