GW311616 is a potent, intracellular, orally bioavailable, long duration inhibitor of human neutrophil elastase(HNE) with IC50 of 22 nM. GW311616 is the free base form of GW311616A. The HNE inhibitor GW311616A is selective over other human serine proteases (IC50 values >100 uM for trypsin, cathepsin G, and plasmin, >3 mM for chymotrypsin and tissue plasminogen activator). Acetylcholinesterase is not inhibited by GW311616A at 100 uM.

Animal A (mg/kg) = Animal B (mg/kg) multiplied by | Animal B Km |
Animal A Km |
For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.
