CRYSTAL STRUCTURE OF FACTOR VII.STF COMPLEXED WITH PD0297121

Overview

The activated factor VII/tissue factor complex (FVIIa/TF) is known to play, a key role in the formation of blood clots. Inhibition of this complex may, lead to new antithrombotic drugs. A fluoropyridine-based series of, FVIIa/TF inhibitors was discovered which utilized a diisopropylamino group, for binding in the S2 and S3 binding pockets of the active site of the, enzyme complex. In this series, an enhancement in binding affinity was, observed by substitution at the 5-position of the hydroxybenzoic acid, sidechain. An X-ray crystal structure indicates that amides at this, position may increase inhibitor binding affinity through interactions with, the S1'/S2' pocket.
