coagulation factor X/Coagulation factor X in Human (target type: SINGLE PROTEIN) [ChEMBL: CHEMBL244] [GtoPdb: 2359] [UniProtKB: P00742]
ChEMBL	Inhibition of factor 10a by dixon plot method	B	6.69	pKi	206	nM	Ki	J Med Chem (2012) 55: 1171-1180 [PMID:22276953]
ChEMBL	Enzyme Assay: The inhibition constants for human plasmin (h plasmin), human plasma kallikrein (h PK), thrombin and factor Xa were determined in analogy to a previously disclosed method (Stürzebecher et al., J. Med. Chem., 40, 3091-3099 (1997)), using a microplate reader (Multiscan Ascent, Thermo Scientific) at 405 nm. The reactions to determine the inhibition of human plasmin and human plasma kallikrein were carried out at 25° C. in 200 μl 50 mM Tris×HCl buffer pH 8.0 (containing 0.154 M NaCl, 2% ethanol and inhibitor in appropriate concentrations) and 25 μl substrate solution. Reactions were started by addition of 50 μl of enzyme solution.	B	6.69	pKi	206	nM	Ki	US-8921319-B2. Serine protease inhibitors (2014)
