[https://www.uniprot.org/uniprot/FA10_HUMAN FA10_HUMAN] Defects in F10 are the cause of factor X deficiency (FA10D) [MIM:[https://omim.org/entry/227600 227600]. A hemorrhagic disease with variable presentation. Affected individuals can manifest prolonged nasal and mucosal hemorrhage, menorrhagia, hematuria, and occasionally hemarthrosis. Some patients do not have clinical bleeding diathesis.<ref>PMID:2790181</ref> <ref>PMID:1973167</ref> <ref>PMID:1985698</ref> <ref>PMID:7669671</ref> <ref>PMID:8529633</ref> <ref>PMID:7860069</ref> <ref>PMID:8845463</ref> <ref>PMID:8910490</ref> <ref>PMID:10468877</ref> <ref>PMID:10746568</ref> <ref>PMID:10739379</ref> <ref>PMID:11248282</ref> <ref>PMID:11728527</ref> <ref>PMID:12945883</ref> <ref>PMID:15650540</ref> <ref>PMID:17393015</ref> <ref>PMID:19135706</ref>

== Publication Abstract from PubMed ==
Modification of a series of pyrazole factor Xa inhibitors to incorporate an aminobenzisoxazole as the P(1) ligand resulted in compounds with improved selectivity for factor Xa relative to trypsin and plasma kallikrein. Further optimization of the P(4) moiety led to compounds with enhanced permeability and reduced protein binding. The SAR and pharmacokinetic profile of this series of compounds is described herein. These efforts culminated in 1-(3'-aminobenzisoxazol-5'-yl)-3-trifluoromethyl-N-[2-fluoro-4-[(2'-dimeth ylaminomethyl)imidazol-1-yl]phenyl]-1H-pyrazole-5-carboxyamide (11d), a potent, selective, and orally bioavailable inhibitor of factor Xa. On the basis of its excellent in vitro potency and selectivity profile, high free fraction in human plasma, good oral bioavailability, and in vivo efficacy in antithrombotic models, the HCl salt of this compound was selected for clinical development as razaxaban (DPC 906, BMS-561389).
