== Disease ==
[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> 
== Function ==
[https://www.uniprot.org/uniprot/FA10_HUMAN FA10_HUMAN] Factor Xa is a vitamin K-dependent glycoprotein that converts prothrombin to thrombin in the presence of factor Va, calcium and phospholipid during blood clotting.

== Publication Abstract from PubMed ==
A series of cis-1,2-diaminocyclohexane derivatives possessing a 6-6 fused ring for the S1 moiety were synthesized as novel factor Xa (fXa) inhibitors. The synthesis, structure-activity relationship (SAR), and physicochemical properties are reported herein, together with the discovery of compound 45c, which has potent anti-fXa activity, good physicochemical properties and pharmacokinetic (PK) profiles, including a reduced negative food effect.

Design, synthesis, and SAR of cis-1,2-diaminocyclohexane derivatives as potent factor Xa inhibitors.
