== Disease ==
[https://www.uniprot.org/uniprot/FA11_HUMAN FA11_HUMAN] Defects in F11 are the cause of factor XI deficiency (FA11D) [MIM:[https://omim.org/entry/612416 612416]; also known as plasma thromboplastin antecedent deficiency or Rosenthal syndrome. It is a hemorrhagic disease characterized by reduced levels and activity of factor XI resulting in moderate bleeding symptoms, usually occurring after trauma or surgery. Patients usually do not present spontaneous bleeding but women can present with menorrhagia. Hemorrhages are usually moderate.<ref>PMID:2813350</ref> <ref>PMID:1547342</ref> <ref>PMID:7888672</ref> <ref>PMID:7669672</ref> <ref>PMID:9401068</ref> <ref>PMID:9787168</ref> <ref>PMID:10027710</ref> <ref>PMID:10606881</ref> <ref>PMID:11895778</ref> <ref>PMID:15026311</ref> <ref>PMID:15180874</ref> <ref>PMID:15953011</ref> <ref>PMID:16607084</ref> <ref>PMID:18005151</ref> <ref>PMID:21668437</ref> <ref>PMID:21457405</ref> <ref>PMID:22016685</ref> <ref>PMID:22322133</ref> <ref>PMID:21999818</ref> <ref>PMID:22159456</ref> 
== Function ==
[https://www.uniprot.org/uniprot/FA11_HUMAN FA11_HUMAN] Factor XI triggers the middle phase of the intrinsic pathway of blood coagulation by activating factor IX.

== Publication Abstract from PubMed ==
Factor XIa inhibitors are promising novel anticoagulants which show excellent efficacy in preclinical thrombosis models with minimal effects on hemostasis. The discovery of potent and selective FXIa inhibitors which are also orally bioavailable has been a challenge. Here, we describe optimization of the imidazole-based macrocyclic series and our initial progress towards meeting this challenge. A two-pronged strategy, which focused on replacement of the imidazole scaffold and the design of new P1 groups, led to the discovery of potent, orally bioavailable pyridine-based macrocyclic FXIa inhibitors. Moreover, pyridine-based macrocycle 19, possessing the phenylimidazole carboxamide P1, exhibited excellent selectivity against relevant blood coagulation enzymes and displayed antithrombotic efficacy in a rabbit thrombosis model.
