[[http://www.uniprot.org/uniprot/FA11_HUMAN FA11_HUMAN]] Defects in F11 are the cause of factor XI deficiency (FA11D) [MIM:[http://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> | |||

== Publication Abstract from PubMed == | |||
Novel inhibitors of FXIa containing an (S)-2-phenyl-1-(4-phenyl-1H-imidazol-2-yl)ethanamine core have been optimized to provide compound 16b, a potent, reversible inhibitor of FXIa (Ki = 0.3 nM) having in vivo antithrombotic efficacy in the rabbit AV-shunt thrombosis model (ID50 = 0.6 mg/kg + 1 mg kg-1 h-1). Initial analog selection was informed by molecular modeling using compounds 11a and 11h overlaid onto the X-ray crystal structure of tetrahydroquinoline 3 complexed to FXIa. Further optimization was achieved by specific modifications derived from careful analysis of the X-ray crystal structure of the FXIa/11h complex. Compound 16b was well tolerated and enabled extensive pharmacologic evaluation of the FXIa mechanism up to the ID90 for thrombus inhibition. | |||
