'''Factor Xa in complex with the inhibitor 4-[(5-chloroindol-2-yl)sulfonyl]-2-(2-methylpropyl)-1-[[5-(pyridin-4-yl) pyrimidin-2-yl]carbonyl]piperazine'''
===Factor Xa in complex with the inhibitor 4-[(5-chloroindol-2-yl)sulfonyl]-2-(2-methylpropyl)-1-[[5-(pyridin-4-yl) pyrimidin-2-yl]carbonyl]piperazine===




==Overview==
<!--  
Compound 7 was identified as the active metabolite of 6 by HPLC and mass spectral analysis. Modification of lead compound 7 by transformation of its N-oxide 6-6 biaryl ring system and fused aromatics produced a series of non-basic fXa inhibitors with excellent potency in anti-fXa and anticoagulant assays. The optimized compounds 73b and 75b showed sub to one digit micromolar anticoagulant activity (PTCT2). Particularly, anti-fXa activity was detected in plasma of rats orally administered with 1mg/kg of compound 75b.
The line below this paragraph, {{ABSTRACT_PUBMED_15911309}}, adds the Publication Abstract to the page
(as it appears on PubMed at http://www.pubmed.gov), where 15911309 is the PubMed ID number.
