Stereoselective synthesis and biological evaluation of 3,4-diaminocyclohexanecarboxylic acid derivatives as factor Xa inhibitors

Add time:09/07/2019    Source:sciencedirect.com

There have been few reports on synthetic methods for cis-1,2-diaminocyclohexane bearing a third ring substituent. Starting from 3-cyclohexenecarboxylic acid, we developed efficient methods for synthesizing the 3,4-diaminocyclohexanecarboxylic acid derivatives 2–5. We also evaluated their anti-Xa and anticoagulant activities. Among the compounds, acid 2a and amide 2b exhibited the most potent in vitro anti-fXa activity, indicating that the position and stereochemistry of a polar functional group on the cyclohexane ring greatly affected the in vitro anti-fXa activity.
