    • Target Organs:

      RXR/RAR;COX inhibitor TargetMol T1002
    • Chemical Class:

      A monocarboxylic acid that is acetic acid in which one of the methyl hydrogens is substituted by a 1,8-diethyl-1,3,4,9-tetrahydropyrano[3,4-<ital>b</ital>]indol-1-yl moiety. A preferential inhibitor o f cyclo-oxygenase 2 and non-steroidal anti-inflammatory, it is used for the treatment of rheumatoid arthritis and osteoarthritis, and for the alleviation of postoperative pain. Administered as the rac emate, only the (<stereo>S</stereo>)-enantiomer is active. ChEBI CHEBI:4909

      Etodolac is a non-steroidal anti-inflammatory compound that is a non-selective inhibitor of COX (IC50=53.5 nM); IC50 value: 53.5 nM; Target: COX1; COX2; Post-marketing studies demonstrated that etodolac inhibition of cyclooxygenase is somewhat COX-2 selective similar to celecoxib and other COX-2 inhibitors. Unlike rofecoxib, both etodolac and celecoxib can fully inhibit COX-1 and are designated as having preferential selectivity toward COX-2. MedChem Express HY-76251
