Abstract/OtherAbstract:
Ester analogs of the antipsoriatic drug acitretin were synthesized by coupling either anilines with N-protected indole-3-carboxylic acid, followed by deprotection and coupling with O-monoprotected dicarboxylic acids or Wittig reaction of indole-3-carboxaldehyde, 3-acetyl-1-tosylpyrrole and 4-amino-9-fluorenone with Ph3P=CHCO2tBu, followed by N-deprotection, where necessary, and finally coupling with cinnamoyl fluorides. Corresponding free acids were obtained through TFA-mediated carboxyl group deprotection. Although these analogs and acitretin showed very low reducing abilities, analogs 5, 6, 8 and 12 strongly inhibited LOX with IC50 values ranging from 35-65 microM. Acitretin and its analogs 5-7, 10, 11 and 15 inhibited lipid peroxidation more strongly than trolox whereas acitretin and analog 4 were in vivo more potent anti-inflammatory agents on rat paw oedema induced by Carrageenan than indomethacin.
