Novel C-9, 9'-O-acyl esters of (-)-carinol as free-radical scavengers and xanthine oxidase enzyme inhibitors: synthesis and biological evaluation

Med Chem. 2013 Feb;9(1):100-3. doi: 10.2174/157340613804488288.

Abstract

New compounds with hydrophyllic esters of (-)-carinol were synthesized and evaluated as xanthine oxidase enzyme inhibitors and antioxidants. Aliphatic esterfication of C-9,9'-OH groups of (-)-carinol resulted in lowering antioxidant and xanthine oxidase inhibitory activities. However certain aromatic acyl esters considerably improved the xathine oxidase inhibition. Aromatic esterification with electron withdrawing substitutions would preferred for improvement in XOD inhibition while retaining radical scavenging activity, electron withdrawing substitution led to the loss of free radical scavenging property and neutral substituents decrease the enzyme inhibitory potential.
