Design and synthesis of 4-methoxyphenylacetic acid esters as 15-lipoxygenase inhibitors and SAR comparative studies of them
摘要:
A group of 4-methoxyphenylacetic acid esters were designed, synthesized and evaluated as potential inhibitors of soybean 15-lipoxygenase (SLO) on the basis of eugenol and esteragol structures. Compounds 7d-e showed the best IC50 in SLO inhibition (IC50 = 3.8 and 1.9 mu M, respectively). All compounds were docked in SLO active site and showed that carbonyl group of compounds is oriented toward the Fe-III-OH moiety in the active site of enzyme and fixed by hydrogen bonding with hydroxyl group. It is assumed that lipophilic interaction of ligand-enzyme would be in charge of inhibiting the enzyme activity. The selectivity of the synthetic esters in inhibiting of 15-HLOb was also compared with 15-HLOa by molecular modeling and multiple alignment techniques. (C) 2009 Elsevier Ltd. All rights reserved.
