2-Arylalkyl-substituted anthracenones as inhibitors of 12-lipoxygenase enzymes. 1. Structure–activity relationships of the terminal aryl ring
摘要:
A series of 2-arylmethyl-substituted anthracenones were synthesized and tested as inhibitors of three types of 12-lipoxygenase isoforms in epidermal homogenate of mice, bovine platelets and porcine leucocytes. Their inhibitory activities were compared with those to inhibit the 5-lipoxygenase enzyme in bovine leucocytes. Structure-activity relationships are described with particular emphasis on modifications of the terminal aryl nucleuS. The ability of the compounds to selectively inhibit the 12-lipoxygenase enzymes was dependent on a high overall lipophilicity of the inhibitor, whereas compounds with decreased lipophilicity were also inhibitors of the 5-LO enzyme. Among the more lipophilic inhibitors, the unsubstituted 2-phenylmethyl analogue 6a as well as the carboxylic acid ester 6q ap eared to be selective inhibitors of platelet-type 12-LO isoform.
