2,3,5‐Trimethyl‐6‐(12‐hydroxy‐5, 10‐dodecadiynyl)‐1.4‐benzoquinone (AA861) strongly inhibited epidermal lipoxygenase activity which was determined by the formation of [14 C]12‐hydroxy‐5,8,10,14‐eicosatetraenoic acid by incubating [l4 C]arachidonic acid with cytosol fraction of epidermal homogenate of ***CD‐1 mice. AA861 failed to inhibit epidermal cyclooxygenase activity. The present results indicate that AA861 is a potent inhibitor of 12‐lipoxygenase in mouse epidermis (IC50 1.9 μM). 1985 Royal Pharmaceutical Society of Great Britain
