Oxygenated derivates of arachidonic acid and eicosapentaenoic acid which contain conjugated tetraene structures and are non-cyclized C20 carboxylic acids were first isolated and characterized from human and porcine leukocytes (Serhan, C.N. et al, 1984, Biochem. Biophys. Res. Commun. 118, 943-949; Wong, P.Y.-K., et al, 1985, Biochem. Biophys. Res. Commun. 126, 765-775). The trivial names lipoxins and lipoxenes have been introduced for compounds belonging to each of these series. Here, we propose that tetraene-containing compounds derived from arachidonic acid be denoted as lipoxins (LX) of the four series (i.e. lipoxin A4 or LXA4 and lipoxin B4 or LXB4) and those derived from eicosapentaenoic be termed lipoxins of the five series (i.e. lipoxin A5 or LXA5 and lipoxin B5 or LXB5).
