7,7-Dimethyl-(5Z,8Z)-eicosadienoic acid

7,7-Dimethyl-(5Z,8Z)-eicosadienoic acid (DEDA), a phospholipase inhibitor, is a non-metabolizable analog of arachidonic or eicosadienoic acid. 7,7-Dimethyl-(5Z,8Z)-eicosadienoic acid (DEDA) inhibits P388D1 cell phospholipase A2 (PLA2) (IC50 = 16 uM) and snake venom PLA2 (IC50 = 14 uM).
