We established the stereoselective synthesis of (E)-3-methoxycarbonyl-2,4,6-trienal compound A and discovered that the compound A showed more powerful inhibitory activity toward phospholipase A2(PLA2) from bovine pancreas than manoalide which is a typical PLA2 inhibitor. As the inhibitory mechanism of PLA2 by A, the irreversible formation of dihydropyridine derivative resulting from the reaction of
