ABSTRACT:
There is disclosed compounds and pharmaceutical compositions having a xanthine core and one or two hydrocarbon side chains bonded to a ring nitrogen atom, wherein the hydrocarbon side chains are independently a straight chain hydrocarbon having at least one double bond in a carbon chain length of from about 4 to about 18 carbon atoms in length, wherein multiple double bonds are separated from each other by at least three carbon atoms, and wherein the hydrocarbon chain may be substituted by a hydroxyl, halo or dimethylamino group and/or interrupted by an oxygen atom. The compounds lower elevated levels of unsaturated, non-arachidonate phosphatidic acid (PA) and diacylglycerol (DAG) derived from said PA within seconds of the primary stimulus and their contact with cells. The modulatory effect depends on the nature of the target cell and the stimulus applied.
