Pyrimidones of formula (I) are inhibitors of the enzyme LpPLA2 and thereof use in treating inter alia atherosclerosis,
in which:
R1 is COOH or a salt thereof, COOR10, CONR11R12, CN or CH2OH;
R2 is a mono- or bicyclic aromatic ring system or a mono- or bicyclic heteroaromatic ring system;
R3 is C1-20alkyl, C3-6cycloalkyl, C3-6cycloalkylC1-5alkyl, C1-10alkoxyC1-10alkyl, or an aromatic or heteroaromatic ring system;
W is SO2 or a bond;
X is O or S; and
Y is a group of the formula A1—A2—A3 in which A1 and A3 each represent a bond or a straight chain or branched alkylene group, said alkylene group(s) containing a total of 1 to 10 carbon atoms and A2 represents a bond or O, S, SO, SO2, CO, C═CH2, CONH, NHCO, CR15R16, CH═CH or C═C, providing that when A2 is O, S, SO, SO2 or CONH, A3 contains at least two carbon atoms linking the A2 group and the CH2 group in formula (I).
