A compound of formula (I)
wherein carbons 1 and 2 are joined by either a single or a double bond;
R1 is hydrogen or methyl;
R2 is hydrogen or methyl;
R3 is (A)
wherein R4 and R5 are independently hydrogen, straight or branched alkyl of 1 to 6 carbon atoms, straight or branched alkoxy of 1 to 6 carbon atoms, trifluoromethyl, cyano, halogen, phenyl (optionally substituted with one or more halogens), or when R4 and R5 are on adjacent carbons, taken together form a fused 5, 6 or 7 member ring optionally containing one or more oxygen or sulfur atoms;
W and Z are methylene groups which taken together with the carbon to which they are attached form a saturated, 3 to 12 member ring system optionally:
1) substituted independently with one or more lower alkyl groups,
2) containing an oxygen or sulfur atom,
3) two said methylene groups of said 3 to 12 member ring are joined with a (C1-6) alkylene group to form a bicyclic ring system; and
X is hydrogen or halogen;
or a pharmaceutically acceptable solvate thereof.
