<p>A compound of formula (I) <CHEM> wherein carbons 1 and 2 are joined by either a single or a double bond; R<1> is hydrogen or methyl; R<2> is hydrogen or methyl; R<3> is (A) <CHEM> wherein R<4> and R<5> 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 R<4> and R<5> 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.</p> |
