Patent ID: 7163957

Claim:
A compound having the formula (1) in which: (a) represents a single bond or a double bond; W represents a CH, CH 2 , CHCH 3 , CCH 3 or C(CH 3 ) 2 group, a C(CH 2 ) 2 group (i.e. a carbon atom bearing two methylene groups linked together so as to form a spiro-cyclopropane unit) or a C(CH 2 ) 3 group (i.e. a carbon atom bearing two methylene groups linked to another methylene group so as to form a spiro-cyclobutane unit) with the proviso, however, that when (a) is a double bond, then W exclusively represents a OH or CCH 3 group, and that when (a) is a single bond, then W exclusively represents a CH 2 , CHCH 3 , C(CH 3 ) 2 , C(CH 2 ) 2 or C(CH 2 ) 3 group; X is a carbon atom bearing a hydrogen atom (CH); and Y is a hydrogen atom or a fluorine atom; or an addition salt or hydrate thereof with a pharmaceutically acceptable inorganic acid or organic acid or a tautomeric form, pure enantiomer or mixture of racemic or nonracemic enantiomers thereof.
