ANTINEURODEGENERATIVE ERGOLINE DERIVATIVES

摘要

The present invention provides the new use in the treatment of neurodegenerative diseases with ergoline derivatives of formula (I) wherein R1 represents a hydrogen atom or a linear or branched C1-C5 alkyl or C2-C5 alkenyl group optionally substituted with a C3-C7 cycloalkyl, a hydroxy group or a R3-substituted phenyl group wherein R3 is a hydroxy or a hydroxymethyl group; R2 represents a hydrogen atom or a linear or branched C1-C5 alkyl or a C2-C5 alkenyl group optionally substituted with a hydroxy group, or a R3-substituted phenyl group wherein R3 is as above defined, or with a C1-C5 alkoxy group; the symbols -- at positions 2,3 and 8, 9 independently denote a single or double chemical bond and Z represents a group (CH2)nOH, wherein n is 0 or an integer from 1 to 3, or a group C(R4)2OH wherein R4 is a C1-C5 alkyl or a phenyl group, or a pharmaceutically acceptable salt thereof. Some compounds of formula (I) are novel. Processes for their preparation and pharmaceutical compositions containing them are also described.
