Ergolinyl compounds which are nitrogen-substituted in the 8-position and have Formula (I)
and physiologically compatible salts thereof, wherein
(a) R1 is hydrogen, the 8-substituent can be in the a- or β-position and
represents a single or a double bond,
R2 is hydrogen, C1 4-alkyl or C1 7-acyl,
R3 is hydrogen, chlorine or bromine, and
R4 is C1-6-alkyl, C3-6-cycloalkyl-C1-3-alkyl, C3 6-alkenyl, or C3-6-alkynyl; or
(b) R1 is
and the 8-substituent can be in the a- or β-position,
represents a single or double bond,
R2, R3 are as defined above,
R4, is C1-6-alkyl, C3-6-cycloalkyl-C1-3-alkyl, C3 alkenyl, or C3-6-alkynyl; and
R5 is hydrogen, C1 10-alkyl, C3 10-alkenyl, or C3 10- alkynyl, and
