The invention relates to a group of new 1-[2H-1-benzopyran-2-one-8-yl]-piperazine derivatives having interesting pharmacological properties due to 5-HT1A agonism and 5-HT1D-antagonism.
The compounds have the general formula (1)
wherein
R₁ is alkyl (1-4C), alkoxy (1-4C), hydroxy, alkoxy(1-4C)alkyl(1-4C), pyrrolidinyl, piperidinyl, morpholinyl, halogen, cyano, trifluoromethyl, amino, or mono- or disubstituted amino wherein the substituents are alkyl (1-4C), or alkyl(1-4C)carbonyl,
m has the value 0, 1 or 2,
R₂ is alkyl (1-4C), alkoxy (1-4C), halogen or trifluoromethyl,
n is 0 or 1, on the understanding that m + n is at least 1,
R₃ is hydrogen, alkyl (1-3C) or alkenyl (2-3C),
R₄ is alkyl (1-4C), and
p has the value 0, 1 or 2, and pharmaceutically acceptable acid addition salts thereof.
The compounds can be used for the treatment of affections or diseases of the central nervous system caused by disturbances of the serotonergic transmission.
