Abstract

The present invention provides novel tetrahydrocarbazole derivatives which have improved properties and which can be employed as inhibitors of GPCRs. This results in the possibility of using the novel compounds to treat pathological conditions whose severity depends on the pathobiochemical effect of GPCRs. The compounds of the invention act in particular via an antagonistic inhibition of the LHRH receptor. The invention further provides medicaments which comprise one or more of the novel compounds as active ingredient. The medicaments are suitable in particular to be employed in an oral dosage form for a mammal, in particular a human.
