ABSTRACT:
The present invention provides novel compounds of the general Formula (I) as ligands to the melanocortin receptors and/or for treatment of disorders in the melanocortin system:wherein X is (CH2)nwhere n is 0, 1 or 2;R1, R2, R3, R4and R5may be the same or different and are selected from hydrogen, halogen, alkyl having 1 to 5 carbon atoms, alkoxy having 1 to 5 carbon atoms, hydroxy, alkylsulphonyloxy, cyano, nitro, trihaloalkyl, sulpho or one of the structures given in Scheme 1; or two of R1, R2, R3, R4and R5may together form a methylenedioxy or ethylenedioxy moiety;R6, R7, R8and R9are the same or different and are selected from hydrogen, halogen, alkyl having 1 to 5 carbon atoms, alkoxy having 1 to 5 carbon atoms, hydroxy, amines (primary, secondary or tertiary) having 0, 1 or 2 carbon atoms, cyano, nitro, trihaloalkyl, amide or sulpho, and z where shown represents the point of attachment of the residue to the phenyl or pyrrole ring;and the pharmacologically active salts thereof.
