Disclosed are compounds of formula (I) or pharmaceutically acceptable salts thereof wherein: R1 is not 3-fluorobenzyl and represents (C2-C6) alkenyl, aryl (C1-C6)alkyl or heteroaryl (C1-C6)alkyl, OR7, O(CH2)nC(O)R7, O(CH2)nNR7R8, O(CH2)nCO2R7, NR7COR8, COR7, CONR7R8 or CO2R7; R2 represents hydrogen, hydroxy, halogen, trifluoromethyl, trifluoromethoxy, amino (C1-C6)alkyl, mono- or di(C1-C6)alkylamino (C1-C6), or mono- or di(C1-C6)alkylamino(C1-C6)alkoxy; or OR7, O(CH2)nC(O)R7, O(CH2)nNR7R8, O(CH2)nCO2R7, NR7COR8, COR7, CONR7R8 or CO2R7; R3 represents (C1-C6)alkyl; R4 represents halogen or trifluoromethyl; R5 and R6 represent hydrogen, trifluoromethyl, triluoromethoxy, cyano, (C1-C6)alkyl, halogen, (C1-C6)alkylamino(C1-C6)alkyl, mono or di(C1-C6)alkylamino(C1-C6), or mono- or di(C1-C6)alkylamino(C1-C6)alkoxy; or together form a 5 or 6 membered aromatic ring which is optionally substituted. X represents a bond or CH2 which is optionally mono- or disubstituted with a (C1-C6)alkyl or (C1-C6)alkoxy; and A, B, C and D are the same or different and represent CRp or N with the proviso that not more than two of A,B, C and D represent N; which compounds are selective modulators of Bradykinin B2 receptors. |
