Abstract

Abstract A pharmaceutical compound of the formula ##STR1## in which n is 0, 1 or 2 and R 1 is attached at any of the positions 5, 6, 7, 8, 9 or 10, and each R 1 is halo, trifluoromethyl, C 1-4 alkoxy, hydroxy, nitro, C 1-4 alkyl, C 1-4 alkylthio, hydroxy-C 1-4 alkyl, hydroxy-C 1-4 alkoxy, trifluoromethoxy, carboxy, --COOR 5 where R 5 is an ester group, --CONR 6 R 7 or --NR 6 R 7 where R 6 and R 7 are each hydrogen or C 1-4 alkyl; R 2 is phenyl, naphthyl or heteroaryl selected from thienyl, pyridyl, benzothienyl, quinolinyl, benzofuranyl or benzimidazolyl, said phenyl, naphthyl and heteroaryl groups being optionally substituted, or R 2 is furanyl optionally substituted with C 1-4 alkyl; R 3 is nitrile, carboxy, --COOR 8 where R 8 is an ester group, --CONR 9 R 10 where R 9 and R 10 are each hydrogen or C 1-4 alkyl, or R 11 SO 2 -- where R 11 is C 1-4 alkyl or optionally substituted phenyl; and R 4 is --NR 12 R 13 , --NHCOR 12 , --N(COR 12 ) 2 or --N═CHOCH 2 R 12 where R 12 and R 13 are each hydrogen or C 1-4 alkyl optionally substituted with carboxy, ##STR2## where X is C 2-4 alkylene, or --NHSO 2 R 14 where R 14 is C 1-4 alkyl or optionally substituted phenyl; provided that when n is 0, R 3 is nitrile and R 4 is --NH 2 , R 2 is not phenyl or phenyl substituted in the para-position with a single chloro, hydroxy or methoxy substituent; and salts thereof.
