A pharmaceutical compound of the formula
in which n is 0, 1 or 2 and R¹ is attached at any of the positions 5, 6, 7, 8, 9 or 10, and each R¹ is halo, trifluoromethyl, C₁₋₄ alkoxy, hydroxy, nitro, C₁₋₄ alkyl, C₁₋₄ alkylthio, hydroxy-C₁₋₄ alkyl, hydroxy-C₁₋₄ alkoxy, trifluoromethoxy, carboxy, -COOR⁵ where R⁵ is an ester group, -CONR⁶R⁷ or -NR⁶R⁷ where R⁶ and R⁷ are each hydrogen or C₁₋₄alkyl;
R² is phenyl, naphthyl or heteroaryl selected from thienyl, pyridyl, benzothienyl, quinolinyl, benzofurangyl or benzimidazolyl, said phenyl, naphthyl and heteroaryl groups being optionally substituted, or R² is furanyl optionally substituted with C₁₋₄ alkyl;
R³ is nitrile, carboxy, -COOR⁸ where R⁸ is an ester group, -CONR⁹R¹⁰ where R⁹ and R¹⁰ are each hydrogen or C₁₋₄ alkyl, or R¹¹SO₂- where R¹¹ is C₁₋₄ alkyl or optionally substituted phenyl; and
R⁴ is -NR¹²R¹³, -NHCOR¹², -N(COR¹²)₂ or -N=CHOCH₂R¹² where R¹² and R¹³ are each hydrogen or C₁₋₄ alkyl optionally substituted with carboxy,
where X is C₂₋₄ alkylene, or -NHSO₂R¹⁴ where R¹⁴ is C₁₋₄ alkyl or optionally substituted phenyl;
provided that when n is 0, R³ is nitrile and R⁴ is -NH₂, R² is not phenyl or phenyl substituted in the para-position with a single chloro, hydroxy or methoxy substituent;
and salts thereof.
