The present invention provides a phenanthroline derivative of formula (I)
wherein, for example,
R1 is hydrogen, carboxy, cyano, nitro, (1-4C)alkyl, (1-6C)alkoxycarbonyl, (1-4C)alkylamino, (2-4C)alkanoyl, (1-4C)alkoxy-(2-4C)alkoxy-(2-4C)alkoxycarbonyl or N-[amino-(2-8C)alkyl]carbamoyl;
R2 is, for example, hydrogen, carboxy, (1-6C)alkoxycarbonyl, carbamoyl, N-(1-8C)alkylcarbamoyl, N,N-di-(1-8C)alkylcarbamoyl, N-(1-4C)alkylcyclohexylcarbamoyl, 1,2,3,4-tetrahydro-isoquinolin-2-ylcarbonyl or N,N-[di-(1-4C)alkyl]thiocarbamoyl;
R3 and R4, which may be the same or different, are, for example, hydrogen or halo; and
R5 is, for example, hydrogen, di-(1-4C)alkylamino or halo; or a pharmaceutically-acceptable salt thereof.
The invention further provides pharmaceutical compositions comprising phenanthroline derivatives, processes for making the same and their use in producing an anti-fibroproliferative effect.
