The compounds of formula (I): [in which R1 represents a hydrogen atom or an alkyl group containing 1 to 3 carbon atoms; R2 represents a cycloalkyl group containing 3 to 6 carbon atoms; R4 represents a halogen atom, a nitrile group, a nitro group, an -SCH3 group, a C1-6 alkylcarbonyl group, a C3-6 cycloalkylcarbonyl group, a -CX3 group, a -WCX3 group, a -(CH2)nCX3 group, a -(CX2)n CX3 group, a -W(CX2)nCX3 group or a -W(CH2)nCX3 group, in which X represents a halogen atom, W represents an oxygen or sulphur atom and n represents 1, 2 or 3; and R5 represents a hydrogen atom, an alkyl group containing 1 to 3 carbon atoms or a cycloalkyl group containing 3 to 6 carbon atoms; provided that, if R5 represents a hydrogen atom, R4 does not represent an -SCH3 or -CF3 group]; and their salts have an anti-proliferative, anti-inflammatory and anti-tumour activity. A description is also given of processes for their preparation, of the compositions which contain them and of their use in therapeutics.
