There are provided compounds of the formula (I)
wherein R₇ is a halogen or a C₁-C₄ alkoxy group; R4 is a substituted alkyl group CHR'-CHR''Y, or an alkenyl group CR'=CHY, wherein R' and R'' each represent, independently, hydrogen or an unsubstituted or substituted C₁-C₇ straight or branched alkyl, phenyl or benzyl group or R' and R'', taken together with the carbon atoms to which they are attached, form a five membered or six membered ring of the formulae
wherein Y is an electron-withdrawing group and A is hydrogen or a carboxy group; R is hydrogen, a C₁-C₇ straight or branched alkyl, or an unsubstituted or substituted benzyl or diphenylmethyl group; R₃ is methyl or a C₁-C₄ alkoxymethyl group; and R₂ is hydrogen or a group R₄ as defined above.
The compounds of formula (I) are endowed with elastase inhibitory activity, and can be used for the treatment of inflammatory and degenerative diseases. A process for their preparation, and pharmaceutical compositions containing them, are also provided.
