Compounds of formula (I):
are described wherein R represents a -CONHOH, carboxyl (-CO₂H) or esterified carboxyl group; R¹ represents an optionally substituted alkyl, alkenyl, aryl, aralkyl, heteroaralkyl or heteroarylthioalkyl group;R² represents an optionally substituted alkyl, alkenyl, cycloalkyl, cycloalkylalkyl, aryl, aralkyl, aralkoxy, or aralkylthio group, or an amino (-NH₂), substituted amino, carboxyl (-CO₂H) or esterified carboxyl group; R³ represents a hydrogen atom or an alkyl group;R⁴ represents a hydrogen atom or an alkyl group; R⁵ represents a group -[Alk]nR⁶ where Alk is an alkyl or alkenyl group optionally interrupted by one or more -O- or -S- atoms or -N(R⁷)- groups [where R⁷ is a hydrogen atom or a C₁₋₆alkyl group], n is zero or an integer 1, and R⁶ is an optionally substituted cycloalkyl or cycloalkenyl group; X represents an amino (-NH₂), or substituted amino, hydroxyl or substituted hydroxyl group; and the salts, solvates and hydrates thereof.
The compounds are metalloproteinase inhibitors and in particular have a selective gelatinase action, and may be of use in the treatment of cancer to control the development of tumour metastasises.
