<p>Compounds of formula (I): <CHEM> are described wherein R represents a -CONHOH, carboxyl (-CO2H) or esterified carboxyl group; R<1> represents an optionally substituted alkyl, alkenyl, aryl, aralkyl, heteroaralkyl or heteroarylthioalkyl group;R<2> 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; R<3> represents a hydrogen atom or an alkyl group;R<4> represents a hydrogen atom or an alkyl group; R<5> represents a group -[Alk]nR<6> where Alk is an alkyl or alkenyl group optionally interrupted by one or more -O- or -S- atoms or -N(R<7>)- groups [where R<7> is a hydrogen atom or a C1-6alkyl group], n is zero or an integer 1, and R<6> 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.</p> |
