2114623 9324475 PCTABS00028 Compounds of formula (1) are described wherein R represents a -CONHOH, carboxyl (-CO2H), esterified carboxyl or -P(O)(X1R8)X2R9 group, where X1 and X2, which may be the same or different is each an oxygen or a sulphur atom, and R8 and R9, which may be the same or different each represents a hydrogen atom or an optionally substituted alkyl, aryl or aralkyl group; R1 represents a hydrogen atom or 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 an optionally substituted alkyl or alkenyl group optionally interrupted by one or more -O- or -S- atoms of -N(R7)- groups, [where R7 is a hydrogen atom or a C1-6 alkyl group] or 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, n is zero or an integer 1, and R6 is an optionally substituted cycloalkyl or cycloalkenyl group; X represents a group -NR10R11 where R10 is a hydrogen atom or an optionally substituted alkyl, alkanoyl, aryl, aroyl, aralkyl or aralkanoyl group, and R11 is a straight or branched alkylaminosulphonylamino group wherein the alkyl portion is optionally interrupted by one or more -O- or -S- atoms or N(R7)- or aminocarbonyloxy groups; and the salts, solvates and hydrates thereof. The compounds are metalloproteinase inhibitors and in particular have a selective inhibitory action against gelatinase and may be of use in the treatment of cancer to control the development of tumour metastases.
