Thiol derivative compounds, pharmaceutically acceptable salts, and biolabile esters thereof, useful for inhibiting metallo-β-lactamases, bacterial enzymes which confer resistance to clinically relevant ß-lactam antibiotics, characterized by general formula (I): wherein: R1 is selected from straight, branched, unsaturated or alicyclic alkyl, optionally substituted with from 1 to 3 R¿x? groups; and (CH2)nAr, where Ar is an aryl selected from the group consisting of phenyl, furanyl, thienyl, pyridyl, naphthyl, biphenyl, dibenzofuranyl, dibenzothienyl, fluorenyl and fluorenonyl, where n is 0, 1, 2 or 3, and where Ar is optionally substituted with 1 to 3 Rx groups; R?2¿ is selected from hydrogen; and a group of formula (II): wherein: R3 is selected from hydrogen; straight, branched, unsaturated or alicyclic alkyl, optionally substituted with from 1 to 3 R¿x? groups; (CH2)nAr, where Ar is an aryl selected from phenyl, furanyl, thienyl, pyridyl, naphthyl, biphenyl dibenzofuranyl, dibenzothienyl, fluorenyl and fluorenonyl, where Ar is optionally substituted with 1 to 3 Rx groups, and where n is 0, 1, 2 or 3; and a group of formula (III): wherein: R?4¿ is selected from hydrogen; and straight or branched alkyl; R5 is selected from hydrogen; straight, branched, unsaturated or alicyclic alkyl, optionally substituted with 1 to 3 R¿x? groups, where the alkyl group is optionally interrupted by X, where X is selected from O, S, NH and N(COCH3); allyloxy and 9-fluorenylmethyloxy; and (CH2)nAr, where Ar is selected from phenyl, furanyl, thienyl, pyridyl, naphthyl, biphenyl, dibenzofuranyl, dibenzothienyl, fluorenyl and fluorenonyl, where n is 0, 1, 2 or 3, and where Ar is optionally substituted with 1 to 3 Rx groups; and Rx is selected from OR, CN, C(O)NH2, C(O)NHR, C(O)N(R)2, OC(O)NH2, OC(O)R, CHO, SO2NH2, SOR, CF3, C(O)R, COOR, F, Cl, Br, I, OCH2Ph, NHR, N(R)2, NHCOR, NHCO2t-Bu, NHCO2allyl, NH2, and R, where R is hydrogen, C1 to C15 alkyl, or aryl. The invention is further directed to a pharmaceutical composition containing the compound, as well as a method for treating bacterial infections in animals or humans, wherein the composition can be administered in combination with a β-lactam antibiotic.
