FIELD: biologically active compounds. SUBSTANCE: invention provides novel carbapenem derivatives having general formula I: (I) wherein R1 and R2, identical or different, denote each modified group, which can be hydrolyzed inside body, selected from 1-alkanoyloxyalkyl, 1-alkoxycarbonyloxyalkyl, 5- methyl-1,3-dioxolen-2-on-4-ylmethyl; R3 and R4, identical or different, denote each lower alkyl or, together with adjacent nitrogen atom, form cyclic amine structure; or pharmaceutically acceptable salts thereof. Antibacterial agent contains carbapenem derivative of formula I and pharmaceutically acceptable excipient or diluent. Above-mentioned intermediate represents carbapenem derivative depicted by general formula II: (II) wherein R2 modified group, which can be hydrolyzed inside body, selected from 1-alkanoyloxyalkyl, 1-alkoxycarbonyloxyalkyl, 5-methyl-1,3-dioxolen-2-on-4-yl-methyl; R3 and R4, identical or different, denote each lower alkyl or, together with adjacent nitrogen atom, form cyclic amine structure; and R5 denotes hydrogen or carboxyl-protective group selected from p-nitrobenzyl, p-methoxybenzyl, and diphenylmethyl; or its salt. EFFECT: extended choice of antibacterial drugs. 19 cl, 3 tbl, 13 ex
