Abstract

Abstract Penicillins of the formula ##EQU1## or pharmaceutically acceptable non-toxic salts thereof, wherein C* is a carbon atom constituting a center of chirality; A is a moiety of the formula ##EQU2## or ##EQU3## wherein X is ##EQU4## Y is ##EQU5## or wherein Aryl is an aryl moiety; Z is ##EQU6## Q 1 is ##EQU7## or ##SPC1## Q 2 is ##EQU8## ##SPC2## or ##SPC3## R is straight- chain or branched alkyl of 1 to 5 carbon atoms; R 1 is alkyl of 1 to 10 carbon atoms, cycloalkyl of 3 to 10 carbon atoms, alkenyl of 2 to 10 carbon atoms, cycloalkenyl of 3 to 10 carbon atoms. vinyl, arylvinyl, mono-, di-, or tri-halo-lower alkyl, H 2 N--, R--NH--, (R) 2 N--, aryl--NH--, aryl-lower alkylamino, alkoxy of 1 to 8 carbon atoms, aralkoxy of 1 to 8 carbon atoms in the alkoxy portion, cycloalkoxy of 3 to 7 carbon atoms, aryloxy, R--O--V--, R--S--V--, N=C--V--, R--O--CO--V--, H 2 N--CO--V--, R--NH--CO--V--, R--O--CO--NH--, R--SO 2 --NH--, (R) 2 N--CO--V--, wherein R is as above defined, ##SPC4## ##SPC5## provided that when X is --SO 2 --, R 1 is not alkoxy, aralkoxy, cycloalkoxy or aryloxy, and further provided that R 1 can also be hydrogen when X is --CO--; V is a divalent organic radical of 1 to 3 carbon atoms; n is 0, 1 or 2; R 2 and R 3 are the same or different and are each hydrogen, alkyl of 1 to 8 carbon atoms, alkenyl of 2 to 8 carbon atoms, vinyl, allyl, propenyl, cycloalkyl of 3 to 6 carbon atoms, cycloalkenyl of 3 to 6 carbon atoms, mono-, di- or tri-halo lower alkyl or aryl; R 4 , r 5 and R 6 are the same or different and are each hydrogen, nitro, cyano, (R) 2 N--, (R) 2 N--CO--, R--CO--NH--, R--O--CO--, R--CO--O--, R--, R--O--, wherein R is as above defined, H 2 N--SO 2 --, chlorine, bromine, iodine, fluorine or trifluoromethyl; G is hydrogen or straight or branched chain alkyl of 1 to 5 carbon atoms; and B is a moiety of the formula ##SPC6## wherein R 7 , r 8 and R 9 are the same or different and are each hydrogen, halogen, nitro, hydroxy, R--, R--O--, R--S--, R--SO-- , R--SO 2 --, (R) 2 N--, R--CO--NH--, or R--CO--O-- , wherein R is as above defined; the arrow in the divalent linking group ←Q 2 → means that the linkage of two atoms by the free valencies of this group must take place as indicated by the arrow; exhibit activity against both Gram-positive and Gram-negative bacteria.
