, (2008/06/13)
Compounds which are clinically important cephalosporins and salts and esters thereof having a wide spectrum of activity against Gram-positive bacteria but especially against Gram-negative bacteria such as Pseudomonas spp. against which commercially available cephalosporins are normally inactive. Preferred compounds of the invention are also active against Gram-negative cephalosporinase-producing organisms such as Enterobacter spp., Serratia spp. and indole-positive Proteus; methods of preparation are described.

Cephalosporins of the formula STR1 their pharmaceutically-acceptable, nontoxic salts, and hydrates thereof are produced, wherein A is hydrogen; unsubstituted or substituted alkyl; aryl; or R1 --X--, wherein X is --CO-- or --SO2 --, and R1 is hydrogen, unsubstituted or substituted alkyl; aryl; thienyl; furyl; amino; alkylamino; dialkylamino; pyrrolidyl; or piperidyl; Or when X is --CO--, R1 can also be alkoxy; B is phenyl, methylphenyl, chlorophenyl, hydroxyphenyl or the moiety STR2 E is hydrogen, hydroxyl or acetoxy; and C is a center of chirality. These compounds are particularly useful for their antimicrobial and, particularly, antibacterial effects.
