Mezlocillin, 6--penicillanic acid, is a new semisynthetic acylureido-penicillin with a broad spectrum of antibacterial activity.The synthesis of mezlocillin from ampicillin and the from 6-aminopenicillanic acid and the physico-chemical properties are described.Mezlocillin is cleaved by penicillinase to the penicilloate which is degraded further by acids to the penilloate. - Key words: Acylureido series; Mezlocillin, chemical properties, synthesis; Penicillins

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.
