Novel antibacterial amide compounds and process means for producing the same

Novel organic amide compounds which are N-[6-[(substituted amino)phenyl]-1,2-dihydro-2-oxonicotinyl]penicillin and cephalosporin type compounds having broad spectrum antibacterial utility are provided by (a) reacting the free amino acid of the appropriate penicillin or cephalosporin or the acid salt or silylated derivative thereof with a reactive derivative of the corresponding N-6-[(substituted amino)phenyl]-1,2-dihydro-2-oxonicotinic acid or (b) reacting the free amino acid 6-amino-penicillanic acid, 7-aminocephalosporanic acid, 7-amino-3-methylceph-3-em-4-carboxylic acid or a related compound or the acid salt or silylated derivative thereof with a reactive derivative of the corresponding D-N-[6-[(substituted amino)phenyl]-1,2-dihydro-2-oxonicotinyl]-2-substituted glycine. Pharmaceutical compositions containing said compounds and methods for treating infections using said compositions are also disclosed.
