  activity of a series of 3-(1-substituted pyridinium-4-thiomethyl)-7 alpha-formamido cephalosporins is described. All the derivatives showed good potency and stability to bacterial beta-lactamases. The antibacterial efficacy seen with the N-alkyl pyridinium substituents was enhanced by the introduction of a catecholic side chain at C-7 and by preparation of N-(substituted amino)pyridinium derivatives

  A series of cephalosporins containing a novel 7-[2-(Z)-(2-amino-thiazol-4-yl)-3-(dimethoxyphosphoryl)-acryloylamino] group were prepared and their antibacterial activity measured against a range of pathogens. In general the compounds displayed a broad spectrum of activity against both Gram positive and Gram negative organisms, except Pseudomonas aeruginosa. Activity against the latter could be achieved by introducing a catechol moiety at the 3 position of the cephalosporin. The methyl phosphonates in general were stable to a wide range of β-Mactamases, including the TEM enzymes and the Enterobacter cloacae P99 chromosomal enzyme. In addition, they showed the advantage of being highly water soluble.
