Beta-lactam antibacterial agents, their pharmaceutical compositions and process for their preparation |
| abstract |
The compounds of the formula (I):wherein R<sup>1</sup> is a hydrogen atom, a trityl group or an acyl group as found in known antibacterially active penicillins or cephalosporins; R<sup>2</sup> is a hydrogen atom, a lower alkyl group or an aryl group; R<sup>3</sup> is a hydrogen atom, a lower alkyl group, a substituted lower alkyl or a thiosubstituted lower alkyl group; and R<sup>4</sup> is a group such that COzR<sup>4</sup> is a carboxylic acid group or a salt or readily removable ester thereof; are antibiotics. The compounds may be formulated in pharmaceutical compositions.Processes for the preparation of the compounds (I) are also described. |
