چکیده

Synthesis and biological activity of a series of 7^[(Z)-2-(2-aminothiazol-4-yl)-3-(substituted)2-propenoylamino]-3-cephem-4-carboxylic acids and their pivaloyloxymethyl esters are described. These acid compounds exhibited potent antibacterial activity against both Gram-positive and Gram-negative bacteria. Pivaloyloxymethyl esters of selected compounds in this series were found to be well absorbed from small intestine in mice. 453
