K. Ishikura et al., SYNTHESIS AND STRUCTURE-ACTIVITY-RELATIONSHIPS OF 2-PROPENOYLAMINO]-3-DESACETOXYMETHYLCEPHALOSPORINS, Journal of antibiotics, 47(4), 1994, pp. 453-465
Synthesis and biological activity of a series of 7 beta-[(Z)-2-(2-amin
othiazol-4-yl)-3-(substituted)- 2-propenoylamino]-3-cephem-4-carboxyli
c acids and their pivaloyloxymethyl esters are described. These acid c
ompounds exhibited potent antibacterial activity against both Gram-pos
itive and Gram-negative bacteria. Pivaloyloxymethyl esters of selected
compounds in this series were found to be well absorbed from small in
testine in mice.
