The synthesis and microbiological evaluation of a new series of 3-thiazol-4-yl-carba-1-dethiacephalosporins is described. Structure activity relationship was achieved by changing substitution at the 2-position of the thiazole moiety. The result was a marked variance of microbiological activity in the C7 side-chain derivatives. ATMO derivatives possess potent activity against both Gram-positive and Gram-negative bacteria. For example, MICs (μg/ml) of LY215226 against representative organisms are as follows: S. aureus 0.25, S. pneumoniae 0.008, H. influenzae 0.008, E. coli 0.25, K. pneumoniae 0.008, E. cloacae 0.5, S. typhi 0.25, and M. morganii 0.25.

of fused-thiazole derivatives of nootkatone have been synthesized, and these new compounds were tested against several strains of bacteria. Some of these compounds are found to be potentantimicrobialagents against Staphylococcus aureus and Enterococcus faecium with minimum inhibitory concentration (MIC) values as low as 1.56 μg/mL. The lead compound is bactericidal and very potent against S. aureus
