M. Kume et al., ORALLY ACTIVE CEPHALOSPORINS .4. SYNTHESIS, ANTIBACTERIAL ACTIVITY AND ORAL ABSORPTION OF H-1,2,3-TRIAZOL-4-YL)THIOMETHYLTHIO-CEPHALOSPORINS, Chemical and Pharmaceutical Bulletin, 41(4), 1993, pp. 758-762
The synthesis, antibacterial activity and oral absorption of -triazol-
4-yl)thiomethylthio-3-cephem-4-carboxylic acids with various C-7 side
chains (2) are described. The (1H-1,2,3-triazol-4-yl)thiomethylthio C-
3 side chain was found to be an effective substituent for good oral ab
sorption of cephalosporins with some C-7 side chains.
