Design and synthesis of new cephalosporin antibiotics
摘要:
Cephalosporins are important antibiotics. We synthesized new cephalosporin analogs containing novel side chains of methyl, propyl, benzyl, and phenoxy groups. Four synthetic methods with N-alkylation and N-acylation at position C-7 and esterification at position C-4 of 7-aminodesacetoxycephalosporanic acid are reported here.
two series of novelcephalosporins that are bactericidal to Mycobacterium tuberculosis alone of the pathogens tested, which only kill M. tuberculosis when its replication is halted by conditions resembling those believed to pertain in the host, and whose bactericidal activity is not dependent upon or enhanced by clavulanate, a β-lactamase inhibitor. The two classes of cephalosporins bear an ester or
