【Abstract】 Nine new 9-substituted acyl hydrazone clarithromycin derivatives were synthesized from clarithromycin. The antibacterial activities of the title compounds were tested in vitro and the results showed that these compounds exhibited good antibacterial activities against the tested gram-positive bacteria including Staphylococcus albus, Diplococcus lanceolatus and Enterococcus. Some of the compounds were also rather actived against Staphylococcus aureus and Gamma streptococcus.更多还原
