摘要: The 11,12-cyclic carbazate of 3-keto-6-O-methylerythromycin A (4) was prepared. This compound shows in vitro antibacterial activity comparable to erythromycin (1) against erythromycin-susceptible organisms and increased some erythromycin-resistant organisms. Using 4 as a lead, series analogues prepared by acylation or alkylation the nitrogen. Several N-alkylated derivatives showed dramatically improved both susceptible resistant compared A.
