A series of the novel oleandomycin 9-oximes has been prepared and characterized by spectroscopic data and X-ray analysis. The antibacterial in vitro activities of the oximes (6-10) were compared with that of oleandomycin (1). Among the novel derivatives the most active compound was 8(R)-rriethyloleandomycin-9-oxime (9) in contrast to its 8(S)-isomer (10) which possessed only low potency. Some preliminary pharmacokinetic data of 9 confirmed its activity. Compound 9 has been advanced to further biological study.
