6-O-Methylerythromycin B has been synthesized from erythromycin B via regioselective methylation of the 6-hydroxyl group in 71% overall yield. This compound shows in vitro antibacterial activity comparable to erythromycins A and B and exhibits superior in vivo activity with improved
M S Brown et al.
The Journal of antibiotics, 52(8), 742-747 (1999-12-02)
Cyclopropane carboxylic acid was fed to Saccharopolyspora erythraea NRRL 18643 (6-deoxyerythromycin producer), resulting in the production of 6-deoxy-13-cyclopropyl-erythromycin B. These studies provide further evidence that deoxyerythronolide B synthase has a relaxed specificity for the starter unit.

Letters in applied microbiology, 52(2), 129-137 (2010-12-24)
To overproduce erythromycin C, B or D and evaluate the effect of disruption of tailoring genes eryK and eryG in an industrial erythromycin producer. The tailoring genes eryG and eryK were inactivated individually or simultaneously by targeted gene disruption in
M N Mordi et al.
Journal of medicinal chemistry, 43(3), 467-474 (2000-02-12)
One of the major drawbacks in the use of the antibiotic erythromycin A is its extreme acid sensitivity, leading to degradation in the stomach following oral administration. The modern derivative clarithromycin degrades by a different mechanism and much more slowly.

Rapid communications in mass spectrometry : RCM, 21(2), 237-246 (2006-12-16)
A rapid and simple sample preparation procedure for determining residues of antibiotics of the class of macrolides and lincomycin in whole milk and yoghurt by liquid chromatography/tandem mass spectrometry (LC/MS/MS) is presented. The method is based on the matrix solid-phase
