Question: are clindamycin and clarithromycin related?
Answer: Chloramphenicol and macrolides such as erythromycin, clarithromycin, and azithromycin also act at the 50s ribosomal subunit and may compete for binding at this site. Clindamycin and the related drug lincomycin are often discussed along with the macrolides but are not chemically related.
