Midecamycin
Midecamycin is a naturally occurring 16-membered macrolide that fits under the category of acetoxy-substituted macrolide antibiotics. In this molecule, an acetoxy group is substituted on the position 9 of the 16-member ring and on position 4 of the terminal sugar. Until 2017, midecamycin was still under the list of approved antimicrobial active pharmaceutical ingredients by Health Canada.
