1. a chemical compound characterized by a large lactone ring containing multiple keto and hydroxyl groups.
2. any of a group of antibacterial antibiotics containing such a ring linked to one or more sugars.
A natural lactone with a large ring; usually consisting of 14-20 atoms; macrolides include a class of antibiotics discovered in streptomycetes, for example, erythromycin; macrolides also inhibit protein biosynthesis.
1. a compound characterized by a large lactone ring with multiple keto and hydroxyl groups.
2. any of a group of antibiotics containing this ring linked to one or more sugars, produced by certain species of Streptomyces.
A class of antibiotics that are produced by certain actinomycetes of the genus Streptomyces, are characterized by a large lactone ring linked to one or more sugars, and act by inhibiting protein synthesis.
macrolideA natural lactone with a large (14–20) carbon ring structure that inhibits protein synthesis; e.g., erythromycin.
A natural lactone, with a large ring, usually of 14-20 atoms; several antibiotics, including erythromycin, are macrolides. They inhibit protein biosynthesis.
macrolideOne of a range of antibiotics with a wide spectrum of action that can be used as an alternative to the penicillins to treat respiratory infections including LEGIONNAIRES' DISEASE. The group includes erythromycin, azithromycin and clarithromycin.
as in antibiotic; any antibiotic with molecules having many-membered lactone rings, e.g. erythromycin, spiramycin, tylosin.
