Macrolide Antibiotics

The macrolides are a class of natural products that consist of a large macrocyclic lactone ring to which one or more deoxy sugars , usually cladinose and desosamine , may be attached. The lactone rings are usually , , or membered. Macrolides belong to the polyketide class of natural products. Some macrolides have antibiotic or antifungal activity and are used as pharmaceutical drugs. Macrolides are bacteriostatic in that they suppress or inhibit bacterial growth rather than killing bacteria completely. The first macrolide discovered was erythromycin , which was first used in Erythromycin was widely used as a substitute to penicillin in cases where patients were allergic to penicillin or had penicillin-resistant illnesses.

Macrolide Therapy in Chronic Inflammatory Diseases

Macrolides are a group of antibiotics with a distinctive macrocyclic lactone ring combined with sugars cladinose, desosamine. The action of macrolides is to block protein synthesis by binding to the subunit of 50S ribosome of bacteria. Prototype macrolide was erythromycin, which came into clinical practice in the 50s of the 20th century. Its antimicrobial spectrum covers the scope of the penicillins but is extended to the impact of atypical bacteria. In the 90s more drugs of this group were synthesized—they have less severe side effects than erythromycin, extended spectrum of Gram-negative bacteria. Macrolides are effective in treating mycobacterial infections especially in patients infected with HIV.

The current state of research, development, and use of macrolides as a treatment option for bacterial infections is the subject of this monograph. Macrolides, whose first representative erythromycin was introduced into the market in the s, have been optimised by various companies into effective, safe, and convenient treatments with overwhelming success. Various compounds, such as azithromycin, clarithromycin, erythromycin, and roxithromycin, are in current effective use for treatment of infections mainly of the respiratory, gastrointestinal, and urogenital tracts and skin and soft tissues.

John R. Lonks, Donald A. Goldmann, Louis D. Telithromycin, a recently approved ketolide antibiotic derived from membered macrolides, is active against erythromycin-resistant pneumococci. Telithromycin has enhanced activity in vitro because it binds not only to domain V of ribosomal RNA like macrolides do but also to domain II.

DOI: The advanced macrolides, azithromycin and clarithromycin, and the ketolide telithromycin are structural analogues of erythromycin. They have several distinct advantages when compared with erythromycin including enhanced spectrum of activity, more favorable pharmacokinetics and pharmacodynamics, once daily administration, and improved tolerability. This article reviews the pharmacokinetics, antimicrobial activity, clinical use, and adverse effects of these antimicrobial agents. View on PubMed.

Efforts to find macrolides that were active against macrolide-resistant strains led to the development of erythromycin analogs with alkyl-aryl side chains that mimicked the sugar side chain of membered macrolides, such as tylosin.
