Nature nurtures the design of new semi-synthetic macrolide antibiotics
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. This review article focused not only on the their antimicrobial abilities but also on efficacy in the treatment of several inflammatory disorders independent of the infectious agent.
Author s : Luiz E. DOI : New macrolides, such as clarithromycin and azithromycin, are active agents to Mycobacterium avium complex MAC. Both clarithromycin and azithromycin are well-known for the ability to improve the prognosis of AIDS patients with disseminated MAC infection. However, the administration of monotherapy with a macrolide is usually associated with the emergence of drug resistance after a few months of use. When used as prophylactic therapy in AIDS patients, azithromycin is more convenient mg, once a week than clarithromycin mg, twice a day.
Macrolide Therapy in Chronic Inflammatory Diseases
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. However, it is not active against streptococci and staphylococci with constitutive macrolide, lincosamide, and streptogramin B resistance. Telithromycin, available in an oral formulation, is approved by the US Food and Drug Administration for use in adults for treatment of 1 community-acquired pneumonia due to Streptococcus pneumoniae including multidrug-resistant isolates , Haemophilus influenzae, Moraxella catarrhalis, Chlamydia pneumoniae , or Mycoplasma pneumoniae ; 2 acute exacerbation of chronic bronchitis due to S.

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 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. A highly competitive research environment and critical medical need for improved macrolides have led to various new scaffolds and derivatives such as the ketolides ABT and telithromycin, which are in development or in the regulatory process for market approval. The individual chapters cover aspects of microbiology, clinical use and experience, pharmacokinetics, pharmacodynamics, biochemistry, and chemistry. They are written by leading experts in their respective fields. Thus, readers - whether they are professionals in the pharmaceutical industry, physicians treating infections, or biochemists, chemists, pharmacologists or microbiologists at hospitals, health institutes, or universities - will find a detailed and up-to-date knowledge base about current research activities and a sound, stimulating overview of the compound class.

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.
