General description

Clarithromycin is a macrolide antibiotic, which has both antibacterial and anti-inflammatory actions. It is a semi-synthetic 14-membered derivative of erythromycin A, which is resistant to degradation under acidic conditions.

Application

Clarithromycin may be used for-
  • the study of the effects of clarithromycin on rate-dependent changes in QT, Tp-e and proarrhythmic events performed on arterially perfused rabbit left ventricular wedge preparations
  • the culture of parasites expressing GFP (green fluorescence protein) targeted to the apicoplast, to be further used for microscopy-based assays
  • the study of the synergism of NAB741 with clarithromycin in microtiter plates.

Biochem/physiol Actions

Macrolides, such as clarithromycin, prevent protein synthesis in bacteria, by binding to 50S ribosomal subunit. It also binds to other ribosomal proteins, and prevents the translocation of pepti-dyl-tRNA. In patients with refractory asthma, it is capable of regulating the levels of interleukin-8 (IL-8), and neutrophil accumulation and activation in lungs. Thus, it might be used as an additional therapy in asthma to reduce noneosinophilic airway inflammation.

Patients with refractory asthma have persistent symptoms despite maximal treatment with inhaled corticosteroids and long-acting bronchodilators. The availability of add-on therapies is limited, and effective add-on therapies that target noneosinophilic airway inflammation are needed. Macrolide antibiotics, such as clarithromycin, have

Drug-induced torsades de pointes (TdP) often occurs during bradycardia due to reverse use-dependence. We tested the hypothesis that inhibition or enhancement of late sodium current (I(Na,L) ) could modulate the drug-induced reverse use-dependence in QT and T(p-e) (an index of

Malarial parasites have evolved resistance to all previously used therapies, and recent evidence suggests emerging resistance to the first-line artemisinins. To identify antimalarials with novel mechanisms of action, we have developed a high-throughput screen targeting the apicoplast organelle of Plasmodium

After the discovery of erythromycin and other natural compounds, including oleandomycin, spiramycin, josamycin and midecamycin, much research has been devoted to synthesizing derivatives or analogues with improved chemical, biological and pharmacokinetic properties. These new macrolides are semisynthetic molecules that differ
