Descrição

Descrição geral

Chemical structure: macrolide

Aplicação

Clarithromycin is a semisynthetic macrolide antibiotic that is derived from erythromycin. Clarithromycin may be bacteriostatic or bactericidal depending on the organism and drug concentration . Clarithromycin may be used to attenuate cardiac transplantation rejection via matrix metalloproteinase suppression. Clarithromycin has been used to study inflammatory markers in chronic obstructive pulmonary disease (COPD). It is used to study bacterial protein synthesis and peptide translation.

Ações bioquímicas/fisiológicas

Clarithromycin inhibits bacterial protein synthesis by binding to the bacterial 50S ribosomal subunit. Binding inhibits peptidyl transferase activity and interferes with amino acid translocation. Clarithromycin is first metabolized to 14-OH clarithromycin, which is active and works synergistically with its parent compound. Clarithromycin penetrates the bacteria cell wall and reversibly binds to domain V of the 23S ribosomal RNA of the 50S subunit of the bacterial ribosome, blocking translocation of aminoacyl transfer-RNA and polypeptide synthesis. Clarithromycin also inhibits the hepatic microsomal CYP3A4 isoenzyme and P-glycoprotein, an energy-dependent drug efflux pump.

Clarithromycin is a macrolide antibiotic that interferes with bacterial protein synthesis. Clarithromycin is an acid-stable version of erythromycin and is particularly effective against Gram-negative bacteria. It has a short half-life, however its metabolite, 14-hydroxy clarithromycin is nearly twice as active as clarithromycin against certain bacteria.

Nota de preparo

Practically insoluble in water, soluble in acetone and methylene chloride, slightly soluble in methanol.
