2. Macrolides are a group of antibiotics
produced by various strains of
Streptomyces (spore-forming bacteria
that grow slowly in soil or water as a
branching filamentous mycelium similar
to that of fungi) and have a complex
chemical (macrocyclic) structure.
Macrolides act by inhibiting protein
synthesis, specifically by blocking the
50S ribosomal subunit. They are
broad-spectrum antibiotics. Azithromyci,
Clarithromycin, and Erythromycin are
drugs that belong to the Macrolides
class.

3. Clarithromycin, a semi-synthetic antibiotic belongs to the group of macrolide antibiotic. It
is used to treat infections caused by bacteria. It also acts as a novel chiral selector for
the enantiomeric separation of basic drugs in capillary electrophoresis.
Clarithromycin is metabolized to eight metabolites in the human body, but only one, the
14-hydroxy metabolite, has been shown to have antibacterial activity.
High-performance liquid chromatography is used to identify and estimate the
manufacturing and degradation impurities of Clarithromycin.
