Which antibiotic binds to 50S ribosomal subunit?
Chloramphenicol. Chloramphenicol is a bacteriostatic agent that binds to the 50S ribosomal subunit. The drug has limited activity against the Enterobacteriaceae but remains effective against Salmonella/Shigella spp., including S.
What inhibits protein synthesis by combining with the 50S subunit ribosome?
Clindamycin inhibits protein synthesis by binding to the 50S bacterial ribosomal subunit and interfering with aminoacyl translocation reactions. It is active against streptococci, staphylococci, pneumococci, bacteroides species, and other anaerobes.
What are the different inhibitors of protein synthesis?
Antibiotics that inhibit or interferes with bacterial protein synthesis include; Aminoglycosides, Macrolides, Tetracycline, Oxazolidinone, and Chloramphenicol.
Which of the following ribosome inhibiting drugs are designed to bind to the 50S bacterial ribosomal subunit and inhibit peptide bond formation?
Chloramphenicol
Chloramphenicol. Chloramphenicol selectively inhibits protein synthesis in bacterial cells by binding to the 50S ribosomal subunit in the region of the A site involving the 23S ribosomal RNA.
Which antibiotics target bacterial ribosomes?
The majority of known compounds target the elongation cycle, including all of the clinically important antibiotic classes: the aminoglycosides, chloramphenicols, fusidic acids, lincosamides, macrolides, oxazolidinones, streptogramins and tetracyclines2.
What antibiotic is effective to treat bacterial pneumonia and works by inhibiting 50S ribosome?
Clindamycin is a lincosamide antibiotic which targets the 50S ribosomal subunit, inhibiting protein synthesis, and is bacteriostatic at typical treatment doses.
What are broad spectrum drugs?
A broad-spectrum antibiotic is an antibiotic that acts on the two major bacterial groups, Gram-positive and Gram-negative, or any antibiotic that acts against a wide range of disease-causing bacteria.
Why do antibiotics target ribosomes?
The ribosome is a major bacterial target for antibiotics. Drugs inhibit ribosome function either by interfering in messenger RNA translation or by blocking the formation of peptide bonds at the peptidyl transferase centre. These effects are the consequence of the binding of drugs to the ribosomal subunits.
Is gentamicin a penicillin?
Tetracyclines (e.g. doxycycline), quinolones (e.g. ciprofloxacin), macrolides (e.g. clarithromycin), aminoglycosides (e.g. gentamicin) and glycopeptides (e.g. vancomycin) are all unrelated to penicillins and are safe to use in the penicillin allergic patient.
