Description Chloramphenicol,
 
also known as chlornitromycin, is a broad-spectrum, bacteriostatic antibiotic derived from Streptomyces venezuelae. It is first isolated from cultures of Streptomyces venequelae in 1947 but now produced synthetically. The synthetic product is racemic, also called synthomycin. Syntomycin is a mixture of chloramphenicol L-isomer and d-isomer. Because of dextroisomer antibacterial effect, the effect of synthomycin is only half of the natural products. It has a relatively simple structure and was the first broad-spectrum antibiotic to be discovered. It is effective against several gram-positive and gram-negative bacteria and commonly used in researching protein synthesis and to select for chloramphenicol-resistant transformed cells or the bacterial CAT gene.
Chloramphenicol is a semisynthetic, broad-spectrum antibiotic derived from Streptomyces venequelae with primarily bacteriostatic activity. Chloramphenicol diffuses through the bacterial cell wall and reversibly binds to the bacterial 50S ribosomal subunit. The binding interferes with peptidyl transferase activity, thereby prevents transfer of amino acids to the growing peptide chains and blocks peptide bond formation. As a result bacterial protein synthesis is blocked and impede bacterial cell proliferation.
Chemical Properties It is white or yellowish green needle like crystals. The melting point is 150.5-151.5℃ (149.7-150.7℃). Under the high vacuum it can be sublimated, slightly soluble in water (2.5mg/ml at 25℃), slightly soluble in propylene glycol (150.8mg/ml), soluble in methanol, ethanol, butanol, ethyl acetate, acetone, insoluble in ether, benzene, petroleum ether, vegetable oil. Taste is very bitter.
Uses
Chloramphenicol is used for the treatment caused by typhoid bacillus, dysentery bacillus, Escherichia coli, bacillus, influenza and pneumococcal infections such as brucellosis.
Chloramphenicol is used in the treatment of infections caused by bacteria. It works by killing bacteria or preventing their growth.
 
Antimicrobial Spectrum Chloramphenicol is bacteriostatic and a broad-spectrum antibiotic active against both gram-positive and gram-negative bacteria including rickettsia (cause of rocky-mountain spotted fever) and chlamydia. It is also found effective against Haemophilus influenzae causing meningitis.
Gram-positive: Streptococcus spp., Staphylococcus spp., Enterococcus spp., Bacillus anthracis, Listeria monocytogenes.
Gram-negative: Hemophilus influenzae, M. catarrhalis, N. meningitides, E. coli, P. mirabilis, Salmonella spp., Shigella spp., Stenotrophomonas maltophilia.
Mechanism of action Inhibition of protein synthesis, Chloramphenicol irreversibly binds to a receptor site on the 50S subunit of the bacterial ribosome, inhibiting peptidyl transferase. This inhibition consequently results to the prevention of amino acid transfer to growing peptide chains, ultimately leading to inhibition of protein formation.
