Chloramphenicol synthesis
WebDec 15, 1976 · Several concentrations of chloramphenicol (ranging from 0.4 to 4.0 μg/ml) were used so that inhibition of protein synthesis ranged from 40 to 95%. Under these conditions, we examined the synthesis of RNA, ribosomal proteins and 50S ribosomal subunits as well as the synthesis of total protein. WebChloramphenicol is a synthetic antibiotic, which was first isolated from strains of Streptomyces venezuelae. It has a broad spectrum of activity against Gram-positive and Gram-negative bacteria. Chloramphenicol inhibits bacterial protein synthesis by blocking the peptidyl transferase step (elongation inhibition).
