Bromamphenicol(cas 16803-75-1) is a semi-synthetic chloramphenicol analogue first reported in 1950, in which the dichloroacetamide is
replaced with dibromoacetamide. Bromamphenicol possesses weak antibiotic activity. Comparative crystallography with
chloramphenicol helped defined the SARs of the acetamide binding region on the ribosome. More recently, this relationship
was used to demonstrate that chloramphenicol binding to DraE virulence factors in Gram negative bacteria was independent of
chloramphenicol binding site on the ribosome.
