General description

Chemical structure: phenicole

Application

Thiamphenicol is an antibiotic that has been used to treat chancroid in men and uncomplicated gonorrhea. It is used in studies of bacterial protein synthesis at the level of peptidyl transferase activity associated with the 23S rRNA of the 50S ribosomal subunit. It is used to study chloraniphenicol-thiamphenicol-resistance and the use of fluorinated analogs when resistance is encountered.

Biochem/physiol Actions

Thiamphenicol inhibits mitochondrial protein synthesis of proteins such as cytochrome c oxidase.

Thiamphenicol was used to treat 547 men with chancroid. An oral dose of 2.5g was given on the first day and a further dose of 1.25g a week later if the lesions had not healed. Eighty-seven (15.9%) patients defaulted from
