Description

General description

Chemical structure: macrolide

Application

Rifapentine is an antibiotic clinically used to treat tuberculosis. It is used in tuberculosis research.

Biochem/physiol Actions

Rifapentine is a semisynthetic derivative of rifampicin with antibacterial activity against Gram-positive and Gram-negative bacteria and against Mycobacterium tuberculosis. Rifapentine inhibits DNA-dependant RNA polymerase and prevents RNA transcription. It interacts with bacterial RNA polymerase but does not inhibit the mammalian enzyme.
