Description：Rifapentine (DL 473) is an antibiotic used in tuberculosis research.
In Vitro：Rifapentine shows antibacterial activity against clinical staphylococci, with MICs ranging from 0.002 to >10 μg/mL (MIC90 values of 1.28 μg/mL for MSSA and MSSE, and ≥10 μg/mL for MRSA and MRSE)[3].
In Vivo：Rifapentine (20 mg/kg, i.p., daily for five days followed by twice weekly for three weeks) reduces bacteria burden in the organs of a mouse model of disseminated Mycobacterium avium infection[2]. Rifapentine (a single dose of 30 mg/kg, i.v.) shows a plasma Cmax, T1/2 and AUC0-15 were 33 µg/mL (0.5 h), 4 h and 170 µg h/mL in rabbits. In lung tissue, the Cmax, T1/2 and AUC0-15 are 13 µg/mL (2 h), 6.7 h and 82 µg h/mL[4].
