Clofazimine
Based on 13 publication(s) in Google Scholar
Clofazimine is an orally-active anti-mycobacterial agent with a wide range of anti-mycobacterial activity including leprosy and tuberculosis. Clofazimine exerts anti-inflammatory activities and anti-tumor activities by interfering DNA replication and inhibiting IL2 (IC50 = 1.10 ± 0.26 μM, Jurkat T) production. Clofazimine can be used in mycobacterial and cancer research.

Clofazimine (0.0625-2 mg/L, 14 d) exerts no apparent activity against M. tuberculosis during the first 2–4 days of exposure, exhibits a concentration-dependent antimicrobial activity after 1 week: bacteriostatic activity at concentrations at or below the 0.25 mg/L MIC and bactericidal activity at concentrations above the MIC. INH is used as positive control.[3].
Clofazimine (10 μM, 24 h) inhibits the growth of hematological cancer cell lines (Jurkat, U266, Namalwa, K562, HL60)[4].
Clofazimine (1-50 μM, 12-48 h) shows a dose- and time-dependent inhibitory effect for U266[4].
Clofazimine (10 μM, 24-48 h) depolarizes the mitochondrial membrane, significantly increases active caspase-3 level (25-fold) and increases the percentage of early and late apoptotic cells in U266[4].

-
Dosage:100, 50, 25, 12.5, 6.25, 3.125 or 1.5625 mg/kg
-
Administration:Oral gavage (p.o.), once per day for 14 d
-
Result:Exhibited an increase of the lung bacterial load during the first 7 days of treatment, and decreased the CFU counts in the lungs of mice after 10 days of treatment.
Significantly declined the lung CFU counts in 100 or 50 mg/ kg group at 14th day.
