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.

Description

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[1][2][3][4][5].

Quinolone

 

In Vitro

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). For U266, Clofazimine (1-50 μM, 12-48 h) shows a dose- and time-dependent inhibitory effect[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].

In Vivo

Clofazimine (100,50 mg/kg, p.o., once per day for 14 d) exhibits a delayed antimicrobial activity against Mycobacterium tuberculosis in mice[3].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: Female BALB/c mice (age 6–8 weeks, mass 18–20 g)[3]
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.

In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 0.62 mg/mL (1.31 mM); Clear solution

    This protocol yields a clear solution of ≥ 0.62 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (6.2 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

    Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
  • Protocol 2

    Add each solvent one by one:  10% DMSO    90% (20% SBE-β-CD in Saline)

    Solubility: 0.62 mg/mL (1.31 mM); Suspended solution; Need ultrasonic

    This protocol yields a suspended solution of 0.62 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (6.2 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

    Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
