Biological Activity

Description	Cetrimonium Bromide (CTAB) is a known component of the broad-spectrum antiseptic cetrimide, which is a mixture of different quaternary ammonium salts.

In vitro
In vitro	Cetrimonium Bromide reduces cell viability of FaDu, C666-1, UTSCC-8A, UTSCC-42A, MRC5 cells and GM05757 fibroblasts with EC50 of 2 μM, 3.8 μM, 3.5 μM, 4.2 μM, 11 μM and 18 μM, respectively. Cetrimonium Bromide reduces cell viability of A549 lung and MCF7 breast cancer cells with EC50 of 17 μM and 12 μM. Cetrimonium Bromide (0.5 μM) interacts additively with radiation in a dose-dependent manner to exhibits inhibition effect on the clonogenic survival of FaDu cells. Cetrimonium Bromide results in nuclear condensation and blebbing in FaDu cells, consistent with apoptotic nuclear morphology, which is not observed in CTAB-treated GM05757 fibroblasts. Cetrimonium Bromide reproducibly decreases ATPase activity in a dose-dependent manner in FaDu cells, achieving ∼90% inhibition at 50 μM. Cetrimonium Bromide (5 μM) causes a modest (∼10%), but statistically significant decreases in ATP content in FaDu cells. Cetrimonium Bromide (5 μM) induced apoptosis is significantly suppressed by >50% when CCCP (5 μM) is used to effectively uncouple ΔΨM before Cetrimonium Bromide treatment in FaDu cells. ^[1]

In Vivo
In vivo	Cetrimonium Bromide (5 μM) effectively eliminates the tumor-forming potential of FaDu cells in SCID mice. Cetrimonium Bromide (daily 5 mg/kg i.p. for 5 days) induces a modest reduction in tumor development compared with the vehicle-treatment arm in established FaDu xenograft tumors in SCID mice. ^[1]

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH₂O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
