Triclosan is a broad-spectrum antibacterial agent that inhibits bacterial fatty acid synthesis at the enoyl-acyl carrier protein reductase (FabI) step. Triclosan inhibits E. coli enoyl-acyl carrier protein reductase (FabI) and FabI containing a glycine-to-valine substitution at position 93 (FabIG93V) with IC50s of 2 µM and 10 µM, respectively. Triclosan causes apoptotic effect in cultured rat neural stem cells (NSC). Triclosan exacerbates colitis and colitis-associated colorectal tumorigenesis in animal models.

Description

Triclosan is a broad-spectrum antibacterial agent that inhibits bacterial fatty acid synthesis at the enoyl-acyl carrier protein reductase (FabI) step. Triclosan inhibits E. coli enoyl-acyl carrier protein reductase (FabI) and FabI containing a glycine-to-valine substitution at position 93 (FabIG93V) with IC50s of 2 µM and 10 µM, respectively. Triclosan causes apoptotic effect in cultured rat neural stem cells (NSC). Triclosan exacerbates colitis and colitis-associated colorectal tumorigenesis in animal models[1][2][3].

In Vitro

Triclosan (1-100 μM ; 24 h) decreases in cell viability in dose and time dependent manners with 50 and 100 μM. Triclosan with 50 μM significantly increases cleaved caspase3 and Bax proteins and decreases Bcl-2[2].
Triclosan (50 μM ; 1-3 h) induces the increased expressions of both phosphorylated p38 and JNK proteins[2].
Triclosan (10-50 μM ; 3 h) with 50 μM decreases the GSH activity and increases the ROS generation to about 40% in cultured NSCs[2].

Cell Viability Assay[2]

Cell Line: Neural stem wells
Concentration: 1, 10, 20, 30, 50 and 100 μM
Incubation Time: 24 h
Result: Initiated the decreases in cell viability in dose and time dependent manners with 50 and 100 μM.

Western Blot Analysis[2]

Cell Line: Neural stem wells
Concentration: 50 μM
Incubation Time: 1, 3 h
Result: Did not affect the expressions of MAPK signaling proteins per se.
Differentially induced the increased expressions of both phosphorylated p38 and JNK proteins.
In Vivo

Triclosan (5, 50, 500 mg/kg; oral gavage, five days a week for a total of four weeks) causes an increase in the production of anti‐Der f IgE, IL‐4, and IL‐13[3].

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

Animal Model: Wild type BALB/cJ mice[3]
Dosage: 5, 50, 500 mg/kg
Administration: Oral gavage, five days a week for a total of four weeks
Result: Caused an increase in the production of anti- dermatophagoides farinae (Der f) IgE, IL‐4, and IL‐13, and this resulted in the aggravation of airway hyperresponsiveness in aeroallergen‐exposed wild type mice.

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    90% (20% SBE-β-CD in Saline)

    Solubility: ≥ 2.5 mg/mL (8.63 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 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.
  • Protocol 2

    Add each solvent one by one:  10% DMSO    90% Corn Oil

    Solubility: ≥ 2.5 mg/mL (8.63 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.

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.
