Chlorhexidine is a orally active cationic antimicrobial agent that targets microbial cell membranes. Chlorhexidine binds to cell membrane phospholipids non-specifically, destroys membrane structure and induces leakage of cell contents. Chlorhexidine has broad-spectrum bactericidal activity against both Gram-positive and Gram-negative bacteria. Chlorhexidine can interfere with membrane permeability, cause protein precipitation and energy metabolism disorders, such as rapid inhibition of microbial growth and induction of cell death (necrosis or apoptosis).

体外実験

1. Cell death assay:
Chlorhexidine (0.000125%-0.016%; 24 h) induces cell death in L929 fibroblasts, inducing a pattern of cell necrosis and/or apoptosis, as well as cell stress. Furthermore, Chlorhexidine induces apoptosis at lower concentrations and necrosis at higher concentrations, and increases the expression of heat shock protein 70 (a marker of cell stress). Chlorhexidine may have an adverse effect on the resolution of apical periodontitis^[1].
2. Cell viability experiment:
Chlorhexidine (0.0005%-0.5%; 30 min) causes the death of canine embryonic fibroblasts with concentration of ≥0.013%, while allows the cells to survive with concentration of ≤0.006%^[2].
3. Bacterial survival experiment:
Chlorhexidine (0.0005%-0.5%; 30 min) has a concentration-dependent bactericidal effect on Staphylococcus aureus, and kills Staphylococcus aureus with concentration of ≥0.05%, while allows the bacteria to survive with concentration of ≤0.03%^[2].

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

Cell Viability Assay^[3]

Cell Line:

Canine embryonic fibroblasts
Concentration:

0.5%, 0.05%, 0.03%, 0.013%, 0.006%, 0.005%, 0.0005%
Incubation Time:

30 min
Result:

Fibroblasts showed 0% survival at concentrations ≥0.013%, while concentrations ≤0.006% allowed significant survival (e.g., 74% survival at 0.0005%), indicating a concentration-dependent cytotoxic effect.

体内実験

1. Paw injection toxicity test:
Chlorhexidine (0.125%-1.0%; subcutaneous injection; single dose) causes toxic effects in the plantar space of the hind paw of Balb/c mice. Concentrations ≥0.5% induces coagulative necrosis of the epidermis, dermis and subcutaneous tissues and neutrophil-dominated inflammatory responses, while concentrations ≤0.25% induces moderate inflammation and interstitial edema^[1].
2. Lung inhalation toxicity test:
Chlorhexidine (0.125%-1%; intratracheal instillation; single dose; 8-week observation) causes collagen fiber deposition and inflammatory cell infiltration in lung tissue in the C57BL/6J mouse model, leading to restrictive ventilation dysfunction. Transcriptome analysis shows that genes related to extracellular matrix deposition and mucus secretion (such as Muc5b and Muc5ac) are upregulated^[3].
3. Genetic toxicity test:
Chlorhexidine (0.12% Chlorhexidine dihydrochloride, 0.5 mL; oral, twice a day for 8 days) causes DNA damage in peripheral blood and oral mucosal cells of rats, without causing chromosome breakage or loss in erythrocytes^[4].

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

Animal Model:

Male Balb/c mice (4 weeks old, 20 g), paw subplantar injection model^[1]
Dosage:

0.125%, 0.25%, 0.5%, 1.0% Chlorhexidine in distilled water
Administration:

Subplantar injection into the right hind paw, single dose, observed at 24 h, 48 h, 7 days, and 14 days
Result:

At 0.5% and 1.0%, caused extensive coagulative necrosis in the epidermis, dermis, and subcutaneous tissue, associated with marked neutrophilic inflammation and edema at 24-48 h; 0.25% induced focal necrosis in few specimens and moderate inflammation in all; 0.125% caused no necrosis but moderate neutrophilic inflammation and edema.
Epidermal healing was complete by 7-14 days, with residual mononuclear cell infiltration and fibrous tissue thickening in high-dose groups.

Animal Model:

C57BL/6J mice (6-8 weeks old), intratracheal instillation-induced lung injury model^[2]
Dosage:

0.125% (2.5 mg/kg), 0.25% (5 mg/kg), 0.5% (10 mg/kg), 1% (20 mg/kg) Chlorhexidine gluconate in RO water
Administration:

Single intratracheal instillation via MicroSprayer Aerosolizer, observed for 8 weeks
Result:

Led to dose-dependent lung tissue damage, including inflammatory cell infiltration, alveolar protein deposition, and airway epithelial cell exfoliation.
Increased collagen fiber deposition in the alveolar septum and bronchial stroma, with significantly higher lung organ coefficients in high-dose groups.
Decreased respiratory system compliance (Crs) and forced vital capacity (FVC), indicating restrictive ventilatory dysfunction.
Upregulated genes related to extracellular matrix organization (e.g., P4ha3) and mucus secretion (e.g., Muc5b, Muc5ac).

Stock Solution Working Solution

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.

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
