With the exception of Candida parapsilosis and Candida krusei, all isolates tested under planktonic conditions showed MIC values of ≤1.5 μg/mL. Alexidine dihydrochloride exhibits activity against most Candida spp. Fascinatingly, clinically significant fluconazole-resistant Candida isolates such as C. albicans (CA2, CA6, and CA10), C. glabrata (CG2 and CG5), C. parapsilosis (CP5), and C. auris (CAU-09 and CAU-03) are all significantly active against alexidine dihydrochloride[1].
When Alexidine dihydrochloride is used to inhibit planktonic growth, it completely stops the fungi being imaged from filamentating or proliferating. Alexidine dihydrochloride is able to decimate at low concentrations (1.5 to 6 μg/mL) mature biofilms of Candida, Cryptococcus, and Aspergillus spp. that are known to be resistant to almost all classes of antifungal drugs. In reality, alexidine dihydrochloride could prevent lateral yeast formation and biofilm dispersal in Candida albicans at concentrations of planktonic MICs that are 10-fold lower—150 ng/mL—than those of Candida albicans[1]. HUVECs and lung epithelial cells are 50% killed by alexidine dihydrochloride at concentrations five to ten times higher than the minimum inhibitory concentration needed to kill planktonically growing fungal pathogens[1]. |

decided to concentrate on C. albicans biofilm formation because this fungus has a well-established murine biofilm model that is used to evaluate the efficacy of both new and old antifungal medications. When the drugs are seen under a microscope, the impact they have on the 24-hour-old biofilms that are developing in the mice's jugular vein catheters is evident. The biofilm density in the catheters treated with Alexidine dihydrochloride is considerably lower. In fact, compared to the untreated control biofilms, alexidine dihydrochloride inhibits 67% of the growth and viability of fungal biofilms, according to fungal CFU determination[1].

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.08 mg/mL (3.58 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.8 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.08 mg/mL (3.58 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.8 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C，1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. View More
Solubility in Formulation 3: ≥ 2.08 mg/mL (3.58 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution. Solubility in Formulation 4: 10% DMSO+40% PEG300+5% Tween-80+45% Saline: ≥ 2.08 mg/mL (3.58 mM) |

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
Calculation results
Working concentration： mg/mL；
Method for preparing DMSO stock solution： mg drug pre-dissolved in μL DMSO (stock solution 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 stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O，mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
