Biological Activity
Voxvoganan trihydrochloride (LTX-109) is an investigational antimicrobial agent with a membrane-lysing mechanism of action, based on the biological principle of innate immune effectors, lytic peptides. Voxvoganan trihydrochloride has a rapid bactericidal lytic activity. Voxvoganan trihydrochloride demonstrates in vitro bactericidal activity against a number of S. aureus isolates resistant to several classes of antimicrobial agents evaluated in this study[2].
Voxvoganan trihydrochloride (LTX-109) is a broad-spectrum, fast-acting bactericidal antimicrobial agent that binds to negatively charged membrane components on the bacterial cell wall, which leads to membrane disruption and cell lysis. Voxvoganan trihydrochloride is a first-in-class chemically synthesized, small peptide drug that is stable against protease degradation. Topical application of Voxvoganan trihydrochloride has a good safety profile and a low bioavailability. Voxvoganan trihydrochloride demonstrates good activity against Staphylococcus aureus strains that are susceptible and resistant to mupirocin[3].

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.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 3.5 mg/mL (3.90 mM); Clear solution
This protocol yields a clear solution of ≥ 3.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (35.0 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.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 3.5 mg/mL (3.90 mM); Clear solution
This protocol yields a clear solution of ≥ 3.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (35.0 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.
