It can be seen that the calcium channel blockers VIZ and Fantofarone (SR) possess a weak intrinsic antimalarial property compared to CQ, and both appear slightly more potent on the CQ-resistant than on the CQ-sensitive parasites. Interestingly, Fantofarone is ca. 10 times more potent than verapamil. Fantofarone (SR) is 10 times more potent than the phenylalkylamine verapamil (VR) on the two P. fdciparum strains. As revealed by the isobolograms, the two calcium channel blockers potentiate the CQ sensitivity activity on the CQ-resistant P. fufcipurum strain, verapamil appearing 2 to 3 times more potent than Fantofarone. Furthermore, when used at similar subinhibitory fractions of their IC50, VR is 2 to 3 times more potent than Fantofarone in decreasing CQ resistance[1].

Solvent & Solubility
DMSO : 100 mg/mL (181.58 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 2 years; -20°C, 1 year. When stored at -80°C, please use it within 2 years. When stored at -20°C, please use it within 1 year.

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: ≥ 2.5 mg/mL (4.54 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 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.

The co-solvents required include: DMSO, . All of co-solvents are available by MedChemExpress (MCE). , Tween 80. All of co-solvents are available by MedChemExpress (MCE).
Working solution concentration: 0.22 mg/mL
Method for preparing stock solution: mg drug dissolved in μL DMSO. Stock solution concentration: mg/mL.
1. Take μL DMSO stock solution;
2. Add μL .
μL , mix evenly;
3. Then add μL Tween 80, mix evenly;
4. Then add μL
Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.
Protocol
Rabbits[2]
Male White rabbits are used in this study (3.0-3.2 kg). All surgical procedures are performed under anaesthesia with a mixture of ketamine and xylazine. At the end of the experiments, the animals are sacrificed by a pentobarbital overdose. The proximal femoral arteries are exposed, and the isolated arterial segments are desiccated by air infusion delivered at a rate of 80 mL/min for 8 min. After desiccation is completed, the ligatures are released and flow is restored. At the day of surgery, a 2% cholesterol/6% peanut oil diet is started for 2 weeks. Before angioplasty, the animals are randomized in 4 groups of 10 animals:1. Placebo, 1 mL/kg of NaCl 0.9%, 2. Isosorbide dinitrate, 0.3 mg/kg, 3. Verapamil, 0.2 mg/kg, 4. Fantofarone, 50 mg/kg. The doses of isosorbide dinitrate, verapamil, and fantofarone are defined in a pilot experiment as the highest doses which did not show any hypotensive effect per se and are chosen very carefully according to their activity measured in other pharmacological models[2].
