SQ109 also inhibits extracellular epimastigotes (IC50, 4.6±1 μM) and the clinically relevant intracellular amastigotes (IC50, ~0.5 to 1 μM), with a selectivity index of ~10 to 20. SQ109 has little effect (EC50, ~80 μM) in a red blood cell hemolysis assay. Besides, SQ109 causes major ultrastructural changes in all three life cycle forms, as observed by light microscopy, scanning electron microscopy (SEM), and transmission electron microscopy (TEM)[1].

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 (7.56 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.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (7.56 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
The LLC-MK2 cells are treated with SQ109 (2.5 to 20 μM) and incubated for 96 h at 37°C. Fresh RPMI 1640 medium containing only 10% FBS is added to the untreated samples as a control. To determine toxicity, the MTS/PMS assay is performed. The selectivity index of SQ109 is determined based on its activities against the trypomastigote and intracellular amastigote forms of T.cruzi, calculated as the ratio of the 50% cytotoxic concentration (CC50) of mammalian cells to the IC50 or 50% lysing concentration (LC50) of T.cruzi. All experiments are performed in duplicate. The means are determined from ≥3 experiments[1].

Mice[2]
Female C57BL/6 mice (8 weeks old) are used. Oral treatment of mice with INH (25 mg/kg), ethambutol (EMB) (100 mg/kg) and SQ109 (0.1, 10 and 25 mg/kg) is initiated 20 days after inoculation. Control groups of infected but untreated mice are killed at the initiation of therapy (early controls) or at the end of the treatment period. There are six mice per group. Chemotherapy is given daily for 5 days per week until the mice are killed, 4 weeks after initiation of treatment. The spleen and lungs are aseptically removed and weighed. The organs are homogenized in 2 ml of sterile PBS containing 0.05% Tween-80. Homogenate samples from individual tissues are diluted 10-fold in PBS and plated on 7H10 agar dishes. Inoculated dishes are incubated at 37°C in ambient air for 3 weeks prior to calculation of CFU. Viable counts are converted to a logarithmic scale; readings are corrected to represent whole organ totals. The severity of infection and the effectiveness of the treatments are assessed by the survival rate, and the mean number of CFU in mouse organs.
Rats and Dogs[3]
Male Fischer rats (271-289 g) and beagle dogs (7.5-8.9 kg, two males and two females per dose group) are used. Rats are given either a single intravenous (i.v.) bolus dose of 1.5 mg/kg (9 mg/m2) or an oral dose of 13 mg/kg (78 mg/m2) of SQ109 (n=8 per dose group); rats are divided into subgroups consisting of four rats per subgroup. Rat blood (0.7 mL) is withdrawn from the jugular vein catheter at alternating time points from individual rats in each subgroup. Blood samples are collected at 2, 5, 10, 15 and 30 min and 1, 3, 6, 10 and 24 h after a single i.v. administration, or 5, 15 and 30 min and 1, 2, 4, 6, 10 and 24 h after a single oral administration. Each blood sample is centrifuged to separate plasma, which is then stored at −70°C until analysis. Beagle dogs are dosed by gavage at either 3.75 or 15 mg/kg (75 or 300 mg/m2), or intravenously at either 0.45 or 4.5 mg/kg (9 and 90 mg/m2). Dog blood (0.7 mL) is withdrawn from the jugular vein at 2, 5, 10, 20 and 30 min and 1, 2, 4, 8, 12, 18 and 24 h after a single i.v. administration, or 10, 20 and 30 min and 1, 2, 4, 8, 12, 18 and 24 h after a single oral administration.
