The CXCR4 is involved in chemotaxis and serves as a coreceptor for T-tropic HIV-1 viral entry and in cancer metastasis. IT1t is a small, drug-like, isothiourea derivative. IT1t shows very potent and dose-dependent inhibition of the CXCL12/CXCR4 interaction with an IC50 of 2.1 nM. This calcium flux is also inhibited by IT1t with an IC50 of 23.1[1]. Strong electron density is observed for IT1t in the binding cavity of both subunits of the CXCR4 homodimer. In dimers of CXCR4 bound to IT1t, the monomers interact only at the extracellular side of helices V and VI, leaving at least a 4 gap between the intracellular regions, which is presumably filled by lipids. The IT1t compound and CVX15 peptide have both been characterized as competitive inhibitors of CXCL12, and many of the receptor-ligand contacts in the co-crystal structures presented are important for CXCL12 binding, including the acidic Asp187, Glu2887.39 and Asp972.63. The binding site of IT1t may point to the major anchor region for this domain[2].

Solvent & Solubility
H2O : 50 mg/mL (104.26 mM; Need ultrasonic)
DMSO : ≥ 30 mg/mL (62.56 mM; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
* "≥" means soluble, but saturation unknown.
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, 6 months; -20°C, 1 month (sealed storage, away from moisture). When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.
* Note: If you choose water as the stock solution, please dilute it to the working solution, then filter and sterilize it with a 0.22 μm filter before use.

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: ≥ 1.67 mg/mL (3.48 mM); Clear solution
This protocol yields a clear solution of ≥ 1.67 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (16.7 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: ≥ 1.67 mg/mL (3.48 mM); Clear solution
This protocol yields a clear solution of ≥ 1.67 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (16.7 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.
For the following dissolution methods, please prepare the working solution directly:
It is recommended to prepare fresh solutions and use them promptly within a short period of time.

Protocol
Jurkat cells are incubated with serial dilutions (0.001, 0.01, 0.1, 1, 10, 100, 1000 μM) of IT1t at room temperature for two hours. Cytotoxicity of IT1t is also evaluated at 37°C over a longer period of time in MT-4 cells and PHA-stimulated PBMCs (ten day incubation) because these cell types are used in anti-HIV activity assays which last up to ten days. Cytotoxicity is evaluated microscopically and viability is assessed using the a kit[1].
