SP-alkyne
Based on 1 Customer Validation
SP-alkyne is a T cell activation inhibitor probe that covalently binds to and labels Exportin-1 (XPO1) protein in cells. SP-alkyne is an alkyne derivative of SP-100030 (HY-110177). SP-alkyne potently inhibits T cell activation by covalently labeling cysteine residues of XPO1. SP-alkyne inhibits IL-2 production as well as AP-1 and NFAT reporter gene activity. SP-alkyne can be used for research on idiopathic pulmonary fibrosis.

In Vitro
SP-alkyne (1 μM; 1 h) covalently labels recombinant human XPO1 protein, and this labeling is blocked by pretreatment with Selinexor (HY-17536)[1].
SP-alkyne (1 μM; 1 h) specifically labels wild-type XPO1 in Jurkat cells expressing wild-type or mutant (C528S) XPO1, but fails to label the C528S mutant protein[1].

Animal Model:C57BL/6 (female, 8 weeks old)[1]
-
Dosage:10 mg/kg; 30 mg/kg
-
Administration:i.p.; once daily; 5 days
-
Result:In spleen lysates, XPO1 was labeled at 10 mg/kg and 30 mg/kg, with stronger labeling at 30 mg/kg.
In lung lysates, XPO1 was also labeled at 10 mg/kg and 30 mg/kg.
Target engagement with XPO1 in the lung and spleen was dose-dependent.

Solvent & Solubility
In Vitro:
DMSO : ≥ 100 mg/mL (254.02 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. When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

In Vivo:
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 (6.35 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 (6.35 mM); Suspended solution; Need ultrasonic
This protocol yields a suspended solution of 2.5 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.
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.

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.
