IA-Alkyne
Based on 4 publication(s) in Google Scholar
IA-Alkyne (Iodoacetamide-alkyne; N-Hex-5-ynyl-2-iodo-acetamide) is a TRP channel (TRPC) agonist and has the potential for the study of respiratory infection. IA-Alkyne can be used to develop an isotopically tagged probe for quantitative cysteine-reactivity profiling. IA-Alkyne is a click chemistry reagent, it contains an Alkyne group and can undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) with molecules containing Azide groups.

Biological Activity
IC50: TRPC[1]
IA-alkyne (2.5-10 μM; 1 hour) can react with cysteines. Soluble fractions of HeLa cell lysates (2.0 mg/ml) are treated with IA-alkyne. Labeled proteome samples are conjugated with a fluorescent rhodamine-azide tag through CuAAC, and analyzed by SDS-PAGE. In-gel fluorescence imaging reveals that IA-alkyne has a strong fluorescent intensity[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Triptolide derivative STP1 ameliorates murine systemic lupus erythematosus via targeting Fyn kinase. [Abstract]2026 Feb 11. PMID: 41673457
IA-Alkyne purchased from MedChemExpress. Usage Cited in: Acta Pharmacol Sin. 2026 Feb 11. [Abstract]
Fyn was validated as a direct target of STP1 in splenocyte lysate by ABPP and Western blotting. The results showed that Fyn was obviously pulled down by the azido-iodoacetamide (IA-Alkyne, 10 μM; 1 h) probe, and the amount of Fyn was significantly reduced by STP1 competition.

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 (9.43 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
