Tyroserleutide hydrochloride
Based on 1 Customer Validation
Tyroserleutide hydrochloride is a tripeptide isolated from the degradation products of porcine spleen with antitumor activity. Tyroserleutide hydrochloride can upregulate the expression of the tumor suppressor gene PTEN and inhibit the activity of AKT and PDK1. Tyroserleutide hydrochloride inhibits tumor cell proliferation and MDM2 phosphorylation by inhibiting the PI3K/AKT pathway, and also upregulates P21, P27, P53, and induces mitochondrial damage and cell apoptosis.

Biological Activity
Tyroserleutide (YSL) exhibits immuno-modulating effects, such as enhancing concanavalin (ConA) induced proliferation of mouse spleen lymphocytes, phagocytosis of mouse peritoneal macrophages, and the activity of natural killer (NK) cells[1].
Tyroserleutide (YSL), an immunologically therapeutic tripeptide, can promote hepatocarcinoma cell (H22) apoptosis through downregulating Bcl-2 and cyclin D1 expression[2].
Tyroserleutide is an ideal choice for inducing apoptosis of liver tumor cells[2].
Tyroserleutide inhibits tumor growth and does not cause severe toxicities in the major organs. Tyroserleutide can inhibit tumor cell migration[2].

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: ≥ 2.08 mg/mL (4.98 mM); Clear solution
This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 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: ≥ 2.08 mg/mL (4.98 mM); Clear solution
This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 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.
