Tubeimoside II

(別名: Tubeimoside-B)

カスタマーレビュー

Based on 1 Customer Validation

Tubeimoside II is an orally active triterpenoid saponin and antiviral agent that binds to PACT/PRKRA with K_d values of 5.37 μM and 133.1 μM, respectively. Tubeimoside II inhibits oxidase-dependent EGFR activation and reduces TGF-β1-induced oxidative stress. Tubeimoside II activates the RIG-I signaling pathway and increases IFN-β secretion. Tubeimoside II suppresses TPA-induced ear edema, mouse sarcoma 180 growth, and TPA-induced skin tumor formation. Tubeimoside II exerts broad-spectrum antiviral activity against SARS-CoV-2, HCoV-OC43, and IAV-H1N1/FM1. Tubeimoside II can be used in research related to retinoblastoma, respiratory viral infections, skin tumors, and sarcoma 180.

Tubeimoside II (1-5 μM; 12 h) inhibits TGF-β1-induced phosphorylation, oxidation and nuclear translocation of EGFR in retinoblastoma Y-79 and WERI-Rb-1 cells, while co-treatment with H₂O₂ or the EGFR activator NSC228155 reverses this effect^[1].
Tubeimoside II (0.25-1 μmol/L) exerts broad-spectrum antiviral activity against SARS-CoV-2, HCoV-OC43 and IAV-H1N1/FM1 in Caco-2-N, RAW264.7, A549 and Calu-3 cells, reduces viral load and alleviates cytopathic effects in a dose-dependent manner^[2].
Tubeimoside II exhibits broad-spectrum antiviral activity in A549 cells infected with IAV-H1N1/FM1, and this activity depends on the functional RIG-I signaling pathway, as knockout of RIG-I, MAVS or IFN-β abolishes its ability to reduce viral load and upregulate IFN-β expression^[2].

Stock Solution Working Solution

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.

Protocol 3

Add each solvent one by one: 10% DMSO 90% Corn Oil

Solubility: ≥ 2.5 mg/mL (1.87 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
