Wnt agonist 1
Molecular Weight(MW): 386.83
Wnt agonist 1 is a cell permeable Wnt signaling pathway activator, which induces β-catenin- and TCF-dependent transcriptional activity with EC50 of 0.7 μM.

Both Wnt sinaling activators of agonist and recombinant protein, and therapeutic agents of fluorouracil and docetaxel stimulated TCF-4 promoter functions of wild-type (wt) could be blocked by Nano-Let-7b, compared with negative control group of mutant-type (mut). In detail, Let-7b alone affected the TCF-4 promoter activity effectively, and wnt signaling activators of either Wnt agonist-1 or Wnt protein attenuated the Let-7b functions significantly. Combined usage of therapeutic agent of either fluorouracil or docetaxel with Let-7b increased the TCF-4 activity when compared to groups treated with Let-7b alone, however, the TCF-4 activity when applying combination was still significantly lower than that of controlled group

Wnt agonist 1 does not inhibit the activity of GSK-3β, and may be a useful tool in the study of physiological processes that involve the Wnt pathway. Exposure human brain endothelial hCMEC/D3 cells to the Wnt agonist 1 led to an increase in the percentage of cells exhibiting nuclear or perinuclear β-catenin staining after exposure for 16 h to 10 μM (43 ± 2%, p < 0.01, n = 5) and 20 μM (48 ± 5%, p < 0.01, n = 5) compared with that of control (12 ± 1%, n = 5).
|In vivo||In a Xenopus model, Wnt agonist 1 (10 μM) mimics the effects of Wnt at the whole-organism level, and affects Xenopus embryonic head specification. In animal model (Rat renal IR model), Wnt agonist significantly lowered serum levels of creatinine, AST, and LDH, inhibited the production of IL-6 and IL-1β, and MPO activities. Wnt agonist reduced iNOS, nitrotyrosine proteins and 4-hydroxynonenal in the kidneys. Wnt agonist improves renal regeneration and function while attenuating inflammation and oxidative stress in the kidneys after IR.|

* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
