dishevelled Activators

The chemical class of Dishevelled activators listed here primarily consists of compounds that modulate the Wnt/β-catenin signaling pathway. Dishevelled is a pivotal component of this pathway, transducing signals from Wnt ligands to downstream effectors. The activators are not specific to Dishevelled but influence its activity indirectly through the modulation of the Wnt signaling pathway. In the first category are GSK-3β inhibitors such as BIO, CHIR99021, and Lithium Chloride. GSK-3β is a key negative regulator of the Wnt/β-catenin pathway. Its inhibition leads to the stabilization of β-catenin, a downstream effector in the pathway. The stabilization of β-catenin indirectly enhances Dishevelled's function in transmitting the Wnt signal. SKL2001 and QS11 also function similarly by activating the Wnt/β-catenin signaling, thereby influencing Dishevelled activity.

The second category includes compounds like IWP-2 and LGK974, which modulate Wnt signaling upstream of Dishevelled. IWP-2 inhibits the production of Wnt ligands, while LGK974 inhibits PORCN, an enzyme involved in Wnt ligand maturation and secretion. These inhibitors can indirectly affect Dishevelled by altering the availability or activity of Wnt ligands. Lastly, compounds such as XAV939, IWR-1, FH535, and KY02111 modulate the Wnt pathway through various mechanisms. XAV939 and IWR-1 act by promoting β-catenin degradation or stabilizing Axin, a component of the β-catenin destruction complex, respectively. FH535 has a broader target range, including Wnt/β-catenin and PPAR signaling, while KY02111 promotes differentiation by inhibiting the Wnt pathway. It's important to note that the relationship between these chemicals and Dishevelled is based on their known effects on the Wnt signaling pathway. Direct interaction between these compounds and Dishevelled may not be established, and their effects on Dishevelled are inferred from their role in the Wnt/β-catenin pathway. Experimental validation is essential for confirming any potential interactions or effects on Dishevelled.
