cadherin-7 Inhibitors

Cadherin-7 inhibitors encompass a chemical class of compounds that indirectly influence the function of cadherin-7 by modulating various cellular pathways and processes. These compounds typically do not interact directly with cadherin-7, but instead, they alter the cellular environment or signaling cascades that cadherin-7 depends on, ultimately leading to a decrease in its functional activity. For instance, calcium chelators like EGTA disrupt calcium-dependent cadherin adhesion by binding extracellular calcium which is essential for cadherin-7 function, leading to the loss of cadherin-mediated cell-cell adhesion.

Some compounds target specific signaling pathways involved in the regulation of cadherin expression and localization, such as XAV-939, which inhibits the Wnt pathway, known to be crucial for the regulation of gene expression including cadherins. Others, like GSK-3β inhibitors, affect the interaction between cadherins and catenins, which is vital for the stability of cell-cell adhesion. Inhibitors of kinases such as MEK, Src family kinases, and p38 MAPK can alter phosphorylation states of proteins that interact with cadherin-7, thereby modifying its adhesive functions. These compounds often have a broad range of effects due to the interconnected nature of cellular signaling pathways. Moreover, agents that affect the cytoskeleton, such as Rho kinase inhibitors, can perturb cadherin-mediated cell adhesion by altering the actin cytoskeleton and cell morphology. MMP inhibitors prevent the proteolytic cleavage of cadherin extracellular domains, thereby preserving the integrity of cadherin-mediated adhesion.
