Definition

A phosphatidylinositol 3-kinase (PI3K) inhibitor with potential antineoplastic activity. PI3K inhibitor WX-037 specifically inhibits PI3K, which prevents the activation of the PI3K/protein kinase B-mediated signaling pathway. This may result in the inhibition of both tumor cell growth and survival in PI3K-overexpressing tumor cells. Activation of the PI3K signaling pathway is frequently associated with tumorigenesis. Dysregulated PI3K signaling may contribute to tumor resistance to a variety of antineoplastic agents.
