PI 3-kinase C2α Inhibitors

The chemical class of PI 3-kinase C2α inhibitors comprises a diverse array of compounds designed to modulate the activity of PI 3-kinase C2α, a crucial kinase involved in various cellular processes. Wortmannin, a direct inhibitor, covalently modifies the kinase's active site, impeding its ability to phosphorylate phosphatidylinositol substrates. LY294002 competes with ATP for binding to the kinase, disrupting its catalytic activity and affecting downstream signaling pathways. PI-103, a dual PI 3-kinase and mTOR inhibitor, provides a comprehensive approach to inhibit PI 3-kinase C2α and downstream signaling. AS252424, a potent and selective inhibitor, binds to the ATP-binding site of the kinase, suppressing its activity and offering a valuable tool for understanding the specific functions of PI 3-kinase C2α. IC87114, primarily a PI 3-kinase δ inhibitor, exhibits inhibitory effects on PI 3-kinase C2α, influencing cellular processes.

Compounds like YM201636, TGX-221, CAL-101, and GDC-0941 specifically target PI 3-kinase C2α, disrupting its kinase activity and downstream signaling cascades. ZSTK474, a broad-spectrum PI 3-kinase inhibitor, affects multiple isoforms, including PI 3-kinase C2α, providing a tool to study its functions comprehensively. BYL719, while selective for PI 3-kinase α, exhibits some inhibitory effects on PI 3-kinase C2α, influencing downstream signaling pathways. Additionally, 3-Methyladenine (3-MA) indirectly modulates PI 3-kinase C2α by inhibiting autophagy, a process regulated by this isoform. This indirect modulation offers insights into the interconnected roles of PI 3-kinase C2α in cellular processes beyond its direct catalytic activity. In summary, these PI 3-kinase C2α inhibitors provide a powerful toolkit for researchers to dissect the specific functions of this kinase in various cellular contexts. By targeting its catalytic activity or influencing related cellular processes, these compounds contribute to our understanding of PI 3-kinase C2α's roles and potential implications in diseases where dysregulation of this isoform is implicated.
