PI3K inhibitors are a class of compounds that target the PI3K enzyme, which plays a critical role in cell growth, survival, and proliferation. Dysregulation of the PI3K pathway is commonly observed in various cancers and other diseases, making PI3K inhibitors promising candidates for therapeutic development. These inhibitors work by blocking the activity of PI3K, thereby inhibiting downstream signaling pathways that promote cell growth and survival. Several PI3K inhibitors have been developed and are currently being investigated in preclinical and clinical studies for their potential to treat a wide range of diseases, including cancer, autoimmune disorders, and inflammatory conditions.
