PI3K inhibitor

A PI3K inhibitor is a type of medication that blocks a specific enzyme called PI3K, which is involved in cell growth, survival, and division. In some cancers, the PI3K pathway becomes overactive, helping cancer cells grow and resist treatment. By inhibiting this enzyme, the drug aims to slow or stop tumor growth, making it a targeted approach in cancer therapy. PI3K inhibitors are used to treat certain types of cancers, such as breast and blood cancers, by disrupting the signals that cancer cells rely on to thrive.
