Navitoclax has been used in trials studying the treatment and basic science of Solid Tumors, Non-Hodgkin's Lymphoma, EGFR Activating Mutation, Chronic Lymphoid Leukemia, and Hematological Malignancies, among others. Navitoclax is... Navitoclax is an orally bioavailable small molecule inhibitor of Bcl-2 family proteins.
- Mechanism
- Curator reviewed
Navitoclax targets the Bcl-2 family of proteins, the major negative regulators of apoptosis. The Bcl-2 proteins, including Bcl-2, Bcl-xL, and Bcl-w, work by binding to two other groups of proteins-the executioners (Bax, Bak) that actually start the destruction pathway, and the sentinel proteins. Cancer cells frequently overexpress the Bcl-2-like proteins, and thus, when they sustain DNA damage-from radiation, for example-they continue growing. Preventing the Bcl-2-like proteins from binding to the executioners might be able to trigger cell death in the tumor.
