VPS34-IN2 is primarily utilized in research settings to study the role of the VPS34 enzyme in cellular processes. It is a potent inhibitor of VPS34, which is involved in autophagy and vesicular trafficking. By inhibiting VPS34, researchers can investigate its impact on cancer cell survival, immune responses, and neurodegenerative diseases. This compound is particularly valuable in understanding how autophagy modulation can influence tumor growth and resistance to therapies. Additionally, it aids in exploring potential therapeutic strategies for diseases where autophagy plays a critical role.
