3-Methyladenine
3-Methyladenine is an inhibitor of class III phosphoinositide 3-kinase (PI3K) [1].
3-Methyladenine is widely used as an autophagy inhibitor through inhibiting class III PI3K without significantly affecting protein synthesis or ATP levels. 3-Methyladenine also inhibits class I PI3K. It is found that 3-Methyladenine has different effects on class I and class III PI3K. It blocks class I PI3K persistently while inhibits class III PI3K transiently. As an inhibitor of autophagy, 3-Methyladenine is usually used to study the role of autophagy. In addition, 3-Methyladenine is also found to have anti-cancer efficacy. It induces cell death of tumor under nutrient-starved conditions. In HT1080 cells, 3-Methyladenine significantly inhibits cell migration through reducing membrane ruffle and lamellipodia formation in normal culture condition. It also inhibits the invasion of HT1080 cells [1, 2].
