Description

Application

3-Methyladenine (3-MA) is used to inhibit and study the mechanism of autophagy (lysosomal self-degradation) and apoptosis under various conditions. 3-MA inhibits autophagy by blocking autophagosome formation via the inhibition of type III Phosphatidylinositol 3-kinases (PI-3K). For use as an autophagy inhibitor, 3-MA is typically used at a concentration of 5 mM.

3-Methyladenine has been used as an autophagy inhibitor:

• to determine the expressions of autophagy-related genes (Beclin 1, light chain 3 (LC3) and p62) using the transfected human bone marrow mesenchymal stem cells (BM-MSCs)
• with cisplatin to study the inhibition of autophagy influenced cisplatin-induced apoptosis in A2780cp cells
• to study the interplay between colistin-induced autophagy and apoptosis

Standard for detection of nucleic acid methylation during carcinogenesis.

Preparation Note

This product is soluble in DMF (10 mg/mL; may require gentle heating). It is also soluble in water, 95% ethanol, or 1 N NaOH at 30 mg/mL with heating, but upon cooling, the product precipitates from solution. Solutions of 3-MA may be prepared in DMSO at 100 mM.
