Application

2-Aminopurine (2-AP) is used to specifically inhibit double-stranded RNA-dependent protein kinase, protein kinase R (PKR).
2-Aminopurine has been used to inhibit eukaryotic initiation factor-2α (eIF2α)-phosphorylation of osteoarthritis (OA) chondrocytes.

Biochem/physiol Actions

2-Aminopurine (2AP) is an analog of guanosine and adenosine, which can base pair with cytosine and thymine. It is used as a fluorescent probe in nucleic acid structure and dynamics. 2-Aminopurine (2-AP) inhibits double-stranded RNA-dependent protein kinase, protein kinase R (PKR).
