Description: NSC-92828, also known as 3-Phenanthrenebutyric acid, is a Protein–protein interaction inhibitor (2P2 inhibitor or 2P2I). Protein–protein recognition is the cornerstone of multiple cellular and pathological functions. Therefore, protein–protein interaction inhibition (2P2I) is endowed with great therapeutic potential despite the initial belief that 2P2I was refractory to small-molecule intervention.
