740 Y-P (Synonyms: 740YPDGFR; PDGFR 740Y-P)

740 Y-P is an activator of PI3K with concentration of 20 μM [1].
PI3K (phosphoinositide 3-kinases, PI3Ks) is an enzyme and plays an important role in the fundamental cellular processes, such as vesicular trafficking, cell degranulation, cell migration, and glucose transporter. It has been reported that over-expression of PI3K was correlated with a variety kind of cancers [2].
740 Y-P is a potent PI3K activator and plays an important role in PI3K/AKT signaling pathway. When tested with human melanoma MNT-1 cells, 20 μM 740 Y-P for 24 hours treatment significantly reduced the number of M6PR-positive vacuoles induced by sucrose via activating PI3K [1]. In cerebellar granule cells in the circumstance of serum deprivation, 740 Y-P treatments reduced the cell death rate via binding to p85 which was correlated with PI 3-kinase-dependent phosphorylation of Akt process [3].
