740 Y-P

740 Y-P (740YPDGFR; PDGFR 740Y-P) is a potent and cell-permeable PI3K activator. 740 Y-P readily binds GST fusion proteins containing both the N- and C- terminal SH2 domains of p85 but fails to bind GST alone^[1]. IC50 & Target:PI3K^[1] In Vitro: 740 Y-P (50 μg/mL; 48 hours) specificly stimulates mitogenesis in medium is better than EGF or FGF at stimulating entry into S-phase, it shows the percentage of cells in S-phase for 48.3% in C2 cells. Additionally, LY294002 (HY-10108) or Wortmannin (HY-10197) potently inhibits the mitogenic response stimulated by the peptide^[1].
740 Y-P (1 μg/mL) stimulates mitogenesis at the lowest concentration tested. The peptide stimulates mitogenesis in both the presence and absence of serum (0.5%), and in the former instance a maximal response observed at 50 μg/mL. 740Y-P to stimulate mitogenesis is highly specific and not a general feature of a cell permeable SH2 domain binding peptides^[1].
740 Y-P (30 μM; 24 hours) remarkably inhibits the level of LC3-II/LC3-I in GO-induced PC12 cells^[2].
In Vivo: 740 Y-P is not only internalised in living cells but can also interact with p85 in vivo^[1].
740 Y-P (intraperitoneal?injection; 10 mg/kg; 6 weeks) decreases the degree of ROS levels in Aβ(25-32) treated hippocampal tissues and increases the extent of AKT and PI3K phosphorylation in alzheimer’s disease (AD) rat model^[3].
