PIK-93

PIK-93 Chemische Eigenschaften,Einsatz,Produktion Methoden

• Beschreibung

  PIK-93 is an inhibitor of phosphatidylinositol 4-kinase IIIβ (PI4KIIIβ; IC₅₀ = 19 nM). It is selective for PI4KIIIβ over PI4KIIIα and PI4KIIα (IC₅₀s = 1,100 and >100,000 nM, respectively). However, it also inhibits the PI3K catalytic subunits (IC₅₀s = 39, 590, 120, and 16 nM for p110α, p110β, p110δ, and p110γ, respectively). PIK-93 reduces enteroviral RNA replication when used at a concentration of 125 nM in HeLa cells. It also inhibits the transport of ceramide from the endoplasmic reticulum to the Golgi apparatus.

• Verwenden

  PIK 93 is a PI3Kγ and PI4KIIIβ inhibitor.

• Enzyminhibitor

  This potent and selective PI3Kγ/PI4KIIIβ inhibitor (FW = 389.88; CAS 593960-11-3; Solubility (25°C): 78 mg/mL DMSO, <1 mg/mL Water), also known as N-[5-[4-chloro-3-[(2-hydroxyethyl)sulfamoyl]phenyl]-4- methylthiazol-2-yl]acetamide, impairs actin filament consolidation and stability at the leading edge in cells treated with N-formyl-Met-Leu-Phe as well as ceramide transport between ER and Golgi compartments. The inhibition of PI3K by PIK-93, LY294002, or wortmannin decreased carbachol-induced translocation of TRPC6 to the plasma membrane and carbachol-induced net Ca2+ entry into T6.11 cells. PIK-93 inhibits both poliovirus (PV) and hepatitis C virus (HCV) replication, with EC50 values of 0.14 μM and 1.9 μM, respectively. Targets: PI3Kγ, IC50 = 16 nM; PI4KIIIβ, IC50 = 19 nM; PI3Kα, IC50 = 39 nM; PI3Kδ, IC50 = 0.12 μM; and PI3Kβ, IC50 = 0.59 μM.
