| | PIK-93 Usage And Synthesis |
| Description | PIK-93 is the first potent, synthetic PI4K (PI4KIIIβ) inhibitor with IC50 of 19 nM; shown to inhibit PI3Kα with IC50 of 39 nM. | | Features | A novel and potent inhibitor of both PI3Kγ and PI4KIIIβ. | | In vitro | PIK-93 inhibits PI3Kγ and PI4KIIIβ, with IC50 values of 16 nM and 19 nM, respectively. PIK-93 also inhibits other members of PI3Ks, including PI3Kα, β, and δ, with IC50 values of 39 nM, 0.59 μM, and 0.12 μM, respectively. PIK-93 shows no obvious inhibitory effect against a panel of other kinases, even at a concentration of 10 μM. In differentiated HL60 (dHL60) cells, PIK-93 (0.5 μM–1 μM) impairs consolidation and stability of the leading edge formed after treatment with uniform f-Met-Leu-Phe (fMLP). PIK-93 alters the localization, but not the amount, of the fMLP-dependent accumulation of total F-actin. In fMLP gradients, PIK-93 reduces the chemotactic index and triples the cells' turning frequency. In COS-7 cells, PIK-93 (250 nM) effectively abrogates the accumulation of CERT-PH domain and FL-Cer in Golgi. PIK-93 of the same concentration also significantly inhibits the conversion of [3H]serine-labeled endogenous ceramide to sphingomyelin. These facts indicate a key role of PI4KIIIβ in ceramide transport between the ER and Golgi, as well as in the regulation of spingomyelin synthesis. In T6.11 cells, PIK-93 (300 nM) reduces carbachol-induced translocation of TRPC6 to the plasma membrane and net Ca2+ entry. A recent report shows that PIK-93 has anti-enterovirus effects, as revealed by its inhibition of both poliovirus (PV) and hepatitis C virus (HCV) replication, with EC50 values of 0.14 µM and 1.9 µM, respectively. | | Description | 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. | | Uses | PIK 93 is a PI3Kγ and PI4KIIIβ inhibitor. | | Enzyme inhibitor | 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. | | target | PI3Kγ | | references | [1] monet m, francoeur n, boulay g. involvement of phosphoinositide 3-kinase and pten protein in mechanism of activation of trpc6 protein in vascular smooth muscle cells. j biol chem. 2012 may 18;287(21):17672-81.
