HY-125118

GSK-A1 2 Publications Verification	PI4K HCV	Infection
GSK-A1 is a selective type III phosphatidylinositol 4-kinase PI4KA (PI4KIIIα) inhibitor with a pIC₅₀ of 8.5-9.8. GSK-A1 inhibits PtdIns(4,5)P2 resynthesis with an IC₅₀ of about 3 nM. GSK-A1 potently decreases the levels of PtdIns(4)P with a negligible effect on PtdIns(4,5)P2. GSK-A1 has the potential for anti-hepatitis C virus (HCV) research .

Phosphatidylinositol 4,5-bisphosphate L-alpha-Phosphatidylinositol-4,5-bisphosphate; (PtdIns)-(4,5)-P2	Phospholipase	Inflammation/Immunology
Phosphatidylinositol 4,5-bisphosphate (L-alpha-Phosphatidylinositol-4,5-bisphosphate) is a plasma membrane lipid that is enriched in the cytoplasmic leaflet of the plasma membrane. Phosphatidylinositol 4,5-bisphosphate serves as a substrate for phospholipase C and class I PI3K, generating diacylglycerol, inositol (1,4,5)-trisphosphate, and phosphatidylinositol (3,4,5)-trisphosphate. Phosphatidylinositol 4,5-bisphosphate contributes to lamellipodial protrusion, directional cell migration, focal adhesion lipid generation, and trafficking of the GABA_A receptor. Phosphatidylinositol 4,5-bisphosphate can be used in research related to acute lung injury and pulmonary edema .

PtdIns-(4,5)-P2-biotin trisodium	Drug Derivative PI3K	Others
PtdIns-(4,5)-P2-biotin trisodium is a Biotin-labeled PtdIns-(4,5)-P2 analog. PtdIns-(4,5)-P2-biotin trisodium is an affinity probe of PI3Kγ. PI3Kγ can catalyse the phosphorylation of PtdIns-(4,5)-P2 at the 3′-OH group, giving rise to the second messenger PtdIns(3,4,5)-P3 .

HY-179554

PtdIns-(4,5)-P2-fluorescein triethylammonium PI(4,5)P2-fluorescein triethylammonium	Fluorescent Dye	Others
PtdIns-(4,5)-P2-fluorescein (PI(4,5)P2-fluorescein) triethylammonium is a fluorescently labeled phosphatidylinositol-4,5-bisphosphate, which is a marked form of an important phospholipid signaling molecule (PIP2) on the cell membrane. PtdIns-(4,5)-P2-fluorescein triethylammonium can be used to detect proteins that interact with phosphatidylinositol-4,5-bisphosphate, such as PI3K, PTEN, and PH domain proteins, etc .
