Chemical Structure

Biological activities

PIK-93 is the first potent, synthetic Phosphoinositide kinases (PIK) inhibitor. PIK-93 shows to inhibit PI3Kα, PI3Kβ, PI3Kδ and PI3Kγ with IC50s of 39 nM, 0.59 µM, 0.12 µM and 16 nM, respectively.[1] PIK-93 inhibits carbachol-induced translocation of TRPC6,which is a cation channel in the plasma membrane and plays a role in Ca2+ entry after the stimulation of a G(q)-protein-coupled or tyrosine-kinase receptor,to the plasma membrane and carbachol-induced net Ca2+ entry into T6.11 cells. In vitro, PIK-93 at 0.5-1 µM impairs stability of the leading edge induced by uniform f-Met-Leu-Phe (fMLP) and alters the localization of the fMLP-dependent accumulation of F-actin in differentiated HL60 (dHL60) cells.[2] In T6.11 cells, PIK-93 at 300 nM blocks carbachol- induced translocation of TRPC6 to the plasma membrane.[3]

Protocols

In vitro, PIK-93 is dissolved in DMSO.[3]
