PI5P4KG INHIBITOR NIH-12848 (C005B-229503)

General description

A cell-permeable quinazolinamine based compound that acts as a highly selective, non-ATP-competitive, and reversible inhibitor of phosphatidylinositol-5-phosphate-4-kinase γ (PI5P4Kγ; apparent IC₅₀ ~ 3.3 µM), but does not inhibit the activity of PI5P4Kα and PI5P4Kβ even at higher concentration (~100 µM). Suggested to bind at the PI5P binding region, including the activation loop. Also shown to be effective against E378H, I159V, and D161V mutant forms of PI5P4Kγ (71% inhibition at 10 µM). However, N165I mutant enzyme is resistant to its action even at higher concentration (~50 µM). Blocks the translocation of Na⁺/K⁺-ATPase to the plasma membrane in confluent mouse principal kidney cortical collecting duct (mpkCCD) cells in culture and prevents dome formation.
