Beschreibung

General description

A cell-permeable thiazolidinedione compound that acts as a potent and ATP-competitive inhibitor of PI 3-Kγ (K_i = 180 nM; IC₅₀ = 250 nM). Exhibits great selectivity over PI 3-Kα (IC₅₀ = 4.5 µM), PI 3-Kβ and δ (IC₅₀ >20 µM), and shows little effect towards a large panel of receptors, unrelated enzymes, ion channels, and 38 commonly studied kinases. Shown to block MCP-1-mediated monocyte chemotaxis in vitro and exhibit better in vivo efficacy than LY294002 (Cat. No. 440202 and 440204) in blocking RANTES- or thioglycollate-induced peritoneal neutrophil recruitment by oral administration in a murine peritonitis model.
