A cell permeable, ATP-competitive and selective tolyl quinazolinone inhibitor of PI 3-Kδ (IC₅₀ = 7 nM, 1300 nM, 85000 nM, and 740 nM for PI 3-Kδ PI 3-Kγ PI 3-Kα and PI 3-Kβ, respectively) in an enzymatic assay with an EC₅₀ = 16 nM for PI 3-Kδ and 2.7 µM for PI 3-Kγ in a cell based assay. It elicits an inflammatory marker suppression effect in co-cultures of HUVEC and PBMCs under superantigen stimulated conditions. This compound, at concentrations between 370 nM and 10 µM, leads to a dose-dependent decrease in E-selectin expression. Furthermore, it is not cytotoxic to HUVEC cells.，官网链接：https://www.sigmaaldrich.cn/product/mm/526559 默克 科研、开发、生产。 作为生命科学行业的全球领先供应商，我们致力于为科研、生物技术开发和生产，以及制药药物疗法开发和生产提供各类解决方案和服务。
