Functions

IPI-549 is a potent and highly selective inhibitor of PI3K-γ in both biochemical (IC50 = 16 nM) and cellular (IC50 = 12.2 nM) assays. Macrophage PI3K-γ has been found to be a critical switch between immune stimulation and suppression.  IPI-549 has been used to reshape tumor immune microenvironments and promote cytotoxic T-cell-mediated tumor regression.  Resistance to immune checkpoint blockade in 4T1 and B16-GMCSF tumors was overcome when anti-PD-1 or anti-CTLA4 therapies were combined with PI3K-γ inhibition via IPI-549. IPI-549 mono-treatment also resulted in tumor growth inhibition in several cancer cell lines. IPI-549 has also been shown to modulate P-glycoprotein-mediated multidrug resistance.

 

Application Procedures

First dissolved in DMSO (up to at least 25 mg/ml), then diluted to aqueous buffer. Solutions in DMSO may be stored at -20°C for up to 1 month.
