Hazard Information | Back Directory | [Description]
IPI-549 (1693758-51-8) is a potent and highly selective inhibitor of PI3K-γ in both biochemical (IC50?= 16 nM) and cellular (IC50?= 12.2 nM) assays.1?Macrophage PI3K-γ has been found to be a critical switch between immune stimulation and suppression.2?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-549.3?IPI-549 mono-treatment also resulted in tumor growth inhibition in several cancer cell lines.3?IPI-549 has also been shown to modulate P-glycoprotein-mediated multidrug resistance.4 | [Uses]
IPI-549 is a selective phosphoinositide-3-kinase (PI3Kγ) Inhibitor. PI3Kγ inhibitors can be used to develop potential treatment for inflammatory and autoimmune diseases. | [in vivo]
Eganelisib (IPI549) demonstrates favorable pharmacokinetic properties and robust inhibition of PI3K-γ mediated neutrophil migration. In vivo (mice, rats, dog, and monkeys), Eganelisib has excellent oral bioavailability, low clearance, and distributed into tissues with a mean volume of distribution of 1.2 L/kg. Overall, Eganelisib has a favorable pharmacokinetic profile to allow potent and selective inhibition of PI3K-γ in vivo. The t1/2 of IPI-549 for mouse, rat, dog and monkey is 3.2, 4.4, 6.7 and 4.3 h, respectively. Eganelisib significantly reduces neutrophil migration in a dose dependent manner in this model when administered orally at all of the tested doses[1]. | [IC 50]
