|Description||Eganelisib (IPI-549) is a potent inhibitor of PI3K-γ with >100-fold selectivity over other lipid and protein kinases. The biochemical IC50 for PI3K-γ is 16 nM.|
IPI-549 is found to be a remarkably tight binder to PI3K-γ with a Kd of 290 pM and >58-fold weaker affinity for other Class I PI3K isoforms. It does not significantly inhibit a panel of 468 mutant and nonmutant protein and lipid kinases (including Class II PI3K isoforms) at 1 μM. In PI3K-α, -β, -γ, and -δ dependent cellular phospho-AKT assays, IPI-549 demonstrates excellent PI3K-γ potency (IC50 = 1.2 nM) and selectivity against other Class I PI3K isoforms (>146-fold). Furthermore, IPI-549 dose dependently inhibits PI3K-γ-dependent bone marrow-derived macrophage (BMDM) migration in vitro. IPI-549 is also found to be selective against a panel of 80 GPCRs, ion channels, and transporters at 10 μM. In vitro, IPI-549 shows moderate to high cell permeability across Caco-2 cell monolayers, is slowly metabolized in cultured hepatocytes (t1/2 > 360 min), and demonstrates IC50s greater than 20 μM for the CYP isoforms tested (1A2, 2B6, 2C8, 2C9, 2C19, 2D6, 3A4).
|In vivo||In vivo (mice, rats, dog, and monkeys), IPI-549 has excellent oral bioavailability, low clearance, and distributes into tissues with a mean volume of distribution of 1.2 L/kg. It has a favorable pharmacokinetic profile to allow potent and selective inhibition of PI3K-γ in vivo. IPI-549 can significantly reduce neutrophil migration in a dose-dependent manner in mouse model when administered orally at all of the tested doses. In addition, IPI-54 has been shown to inhibit tumor growth in murine syngeneic models through alteration of immune cells in the tumor microenvironment.|

1.Please make sure the liquid is clear before adding the next solvent.
2.Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
