|Description||Duvelisib (IPI-145, INK1197) is a novel and selective PI3K δ/γ inhibitor with Ki and IC50 of 23 pM/243 pM and 1 nM/50 nM in cell-free assays, highly selective for PI3K δ/γ than other protein kinases. Phase 3.|
IPI-145 suppresses murine/human B-cell proliferation with EC50 of 0.5 nM/0.5 nM and also inhibits human T-cell proliferation with EC50 of 9.5 nM. 
|In vivo||IPI-145 (10 mg/kg, p.o.) shows well pharmacokinetics with Cmax and AUC of 390 ng/mL and 137 ng•h/mL in mouse and rat. IPI-145 (10 mg/kg) is active in murine DTH model with ~50% ear swelling. IPI-145 (10 mg/kg) demonstrates dose-dependent effect in rat collagen induced arthritis (CIA) model. IPI-145 prevents inflammation and protects joint bone and cartilage in the rat CIA model. IPI-145 (10 mg/kg,QD) demonstrates activity in rat adjuvant induced polyarthritis model. |

* 1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (g) = Concentration (mol/L) × Volume (L) × 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.
