Biological Activity

Description PI-3065 is a selective p110δ inhibitor with IC50 of 15 nM, >70-fold selectivity over other PI3K family members.

In vitro

PI-3065 shows no inhibition on the growth of 4T1 cells, which do not expressing detectable levels of p110δ. [1]

In vivo In mouse model, PI-3065 (75 mg/kg, p.o.) also suppresses 4T1 tumor growth and metastasis via inactivation of p110δ. In the LSL.KrasG12D/+; p53R172H/+; PdxCretg/+ (or KPC) model of pancreatic ductal adenocarcinoma, PI-3065 prolongs survival and reduces the incidence of macroscopic metastases and other disease-associated pathologies.

Cell Research:


- Collapse
  • Cell lines: 4T1 cells
  • Concentrations: ~10 μM
  • Incubation Time: 48 hours
  • Method:

    Proliferation of 4T1 cells is assayed following a 4-h treatment with the indicated p110δ inhibitors, then washing and MTS staining are carried out after 48 h culture.

Bio Calculators

Molarity Calculator

Molarity Calculator

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)

  • Mass
    Molecular Weight

*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and SDS / COA (available on product pages).

Dilution Calculator

Dilution Calculator

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 )

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.
