CAL-101 (Idelalisib) PI3Kδ inhibitor

Cat.No.S2226

Idelalisib (CAL-101) is a selective p110δ inhibitor with IC50 of 2.5 nM in cell-free assays; shown to have 40- to 300-fold greater selectivity for p110δ than p110α/β/γ, and 400- to 4000-fold more selectivity to p110δ than C2β, hVPS34, DNA-PK and mTOR. Idelalisib also stimulates autophagy.

Mechanism of Action

Information	CAL-101 (Idelalisib) is a potent, selective PI3Kδ inhibitor. It affects the PI3K/AKT/mTOR signaling pathway by binding to the kinase ATP-binding cleft and reducing AKT phosphorylation, effectively inhibiting tumor cell proliferation and promoting apoptosis in hematological malignancies.

Frequently Asked Questions

Question 1:
What is the recommended dose and the route of administration for it in mouse studies?

Answer:
According to the following paper, it can be used by I.V. administration at the concentration of 40 mg/kg. https://www.ncbi.nlm.nih.gov/pubmed/24625684

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 )

*When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).
