😃Good
Catalog No. T212311

PI3Kδ-IN-25 is an orally active and selective PI3Kδ inhibitor with an IC50 of 2.1 nM. It exhibits IC50 values of 272, 285, and 1171 nM for PI3Kα, PI3Kγ, and PI3Kβ, respectively. In B16F10 cells, PI3Kδ-IN-25 inhibits the phosphorylation of AKTSer473, suppresses Treg cell proliferation, and downregulates the expression of PD-L1. In mouse models of B16F10 melanoma and Lewis lung cancer, PI3Kδ-IN-25 demonstrates anticancer activity by reducing tumor-infiltrating Treg cells and enhancing immune responses. This compound is applicable for research on cancers such as melanoma and lung cancer.

In vitro
PI3Kδ-IN-25 (Compound 18) at 1 μM effectively inhibits PIK3CD (93.37%), PIK3CG (87.63%), and PIK3CA (107.38%), while showing moderate activity against RIPK2 (58.65%) and PIK3CB (42.68%). After a 96-hour exposure, PI3Kδ-IN-25 demonstrates anti-proliferative effects on Ramos, DOHH2, Hela, BxPC3, SGC7901, BGC823, MX-1, A375, and B16F10 cells with IC50 values of 18.11, 14.39, 29.51, 22.13, 15.81, 13.06, 25.43, 21.95, and 11.42 μM respectively, while exhibiting weaker activity on K562, HepG2, and MCF-7 cells with IC50 values greater than 50 μM. Additionally, PI3Kδ-IN-25 (1-10 μM, 5-30 minutes) inhibits AKT Ser473 phosphorylation, indicating blockage of the PI3K signaling pathway in B16F10 cells. At concentrations of 1-10 μM over 72 hours, PI3Kδ-IN-25 reduces the proportion of CD4/CD25/FOXP3+++ as well as IL-10 concentration in mIL-2 and hTGFβ-induced Treg cells; at 10 μM, it downregulates PD-L1 expression in B16F10 cells.
In vivo
PI3Kδ-IN-25 (Compound 18) administered orally at doses of 1-30 mg/kg twice daily, suppresses tumor growth by modulating the tumor microenvironment in both B16F10 and Lewis xenograft mouse models.

In Vivo Formulation Calculator (Clear solution)

Please enter your animal experiment information in the following box and click Calculate to obtain the stock solution preparation method and in vivo formula preparation method:
TargetMol | Animal experiments For example, if the intended dosage is 10 mg/kg for animals weighing 20 g , with a dosing volume of 100 μL per animal, TargetMol | Animal experiments and a total of 10 animals are to be administered, using a formulation of TargetMol | reagent 10% DMSO+ 40% PEG300+ 5% Tween 80+ 45% Saline/PBS/ddH2O , the resulting working solution concentration would be 2 mg/mL.
Stock Solution Preparation:

Dissolve 2 mg of the compound in 100 μL DMSOTargetMol | reagent to obtain a stock solution at a concentration of 20 mg/mL . If the required concentration exceeds the compound's known solubility, please contact us for technical support before proceeding.

Preparation of the In Vivo Formulation:

1) Add 100 μL of the DMSOTargetMol | reagent stock solution to 400 μL PEG300TargetMol | reagent and mix thoroughly until the solution becomes clear.

2) Add 50 μL Tween 80 and mix well until fully clarified.

3) Add 450 μL Saline,PBS or ddH2OTargetMol | reagent and mix thoroughly until a homogeneous solution is obtained.
