ln Vitro |
In RAW264.7 and Raji cells, IHMT-PI3K-455 (1 μM, 2 hours) suppresses PI3Kγ/δ-mediated AKT phosphorylation [1]. M2 macrophages generated from THP-1 and BMDM cells have their polarization changed by IHMT-PI3K-455 (1 μM, 72 hours) [1].

ln Vivo |
In the MC38 tumor xenograft model, IHMT-PI3K-455 (40 mg/kg orally; once daily for 30 days) reduces tumor development [1]. By attracting and activating more CD8+ killer T cells, IHMT-PI3K-455 (40 mg/kg, oral; once daily for 30 days) suppresses the growth of tumors [1].

Cell Assay |
Cell Differentiation Assay[1]
Cell Types: Macrophages Tested Concentrations: 0.1, 1 μM Incubation Duration: 72 h Experimental Results: Increased the proinflammatory M1 macrophage phenotype in a dose-dependent manner, with a concomitant dose-dependent decrease of the anti-inflammatory M2 macrophage phenotype. Repolarized M2 phenotype toward M1 phenotype in THP-1 and BMDM macrophages. Western Blot Analysis[1] Cell Types: RAW264.7 cells; Raji cells Tested Concentrations: 0, 0.01, 0.03, 0.1, 0.3, 1 μM Incubation Duration: 2 h Experimental Results: Potently inhibited the PI3Kγ-mediated AKT473 phosphorylation in RAW264.7 cells (human C5a stimulation) with an IC50 value of 0.015 μM. Potently inhibited the PI3Kδ-mediated AKT473 phosphorylation in Raji cells (anti-IgM stimulation) with an IC50 value of 0.010 μM. |
Animal Protocol |
Animal/Disease Models: MC38 tumor model[1]
Doses: 10 mg/ kg, 40 mg/kg Route of Administration: po (oral gavage); one time/day for 30 days Experimental Results: Dramatically inhibited tumor size in a dose-dependent manner. Increased tumor-infiltrating CD8+T cells. |

Solubility (In Vivo) |
Note: Listed below are some common formulations that may be used to formulate products with low water solubility (e.g. < 1 mg/mL), you may test these formulations using a minute amount of products to avoid loss of samples.
Injection Formulations
Injection Formulation 1: DMSO : Tween 80: Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline)(e.g. IP/IV/IM/SC) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution. Injection Formulation 2: DMSO : PEG300 :Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL DMSO → 400 μLPEG300 → 50 μL Tween 80 → 450 μL Saline) Injection Formulation 3: DMSO : Corn oil = 10 : 90 (i.e. 100 μL DMSO → 900 μL Corn oil) Example: Take the Injection Formulation 3 (DMSO : Corn oil = 10 : 90) as an example, if 1 mL of 2.5 mg/mL working solution is to be prepared, you can take 100 μL 25 mg/mL DMSO stock solution and add to 900 μL corn oil, mix well to obtain a clear or suspension solution (2.5 mg/mL, ready for use in animals).

Injection Formulation 4: DMSO : 20% SBE-β-CD in saline = 10 : 90 [i.e. 100 μL DMSO → 900 μL (20% SBE-β-CD in saline)] Oral Formulations
Oral Formulation 1: Suspend in 0.5% CMC Na (carboxymethylcellulose sodium) Oral Formulation 2: Suspend in 0.5% Carboxymethyl cellulose Example: Take the Oral Formulation 1 (Suspend in 0.5% CMC Na) as an example, if 100 mL of 2.5 mg/mL working solution is to be prepared, you can first prepare 0.5% CMC Na solution by measuring 0.5 g CMC Na and dissolve it in 100 mL ddH2O to obtain a clear solution; then add 250 mg of the product to 100 mL 0.5% CMC Na solution, to make the suspension solution (2.5 mg/mL, ready for use in animals).

5 mM | 0.3865 mL | 1.9324 mL | 3.8648 mL | |
10 mM | 0.1932 mL | 0.9662 mL | 1.9324 mL |
*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
Calculation results
Working concentration: mg/mL;
Method for preparing DMSO stock solution: mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation::Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O,mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
