Acalisib (GS-9820) is more selective for PI3Kδ (IC50=12.7 nM) relative to other PI3K class I enzymes (IC50: PI3Kα, 5,441 nM; PI3Kβ, 3,377 nM; PI3Kγ, 1,389 nM). Acalisib is also 103-fold more selective against PI3Kδ than against related kinases, such as PI3KCIIβ (IC50>10 nM), hVPS34 (IC50=12.7 μM), DNA-PK (IC50=18.7 μM), and mTOR (IC50>10 nM). In fibroblasts, the PDGF receptor signals through PI3Kα and the GPCR for lysophosphatidic acid (LPA) signals through PI3Kβ. Acalisib reduces PDGF-induced pAkt by only 50% at 11,585 nM, and LPA-induced pAkt by 50% at 2,069 nM.

Solvent & Solubility
DMSO : 125 mg/mL (311.41 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month (protect from light). When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (6.23 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (6.23 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.
Protocol
Biochemical in vitro lipid kinase assays are performed. A stock solution of Acalisib (GS-9820) is prepared in DMSO at a concentration of 10 mM. Ten-point kinase inhibitory activities are measured over a concentration range (5 to 104 nM) with ATP at a concentration consistent with the Km of each of the enzymes[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
The effect of inhibitors on RAW264.7 cell survival is evaluated using the MTT assay. RAW264.7 cells are seeded in Falcon flat bottom 96-well plates at a density of 2.5-3×104 cells/cm2 in 100 μL of DMEM with 10% FBS and 1% antibiotic solution. After seeding, the cells are allowed to attach for 24 h then exposed to control or Acalisib (GS-9820) (100 pM to 10 μM) for 24 h. After incubation at 37°C in 5% CO2, MTT substrate is added at a final concentration of 0.5 mg/mL for 4 h. Following a 4-h incubation, 100 μL of solubilization solution is added to each well to dissolve the formazan crystals and samples are analyzed after 24 h. Absorbance of the samples is assessed using a plate reader using a wavelength of 550 nm and a reference wavelength of 700 nm[1].

Mice[2]
Ob/ob C57BL6J mice and Wild-type C57BL6J/Ola.Hsd mice are housed under specific pathogen free (SPF) conditions, at 22°C, and with 12 hours dark/light cycles (light cycle from 8 am to 8 pm). All mice used are males of 20 weeks of age. Mice are fed with standard chow diet (18% of fat-based caloric content). PI3K inhibitors are administered daily by oral gavage during 15 or 16 days as follows, BYL-719 (5 and 10 mg/kg) and Acalisib (5 and 10 mg/kg), CNIO-PI3Ki (1 and 5 mg/kg), dissolved in PEG-300 and 10% N-methyl-2-pyrrolidone.
