PIK-90 also inhibits p110β, p110δ, PI3KC2α, PI3KC2β, hsVPS34, PI4KIIIα, PI4KIIIβ, ATR, ATM and mTORC1 with IC50s of 350 nM, 58 nM, 47 nM, 64 nM, 830 nM, 830 nM, 3.1 μM, 15 μM, 610 nM and 1.05 μM, respectively[1]. To determine the effects of PIK-90 on chronic lymphocytic leukemia (CLL) cell viability, CLL cells from different patients are incubated with various concentrations of PIK-90 (1 μM and 10 μM) for 24, 48, and 72 hours. PIK-90 reveals the strong apoptosis-inducing effects at both concentrations and at all different time points. Using a concentration of 10 μM, PIK-90 reduces the viability of CLL cells to 51.1% plus or minus 6.6% at 24 hours, whereas 1 μM PIK-90 reduces the viability to 77.8% plus or minus 6.4%[2].

Solvent & Solubility
1 M HCl : 100 mg/mL (284.61 mM; Need ultrasonic)
DMSO : 6.67 mg/mL (18.98 mM; ultrasonic and adjust pH to 2 with HCl; 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, 2 years; -20°C, 1 year. When stored at -80°C, please use it within 2 years. When stored at -20°C, please use it within 1 year.

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: ≥ 0.67 mg/mL (1.91 mM); Clear solution
This protocol yields a clear solution of ≥ 0.67 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (6.7 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: ≥ 0.67 mg/mL (1.91 mM); Clear solution
This protocol yields a clear solution of ≥ 0.67 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (6.7 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.
For the following dissolution methods, please prepare the working solution directly:
It is recommended to prepare fresh solutions and use them promptly within a short period of time.

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
To determine the viability of CLL B cells, 200 μL cells are removed from the wells of a 24-well plate at the indicated time points and incubated for 15 minutes in fluorescence-activated cell sorter buffer (RPMI+0.5% BSA) containing 40 nM 3,3′-dihexyloxacarbocyanine iodide (DiOC6) and 10 μg/mL Propidium iodide (PI). Within 30 minutes, the cells are then analyzed by flow cytometry. Viable cells show high DiOC6 and low PI fluorescence, whereas apoptotic cells have low DiOC6 and PI fluorescence; necrotic cells are characterized by low DiOC6 and high PI fluorescence. The normal PBMCs are also cultured under the same conditions, with or without the various PI3K inhibitors (e.g., PIK-90, 1 μM and 10 μM), Fludarabine, and with or without stromal cell support, and their viability is also determined by staining with DiOC6 and PI[2].

Mice[3]
Human primary GBM43 cells (106) are injected s.c. just caudal to the left forelimb in 4- to 6-wk-old female BALB/c nu/nu mice. After tumors are established (50-100 mm3), mice are randomly allocated to daily i.p. treatment with 40 mg/kg PIK-90 (DMSO:H2O), 50 mg/kg Roscovitine (DMSO:PBS), 40 mg/kg PIK-90 plus 50 mg/kg Roscovitine, and DMSO:H2O:PBS (control). Tumor diameters are measured with calipers at 3-d intervals, and volumes are calculated.
