| ln Vitro |
In MM cells with elevated baseline p-Akt, Pifusertib hydrochloride (1 μM; 6 hours) inhibits downstream p-FKHR/FKHRL1 and basal phosphorylation of Akt [1]. In MM cells with high baseline phosphorylation of Akt, Pifusertib hydrochloride (0–10 μM; 72 hours) selectively inhibits Akt and causes cytotoxicity [1]. Pifusertib hydrochloride eliminates the myeloid microenvironment's cytoprotective effects in MM cells and BMSCs that are linked to Akt inhibition. In MM cells, carfilzomib-induced cytotoxicity and fatal ER stress are amplified by pflusertib hydrochloride. Pifusertib hydrochloride (0.5, 1 μM) stimulates autophagy and the endoplasmic reticulum stress response, which are linked to the generation of G0/G1 phase arrest and apoptosis [1]. Pifusertib increases the cytotoxicity induced by bortezomib, which is correlated with increases in the lethal endoplasmic reticulum stress marker CHOP, PARP cleavage, and blockade of p-Akt. These findings suggest that Pifusertib increases the cytotoxicity induced by bortezomib and apoptotic signaling [1].

| ln Vivo |
In a mouse xenograft model of human multiple myeloma, pifusertib hydrochloride (12–16 mg/kg; oral; once daily, 5 days per week for 21 days) suppresses tumor growth [1]. In vivo MM cytotoxicity mediated by bortezomib is enhanced by Pifusertib hydrochloride [1].

Cell Viability Assay[1]
Cell Types: MM cell lines Tested Concentrations: 0-10 μM Incubation Duration: 72 hrs (hours) Experimental Results: Induced significant growth inhibition in MM cell lines with high baseline p-Akt, but not in cell lines with low baseline p-Akt. Western Blot Analysis[1] Cell Types: MM.1S, MM.1R, H929, and KMS11 cells Tested Concentrations: 1 μM Incubation Duration: 6 hrs (hours) Experimental Results: Blocked basal phosphorylation of Akt and downstream p-FKHR/FKHRL1 in MM cells with high baseline p-Akt, but did not inhibit autophosphorylation of PDK1 which phosphorylates Akt at Thr308. |

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.08 mg/mL (4.51 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.8 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.08 mg/mL (4.51 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.8 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C，1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. View More
Solubility in Formulation 3: ≥ 2.08 mg/mL (4.51 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution. |

*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.
