Purity: ≥98%
Tenalisib (also known as RP6530) is a new, potent and selective dual PI3Kδ/γ inhibitor with anticancer activity. With IC50 values of 24.5 nM and 33.2 nM, respectively, it inhibits both PI3Kδ and PI3Kγ. With selectivity over the α and β isoforms of more than 300-fold and 100-fold, respectively, it exhibits selective for PI3Kδ/γ. Both HEL-RS and HEL-RR cells are moderately inhibited in terms of proliferation by tenalisib (33-46% inhibition at 10 μM). The combination of 10 μM tenalisib and ruxolitinib inhibits proliferation almost completely (>90% for HEL-RS and >70% for HEL-RR). The EC50 of ruxolitinib (5.8 M) in HEL-RR cells is significantly decreased when 5 M tenalisib is added 4 hours beforehand.

Tenalisib shows selectivity over PI3K α (>300-fold) and β (>100-fold) isoforms. In both HEL-RS and HEL-RR cells, tenalisib mildly inhibits proliferation (33-46% inhibition @ 10 μM). Inhibition of proliferation is nearly 100% (>90% for HEL-RS and >70% for HEL-RR) when 10 μM tenalisib is added to ruxolitinib. The EC50 of ruxolitinib (5.8 μM ) in HEL-RR cells is significantly decreased by the addition of 5 μM tenalisib 4 hours before the addition of ruxolitinib. When 10 μM tenalisib and ruxolitinib are combined for 72 hours, more cells undergo apoptosis (55% in HEL-RS and 37% in HEL-RR) than when either agent is used alone (16-27% in HEL-RS and 17-21% in HEL-RR)[1].

| ln Vivo |
Tenalisib has been well tolerated in subjects with heavily pre-treated relapsed/refractory hematologic malignancies. With no DLTs, reported toxicities are controllable. At less than 200 mg BID, single agent activity can be seen in patients who are challenging to treat[2].

| Cell Assay |
Potential of the combination (1 μM RP6530 + BORT between 0.1 nM and 1 μM) is studied in MM cell lines, namely, MM-1S and MM-1R. After incubating with the compound for 72 hours at 37°C, proliferation is assessed using a MTT assay. The combination's apoptotic potential is calculated using AnnexinV/PI staining.

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (6.02 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 25.0 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: ≥ 2.5 mg/mL (6.02 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 25.0 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: ≥ 2.5 mg/mL (6.02 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.
