Biological Description
Chemical Properties
Storage & Solubility Information
Description SAR-260301 is an orally available and selective inhibitor of PI3Kβ (IC50: 23 nM).
Targets&IC50 PI3Kγ:10000 nM, pAkt:49 nM, PI3Kα:1539 nM, DNA-PK:2000 nM, PI3Kβ:23 nM, PI3KC2γ:3812 nM, Vps34:183 nM, PI3Kδ:468 nM
In vitro SAR-260301 inhibits pAktS473 (a measured IC50: 0.06 μM and an estimated IC90: 2 μM), in the UACC-62 tumor cell line assay. SAR260301 inhibits PI3Kβ-dependent proliferation/viability in low serum conditions (IC50: 196 nM), in the MEF-3T3-myr-p110β mechanistic model. SAR260301 inhibits LNCaP cell proliferation in low and high serum conditions (IC50: 2.9 and 5.0 μM, respectively), after 4-day treatment, whereas it is inactive in these conditions in PC3 cells at concentrations up to 10 μM, despite target engagement). SAR260301 also leads to antitumor activities in PTEN-deficient/BRAF-mutant human melanoma cells, inhibiting cell proliferation (IC40: 6.5 and 3.3 μM for UACC-62 and WM-266.4, respectively, after 4-day treatment). After prolonged treatment, SAR260301 at 3 or 10 μM inhibits PC3 cell proliferation in low serum conditions, with a cytostatic effect achieved for 14 days, despite some cell death induction observed at 10 μM [2].
In vivo SAR-260301 is well tolerated at the active dose, with no sign of toxicity and no bodyweight loss. SAR-260301 displays antitumor efficacy in human PTEN-deficient melanoma models in mice as a single agent. SAR-260301 treatment leads to a statistically significant tumor growth inhibition as measured by a ΔT/ΔC of 39% (p = 0.054 versus control mice) on day 15 post-tumor implantation. SAR-260301(p.o.) reveals sustained target inhibition (≥50%) of pAkt-S473 for at least 7 h. SAR-260301 has moderate terminal elimination half-life (t1/2=0.87 h, 1.4 h, 2.5 h, 0.87h, 6.9 h and 4.5 h for female SCID mice (3 mg/kg, iv), mice (10 mg/kg, p.o.), mice (100 mg/kg, p.o.), female nude rats (3 mg/kg, iv), rat (10 mg/kg, p.o.), male beagle dogs (10 mg/kg, p.o.))

Molarity Calculator allows you to calculate the

  • Mass of a compound required to prepare a solution of known volume and concentration
  • Volume of solution required to dissolve a compound of known mass to a desired concentration
  • Concentration of a solution resulting from a known mass of compound in a specific volume
See Example

An example of a molarity calculation using the molarity calculator
What is the mass of compound required to make a 10 mM stock solution in 10 ml of water given that the molecular weight of the compound is 197.13 g/mol?
Enter 197.13 into the Molecular Weight (MW) box
Enter 10 into the Concentration box and select the correct unit (millimolar)
Enter 10 into the Volume box and select the correct unit (milliliter)
Press calculate
The answer of 19.713 mg appears in the Mass box

Calculate the dilution required to prepare a stock solution
The dilution calculator is a useful tool which allows you to calculate how to dilute a stock solution of known concentration. Enter C1, C2 & V2 to calculate V1.

See Example

An example of a dilution calculation using the Tocris dilution calculator
What volume of a given 10 mM stock solution is required to make 20ml of a 50 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=50 μM, V2=20 ml and V1 is the unknown:
Enter 10 into the Concentration (start) box and select the correct unit (millimolar)
Enter 50 into the Concentration (final) box and select the correct unit (micromolar)
Enter 20 into the Volume (final) box and select the correct unit (milliliter)
Press calculate
The answer of 100 microliter (0.1 ml) appears in the Volume (start) box
