CAL-130 is a novel, potent and selective PI3Kδ and PI3Kγ inhibitor with potential anticancer activity and with IC50s of 1.3 and 6.1 nM, respectively. Constitutive phosphoinositide 3-kinase (PI3K)/Akt activation is common in T cell acute lymphoblastic leukemia (T-ALL). Although four distinct class I PI3K isoforms (α, β, γ, δ) could participate in T-ALL pathogenesis, none has been implicated in this process. In the absence of PTEN phosphatase tumor suppressor function, PI3Kγ or PI3Kδ alone can support leukemogenesis, whereas inactivation of both isoforms suppressed tumor formation.

Biological Activity
| ln Vitro | The catalytic domains of p110γ and p110δ are preferentially inhibited by CAL-130; the IC50 values of CAL-130 for p110δ and p110η were 1.3 and 6.1 nM, respectively, while the IC50 values for p110α and p110β were 115 and 56 nM, respectively. Other intracellular signaling pathways, such as p38 MAPK or insulin receptor tyrosine kinase, that are essential for general cellular function and survival, are not inhibited by CAL-130 [1]. |
| ln Vivo | Interfering with the combined activities of PI3Kγ and PI3Kδ was found to have clinical significance when given to Lck/Ptenfl/fl mice that had T-cell acute lymphoblastic leukemia (T-ALL). The animals considered for survival studies are not well-groomed, their white blood cell (WBC) counts are higher than 45,000 μL-1, peripheral smears show blast activity, and most circulating cells (>75%) are Thy1.2 and Thy1-sensitive. 2 Positive staining twice. Base-67. Oral CAL-130 (10 mg/kg) was given to mice every 8 hours for 7 days, after which they were monitored until they became moribund. The median survival of treated animals was extended to 45 days by CAL-130, despite the short treatment duration, as opposed to 7.5 days for the control group [1]. |

Solubility Data
| Solubility (In Vitro) | May dissolve in DMSO (in most cases), if not, try other solvents such as H2O, Ethanol, or DMF with a minute amount of products to avoid loss of samples |
| Solubility (In Vivo) |
Note: Listed below are some common formulations that may be used to formulate products with low water solubility (e.g. < 1 mg/mL), you may test these formulations using a minute amount of products to avoid loss of samples. Injection Formulations (e.g. IP/IV/IM/SC) Injection Formulation 1: DMSO : Tween 80： Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution.
