| Name | Seletalisib |
| Description | Seletalisib (UCB5857) (UCB5857) is a potent and specific PI3Kδ inhibitor (IC50: 12 nM). |
| Cell Research | Seletalisib is dissolved 1 mM solution in DMSO, and tested in a concentration-response, to explore the effects of PI3Kδ-specific inhibition compared with complete inhibition of class I PI3K signaling. In addition, seletalisib is tested in the BioMap BT cell system at concentrations of 1000, 100, 10, and 1 nM. An activity profile is generated based on the effect of the compounds on the levels of cellular readouts, including cytokines, growth factors, adhesion molecules, and proliferation endpoints. |
| Animal Research | Rats are dosed with Seletalisib (0.1-10 mg/kg in 500 μL volume) or vehicle via oral gavage 30 min prior to i.v. administration of anti- CD3 antibody administered in a 200 μL dose volume. The vehicle is methylcellulose or saline for oral and i.v. administration, respectively. Seletalisib levels and IL-2 levels are measured. |
| In vitro | Seletalisib is able to block AKT phosphorylation following activation of the BCR in a B-cell line. No indications of cytotoxicity are observed in PBMCs or other cell types treated with Seletalisib. Seletalisib blocks human T-cell production of several cytokines from activated T-cells. Seletalisib inhibits T-cell differentiation to Th1, Th2, and Th17 subtypes. Additionally, Seletalisib inhibits B-cell proliferation and cytokine release. In human whole blood assays, Seletalisib inhibits CD69 expression upon B-cell activation and anti-IgE-mediated basophil degranulation. |
| In vivo | Seletalisib markedly reduces IL-2 release in response to TCR stimulation in rats, achieving near-total suppression at doses ≥1 mg/kg. This compound demonstrates strong in vivo activity, with an estimated IC50 value of <10 nM across all tested concentrations. |
| Storage | Powder: -20°C for 3 years | In solvent: -80°C for 1 year | Shipping with blue ice. |
| Solubility Information | DMSO : 80 mg/mL (165.69 mM)
