CAL-101 Usage And Synthesis

DescriptionIdelalisib (CAS 870281-82-6) is a potent (IC50 = 2.5nM) and selective (IC50’s: PI3Ka = 820nM, PI3Kb = 565nM, PI3Kg = 89nM) PI3Kd inhibitor.1,2 Useful clinical agent for the treatment of various blood cancers. Idelalisib attenuates regulatory T cells (Treg) but not conventional T cells (Tconv) resulting in a significant increase in tumor-infiltrating antigen-specific CD8 T cells in a murine lung cancer model.3 Conversely, systemic PI3Kd inactivation antagonized anti-CTLA-4 and anti-PD-L1 treatment.4 Others have found that Idelalisib minimally influenced rituximab- and obinutuzumab-mediated Ab-dependent cellular cytotoxicity in human lymphoma cells.5
UsesCAL-101 is a PI3K/mTOR pathway inhibitor used in the treatment of myeloid leukemia through sensitizing the cells to combatting drugs. Potent PI3K-p110-delta inhibitor.
DefinitionChEBI: A member of the class of quinazolines that is 5-fluoro-3-phenylquinazolin-4-one in which the hydrogen at position 2 is replaced by a (1S)-1-(3H-purin-6-ylamino)propyl group. used for for the treatment of refractory indolnt non-Hodgkin's lymphoma and relapsed chronic lymphocytic leukemia.
in vitroCAL-101 (Idelalisib) is a highly selective and potent p110δ inhibitor (EC50=8 nM). Greater selectivity (400- to 4000-fold) is seen against related kinases C2β, hVPS34, DNA-PK, and mTOR, whereas no activity is observed against a panel of 402 diverse kinases at 10 μM. CAL-101 reduces PDGF-induced pAkt by only 25% at 10 μM. Idelalisib (CAL-101) inhibits LPA-induced pAkt with an EC50 of 1.9 μM. Idelalisib (CAL-101) blocks Fc?RI p110δ-mediated CD63 expression with an EC50 of 8 nM, whereas formyl-methionyl-leucyl-phenylalanine activation of p110γ is inhibited with an EC50 of 3 μM. Thus, CAL-101 has 240- to 2500-fold selectivity in cell-based assays for p110δ over the other class I PI3K isoforms. CAL-101Idelalisib (CAL-101)-induced apoptosis of chronic lymphocytic leukemia (CLL) cells is significant compared with vehicle treatment alone (P<0.001). Idelalisib (CAL-101) induces selective cytotoxicity in CLL cells independent of IgVH mutational status or interphase cytogenetics.
in vivoA significant reduction is observed in the CD11b+Ly6G+ neutrophils from brain homogenates of bothp110δD910A/D910A mice and Idelalisib (CAL-101) (40 mg/kg, i.v.) post-treated mice.
