Leniolisib

Research use only, not for human use.

A novel potent and selective PI3Kδ inhibitor with biochemical IC50 of 11 nM; displays >20-fold, 40-fold, and 200-fold selectivity over PI3Kα, PI3Kβ, and PI3Kγ, respectively.

A novel potent and selective PI3Kδ inhibitor with biochemical IC50 of 11 nM; displays >20-fold, 40-fold, and 200-fold selectivity over PI3Kα, PI3Kβ, and PI3Kγ, respectively; shows 30-fold cellular selectivity over PI3Kα; inhibits a large spectrum of immune cell functions, as demonstrated in B and T cells, neutrophils, monocytes, basophils, plasmocytoid dendritic cells, and mast cells in vitro; potently inhibits antigen-specific antibody production and reduces disease symptoms in a rat collagen-induced arthritis model.Other Indication Phase 2 Clinical(In Vitro):Expression of APDS mutant p110δ in cell lines and patient-derived lymphocytes lead to increased pathway activity, measured as phosphorylation of AKT or S6, which is suppressed by leniolisib in a concentration dependent way.(In Vivo):Oral leniolisib lead to a dose-dependent reduction in PI3K/AKT pathway activity and resolve the immune dysregulation with normalization of circulating transitional and na?ve B cells and reduction in PD-1+CD4+ and senescent CD57+CD8+ T cells. After 12 weeks of treatment, all patients show amelioration of lymphoproliferation with lymph node sizes and spleen volumes reduced by 39% (mean, range 26-57%) and 40% (mean, range: 13-65%), respectively.
