Parsaclisib (INCB050465) is a potent, selective and orally active inhibitor of PI3Kδ, with an IC₅₀ of 1 nM at 1 mM ATP. Parsaclisib shows approximately 20000-fold selectivity over other PI3K class I isoforms. Parsaclisib can be used for the research of relapsed or refractory B-cell malignancies^[1][2][3].

Parsaclisib (0.1-3000 nM; 4 d) inhibits proliferation of MCL and DLBCL cell lines^[2].
Parsaclisib (0.1-1000 nM; 2 h) inhibits anti-IgM-induced pAKT (Ser473) in the Ramos Burkitt’s lymphoma cell line, with an IC₅₀ of 1 nM^[2].
Parsaclisib inhibits the proliferation of human, dog, rat, and mouse primary B cells after activation of these receptors, with IC₅₀s ranging from 0.2 to 1.7 nM^[2].

Parsaclisib (10 mg/kg; oral gavage twice daily for 7-19 days) inhibits tumor growth in the BALB/c mice bearing the A20 murine lymphoma cells^[2].
Parsaclisib (0.1-10 mg/kg; p.o. twice daily) slows Pfeiffer xenograft tumor growth in a dose-dependent manner. And Parsaclisib was well tolerated^[2].
Parsaclisib (0.5-1 mg/kg; a single p.o.) inhibits pAKT (Ser473) in Pfeiffer subcutaneous mouse xenograft models^[2].
