Parsaclisib hydrochloride (INCB050465 hydrochloride) is a potent, selective and orally active inhibitor of PI3Kδ, with an IC 50 of 1 nM at 1 mM ATP. Parsaclisib hydrochloride shows approximately 20000-fold selectivity over other PI3K class I isoforms. Parsaclisib hydrochloride can be used for the research of relapsed or refractory B-cell malignancies.

体外研究(In Vitro)
Parsaclisib (0.1-3000 nM; 4 d) inhibits proliferation of MCL and DLBCL cell lines.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.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. has not independently confirmed the accuracy of these methods. They are for reference only.
体内研究(In Vivo)
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.
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.
Parsaclisib (0.5-1 mg/kg; a single p.o.) inhibits pAKT (Ser473) in Pfeiffer subcutaneous mouse xenograft models. has not independently confirmed the accuracy of these methods. They are for reference only.
