Umbralisib hydrochloride causes a half-maximal inhibition of human whole blood CD19 cell proliferation between 100-300 nM.
Umbralisib hydrochloride (10 nM-100 μM) inhibits phosphorylated AKT at Ser473 in a concentration-dependent manner in human lymphoma and leukemia cell lines.
Umbralisib hydrochloride (15-50 μM) potently represses the expression of c-Myc in the DLBCL cell line LY7, and is uniquely characterized with structural features suitable for targeting CK1ε in lymphoma cells. has not independently confirmed the accuracy of these methods. They are for reference only.

Umbralisib hydrochloride (150 mg/kg, daily p.o.) significantly shrinks the tumors by day 25 in a subcutaneous xenograft model of T-cell acute lymphoblastic leukemia (T-ALL) in NOD/SCID mice using the MOLT-4 cell line. has not independently confirmed the accuracy of these methods. They are for reference only.
