Umbralisib (TGR-1202) is an orally active, potent and selective dualPI3Kδand casein kinase-1-ε (CK1ε) inhibitor, withEC₅₀of 22.2 nM and 6.0 μM, respectively. Umbralisib exhibits unique immunomodulatory effects on chronic lymphocytic leukemia (CLL) T cells. Umbralisib can be used for haematological malignancies reseach^[1][2][3][4].

Umbralisib causes a half-maximal inhibition of human whole blood CD19 cell proliferation between 100-300 nM^[3].
Umbralisib (10 nM-100 μM) inhibits phosphorylated AKT at Ser473 in a concentration-dependent manner in human lymphoma and leukemia cell lines^[4].
Umbralisib (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^[4].

Umbralisib (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^[4].
