Biological Activity
[Description]:
Umbralisib (TGR-1202) is a novel PI3Kδ inhibitor, with IC50 and EC50 of 22.2 nM and 24.3 nM, respectively; Umbralisib (TGR-1202) is also active against CK1ε, with an EC50 value of 6.0 μM.

PI3Kδ:22.2 nM (IC50)
[In Vitro]
Umbralisib (RP5264) causes a half-maximal inhibition of human whole blood CD19 cell proliferation between 100-300 nM[1]. In human lymphoma and leukemia cell lines, Umbralisib (RP5264; 10 nM-100 μM) inhibits phosphorylated AKT at Ser473 in a concentration-dependent manner. Umbralisib and carfilzomib synergistically kill blood cancer cells through disrupting the 4E-BP1-eIF4F-c-Myc axis. Umbralisib and carfilzomib in combination synergistically and selectively silence the c-Myc and E2F transcription programs. 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[2].
[In Vivo]
In a subcutaneous xenograft model of T-cell acute lymphoblastic leukemia (T-ALL) in NOD/SCID mice using the MOLT-4 cell line, Umbralisib (RP5264; 150 mg/kg, daily p.o.) significantly shrinks the tumors by day 25[2].
