Umbralisib (tosylate)

Umbralisib (TGR-1202) tosylate is an orally active, potent and selective dual PI3Kδ and casein kinase-1-ε (CK1ε) inhibitor, with EC50 of 22.2 nM and 6.0 μM, respectively. Umbralisib tosylate exhibits unique immunomodulatory effects on chronic lymphocytic leukemia (CLL) T cells. Umbralisib tosylate can be used for haematological malignancies reseach[1][2][3][4].
