Ligand Summary
Ligand Structure
Rendered image for the query structure
Umbralisib inhibits multiple kinases. In biochemical and cell-based assays, umbralisib inhibited PI3Kdelta and casein kinase CK1-epsilon. PI3K-delta is expressed in normal and malignant B-cells; CK1-epsilon has been implicated in the pathogenesis of cancer cells, including lymphoid malignancies. Umbralisib also inhibited a mutated form of ABL1 in biochemical assays. Umbralisib inhibited cell proliferation, CXCL12-mediated cell adhesion, and CCL19-mediated cell migration in lymphoma cell lines in studies conducted in vitro.
