Description: CTA056 is a potent and selective ITK inhibitor (interleukin-2-inducible T-cell kinase inhibitor). ITK is a member of the Btk (Bruton's tyrosine kinase) family of tyrosine kinases, plays an important role in normal T-cell functions and in the pathophysiology of both autoimmune diseases and T-cell malignancies. CTA056 exhibits the highest inhibitory effects toward Itk, followed by Btk and endothelial and epithelial tyrosine kinase. Among the 41 cancer cell lines analyzed, CTA056 selectively targets acute lymphoblastic T-cell leukemia and cutaneous T-cell lymphoma. CTA056 may be potential therapeutic agent for the treatment of T-cell leukemia and lymphoma.
