R788, which is the prodrug of R406, is a potnet and selective Syk inhibitor. The spleen tyrosine kinase (Syk) plays a key role in the signaling of activating Fc receptors and the B-cell receptor (BCR).
In vitro: R406 was found to induce the apoptosis of the majority of examined DLBCL cell lines and could specifically inhibit both tonic- and ligand-induced BCR signaling (autophosphorylation of SYK525/526 and SYKdependent phosphorylation of the B-cell linker protein [BLNK]) [1].
In vivo: R788 effectively inhibits BCR signaling, demonstrating reduced proliferation and survival of the malignant B cells and significantly prolonged survival of the treated Eμ-TCL1 transgenic mouse. Moreover, the effect of R788 was found to be selective for the malignant clones, since no disturbance in the production of normal B lymphocytes was observed [2].
Clinical trial: In a phase II clinical trial, R788 treatment effectively improved American College of Rheumatology response rates in patients with eumatoid arthritis [3].
