BMS-243117 is an effective selective LCK inhibitor with good cell activity (IC(50)=1.1 microM) and inhibition of T cell proliferation, which has great potential for therapeutic immunosuppression and the treatment of diseases such as rheumatoid arthritis a
RK-20448 is an ATP-competitive inhibitor of Lck, Src, KDR/VEGF2R, and Tie-2. It also inhibits BLK, Csk, Fyn, and Lyn. RK-20448 is the cis isomer of A-419259
BB-F-Yne is a cell-permeable derivative of the protein arginine diminase (PAD) inhibitor BB-Cl-amidine that contains an alkyne moiety for use in click chemistry reactions. BB-F-Yne inhibits PAD1-4 with Kinact/KI values of 900, 1,200, 3,400, and 3,750 M-1min-1, respectively. It has been used for labeling PADs in cell-free and cell-based assays, followed by click reactions with azide-modified TAMRA or biotin reporters.
