Lckinhibitor 2 is a bis-anilinopyrimidine inhibitor of tyrosine kinases including LCK, BTK, LYN, SYK, and TXK (IC50s: 13nM, 9nM, 3nM, 26nM, and 2nM for Lck, Btk, Lyn, Btk, and Txk respectively).
Lckinhibitor II is a cell-permeable, ATP binding site-targeting, tri-substituted pyrimidine that acts as a highly potent Lck (lymphocyte specific kinase) inhibitor
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
