Lck inhibitor 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).
Lck inhibitor II is a cell-permeable, ATP binding site-targeting, tri-substituted pyrimidine that acts as a highly potent Lck (lymphocyte specific kinase) inhibitor
