compound introduction
AG-490 (Tyrphostin AG 490)是EGFR抑制剂，IC50为100nM，比对ErbB2的抑制性高135倍，对Lck，Lyn，Btk，Syk和Src无活性。Tyrphostin AG has been used to block IL-6 cytokine signaling to study its effects on glial cell reactivity. AG 490 has also been used as a JAK2 inhibitor in human umbilical vein endothelial cells AG-490 (Tyrphostin AG 490) is an inhibitor of EGFR with IC50 of 0.1 μM, 135-fold more selective for EGFR versus ErbB2, also inhibits JAK2 with no activity to Lck, Lyn, Btk, Syk and Src. Tyrphostin AG has been used to block IL-6 cytokine signaling to study its effects on glial cell reactivity. AG 490 has also been used as a JAK2 inhibitor in human umbilical vein endothelial cells
