AG-490 is an inhibitor of tyrosine kinases .
As a member of the tyrphostin family, AG-490 is reported to have inhibitory activity against many kinases. It can inhibit the hyperactive JAK2 in B cell precursors of ALL patients, inhibit cytokine-induced activation of JAK2 in eosinophils and suppresses the activation of STAT3 in mycosis fungoides-derived T cells. AG-490 is also found to target JAK3 and its downstream STAT and MAPK signaling pathways. In the IL-2-dependent T cell line, D10, AG-490 suppresses IL-2-induced cell proliferation with IC50 value of 25μM without affecting IL-2R chain expression. It also inhibits IL-2-modulated phosphorylation of STAT5a and STAT5b with IC50 value of 50μM-70μM. Moreover, AG-490 reduces IL-2-induced DNA binding by 78%, 65% and 65% for STAT5a/5b, STAT1 and STAT3, respectively. All these show that AG-490 may provide a beneficial therapeutic by suppressing immunopathological states .
