Tyrphostin AG 490- CAS 133550-30-8

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.
IC50 value: 0.1 uM (EGFR)[1]; 10 uM (JAK2) [2]
Target: EGFR
in vitro: Corresponding to the specific dose-dependent inhibition of constitutively activated JAK2 in pre-B acute leukemia (ALL) cells, AG-490 (5 μM) almost completely blocks the growth of all ALL cells by inducing programmed cell death, with no deleterious effect on normal hematopoiesis. AG-490 does not inhibit the activities of Lck, Lyn, Btk, Syk, and Src [2]. AG-490 significantly inhibits the constitutive activation of Stat3 in MOPC, MPC11, and S194 cells, leading to dramatic dose-dependent apoptosis [3].
in vivo: Administration of AG-490 drastically reduces the numbers of CD45+ and HLA-DR+ cells from 48 % and 46% in bone marrow of untreated mice, as well as 38% and 22% in the spleen of untreated mice to undetectale levels [2]. In vivo administration of AG-490 causes murine myeloma tumor cell apoptosis but does not inhibit IL-12-mediated macrophage activation and IFN-γ production by lymphocytes [3].
