| Hazard Information | Back Directory | [Usage]
AG 490 is a potent epidermal growth factor receptor kinase autophosphorylation inhibitor with an IC50 of 100 nM and 56.8 μM for EGFR and JAK, respectively. | [Biological Activity]
Selective inhibitor of EGF receptor tyrosine kinase (IC 50 values are 2 and 13.5 μ M for EGFR and ErbB2 respectively). Inhibitor of JAK2, JAK3/STAT, JAK3/AP-1 and JAK3/MAPK pathways and potently inhibits cytokine-independent cell growth in vitro and tumor cell invasion in vivo . | [Description]
AG-490 (133550-30-8) is a potent inhibitor of the JAK2 tyrosine kinase. In acute lymphoblastic leukemia (ALL) cells, which abundantly express JAK-2, AG-490 dose-dependently blocked cell growth, induced apoptosis and inhibited DNA synthesis. Blocks the growth of all pre-B ALL cells with no effect on normal B or T cells. Does not significantly inhibit other kinases such as Lck, Lyn, Btk, Syk and Src. Reduces liver injury in LPS-induced shock.3 AG-490 is a useful tool for exploring the role of JAK2/STAT3 pathway in physiologic processes.4 | [Uses]
AG 490 is a potent epidermal growth factor receptor kinase autophosphorylation inhibitor with an IC50 of 100 nM and 56.8 μM for EGFR and JAK, respectively. | [Definition]
ChEBI: Tyrphostin B42 is a monocarboxylic acid amide obtained by formal condensation of the carboxy group of (2E)-2-cyano-3-(3,4-dihydroxyphenyl)prop-2-enoic acid with the amino group of benzylamine. It has a role as an EC 2.7.10.2 (non-specific protein-tyrosine kinase) inhibitor, an antioxidant, a STAT3 inhibitor, an anti-inflammatory agent, an apoptosis inducer and a geroprotector. It is an enamide, a monocarboxylic acid amide, a nitrile, a member of catechols and a secondary carboxamide. | [Biochem/physiol Actions]
Jak-2 protein tyrosine kinase (PTK) inhibitor. Inhibits interleukin 2 (IL-2) driven mitogenesis and triggers apoptosis of tumor cells in Sezary syndrome, a leukemic variant of cutaneous T cell lymphoma. | [storage]
