The Uses of AG 490
A potent and specific inhibitor of the Jak-2 tyrosine kinase. In acute lymphoblastic leukemia (ALL) cells which abundantly express JAK-2, AG-490 dose-dependently inhibited DNA synthesis, blocked cell growth and induced apoptosis. AG-490 does not significantly inhibit other kinases such as Lck, Lyn, Btk, Syk and Src. AG-490 is cell permeable and is active in vivo.
The Uses of AG 490
Tyrphostin B42 is used in acute lymphoblastic leukemia studies the compound has been reported to inhibit JAK2 from B cell precursors.
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.
