Tyrphostin AG-490 (#14704) Datasheet Without Images Cell Signaling Technology

For Research Use Only. Not for Use in Diagnostic Procedures.

Background

Tyrphostin AG-490 is a membrane soluble protein tyrosine kinase inhibitor that primarily blocks Jak2 (IC₅₀ = 10 μM) and Jak3 (IC₅₀= 20 μM) kinases (1,2). Research studies demonstrate that tyrphostin AG-490 inhibits proliferation and expansion of T cells (3). Unlike many other kinase inhibitors, tyrphostin AG-490 does not block a number of lymphocytic tyrosine kinases, such as Lck, Lyn, Btk, Syk, Jak1, Tyk2, or Src kinase (1,4). Additional studies indicate that tyrphostin AG-490 also selectively inhibits the EGFR (IC₅₀= 2 μM) and ErbB2 (IC₅₀= 13.5 μM) receptor tyrosine kinases (5).

Molecular Formula

C₁₇H₁₄N₂O₃

Molecular Weight

294.3 g/mol

Purity

>99%

CAS

134036-52-5

Solubility

Soluble in DMSO at 200mg/ml and EtOH at 16mg/ml.

Storage

Store lyophilized or in solution at -20ºC, desiccated. In lyophilized form, the chemical is stable for 24 months. Once in solution, use within 3 months to prevent loss of potency. Aliquot to avoid multiple freeze/thaw cycles.

Directions for Use

Tyrphostin AG-490 is supplied as a lyophilized powder. For a 50 mM stock, reconstitute the 10 mg in 679.58 μl DMSO. Working concentrations and length of treatment can vary depending on the desired effect, but it is typically used at 10-100 μM for 1-24 hr.
