    Product Description

    SPI 112Me is a prodrug form of the Src homology region 2 domain-containing phosphatase 2 (SHP-2) inhibitor SPI 112 (Item No. 29474).1 It is hydrolyzed by esterases intracellularly to form SPI 112. SPI 112Me inhibits the protein tyrosine phosphatase (PTP) activity of SHP-2 containing a constitutively activating glutamate-to-lysine substitution at position 76 (SHP-2E76K) in TF-1 leukemia cells expressing the mutant enzyme. SPI 112Me (20 µM) inhibits Paxillin dephosphorylation, ERK1/2 activation, and cell migration in EGF-stimulated MDA-MB-468 breast cancer cells.

    WARNING This product is not for human or veterinary use.
