商品描述
SPI-112, the SPI-112 methyl ester analog, can inhibit cellular Shp2 PTP activity. SPI-112 bound to Shp2 by surface plasmon resonance (SPR) and displayed competitive inhibitor kinetics to Shp2.

In vitro(体外研究)
SPI-112 has a polar -NO2 or a negatively charged -COOH group and has no detectable cellular activity, suggesting that SPI-112 is not cell permeable.
In surface plasmon resonance (SPR) binding assay, SPI-112 displays a 1:1 stoichiometric binding kinetics to SHP2 with a kinetic constant KD of 1.30 µM. Enzyme kinetic data obtained with SPI-112 are best fitted with the competitive inhibition model (Ki of 0.8 µM), suggesting that SPI-112 interacts with the catalytic site of SHP2.
