Biological Activity
IC50: 1 μM (SHP2), 18.3 μM (PTP) and 14.5 μM (PTP1B)[2]
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[1].
?
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[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
