Description: | SPI-112 is a potent, selective and competitive SHP2 (PTPN11) inhibitor with IC50s of 1 μM, 18.3 μM and 14.5 μM for SHP2, protein tyrosine phosphatase (PTP) and PTP1B, respectively[1][2]. |
In Vitro: | 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]. |
