Selective Inhibitors of the Protein Tyrosine Phosphatase Shp2 Block Cellular Motility and Growth of Cancer Cells in Vitro and in Vivo.
Chemmedchem, 10:815-, 2015

PubMed Abstract: Selective inhibitors of the protein tyrosine phosphatase SHP2 (src homology region 2 domain phosphatase; PTPN11), an enzyme that is deregulated in numerous human tumors, were generated through a combination of chemical synthesis and structure-based rational design. Seventy pyridazolon-4-ylidenehydrazinyl benzenesulfonates were prepared and evaluated in enzyme assays. The binding modes of active inhibitors were simulated in silico using a newly generated crystal structure of SHP2. The most powerful compound, GS-493 (4-{(2Z)-2-[1,3-bis(4-nitrophenyl)-5-oxo-1,5-dihydro-4H-pyrazol-4-yliden]hydrazino}benzenesulfonic acid; 25) inhibited SHP2 with an IC50 value of 71±15 nM in the enzyme assay and was 29- and 45-fold more active toward SHP2 than against related SHP1 and PTP1B. In cell culture experiments compound 25 was found to block hepatocyte growth factor (HGF)-stimulated epithelial-mesenchymal transition of human pancreatic adenocarcinoma (HPAF) cells, as indicated by a decrease in the minimum neighbor distances of cells. Moreover, 25 inhibited cell colony formation in the non-small-cell lung cancer cell line LXFA 526L in soft agar. Finally, 25 was observed to inhibit tumor growth in a murine xenograft model. Therefore, the novel specific compound 25 strengthens the hypothesis that SHP2 is a relevant protein target for the inhibition of mobility and invasiveness of cancer cells.
