Abstract

The thiophene [2,3-d]pyrimidine structure-like small molecules were discovered from structure-based virtual screening of 1 billion compounds. Base on Enzyme activity assay results, a SHP2-specific molecule inhibitor Comp#2 with IC50 of 1.174 μM, 85-fold more selective for SHP2 than the highly related SHP1 (IC50 > 100 μM). The compound can effectively inhibit SHP2-mediated cell signaling and Cancer cell proliferation, including cervix Cancer, human pancreatic Cancer, large cell lung Cancer, and mouse glioma cell. Moreover, the in vivo assay indicated that Comp#2 could inhibit cervix Cancer tumors growth in BABL/c mice. This work has shown the specific SHP2 Inhibitor can inhibit glioblastoma growth in vivo.
