SHP2 inhibitors Synthesis Activity evaluation Molecular docking MD simulation
摘要：

Overexpression or gene mutation of SHP2 is closely linked with a variety of cancers and has been identified as a crucial anticancer target. In the study, we took SHP2 allosteric inhibitor SHP099 as the lead compound, and 32 1,3,4-thiadiazole derivatives were identified as selective allosteric inhibitors of SHP2. In vitro enzyme activity test showed that some compounds had high inhibition on full length SHP2, and almost no activity on homologous protein SHP1, exhibiting high selectivity. Compound YF704 (4w) had the best inhibition activity, with IC50 value of 0.25 & PLUSMN; 0.02 & mu;M, and also showed strong inhibitory activity on SHP2-E76K and SHP2-E76A, with IC50 values of 6.88 & PLUSMN; 0.69 & mu;M and 1.38 & PLUSMN; 0.12 & mu;M, respectively. CCK8 proliferation test found that multiple compounds would effectively inhibit the proliferation of a variety of cancer cells. Among them, the IC50 values of compound YF704 on MV4-11 and NCI-H358 cells were 3.85 & PLUSMN; 0.34 & mu;M and 12.01 & PLUSMN; 0.62 & mu;M, respectively. Specially, these compounds were sensitive to NCI-H358 cells containing KRASG12C mutation, thus overcoming the problem that SHP099 was insensitive to such cells. Apoptosis experiment showed that compound YF704 would effectively induce apoptosis of MV4-11 cells. Western blot showed that compound YF704 would downregulate the phosphorylation levels of Erk1/2 and Akt in MV4-11 and NCI-H358 cells. Molecular docking study show that compound YF704 would effectively bind to the allosteric region of SHP2 and form hydrogen bond interactions with key residues Thr108, Arg111 and Phe113. Molecular dynamics study further revealed the binding mechanism of SHP2 and compound YF704. In conclusion, we hope to provide potential SHP2 selective inhibitors and provide valuable clues for cancer treatment.
