Src homology-2-containing protein tyrosine phosphatase 2(SHP2)is a promising therapeutic target for cancer *** this work,we presented the structure-guided design of 5,6-fused bicyclic allosteric SHP2 inhibitors,leading to the identification of pyrazolopyrazine-based tK-642 as a highly potent,selective,orally bioavailable allosteric SHP2 inhibitor(SHP2Wt IC_(50)=2.7 nmol/L)with favorable pharmacokinetic profiles(F=42.5%;t_(1/2)=2.47 h).Both dual inhibition biochemical assay and docking analysis indicated that tK-642 likely bound to the“tunnel”allosteric site of ***-642 could effectively suppress cell proliferation(KYSE-520 cells IC_(50)=5.73μmol/L)and induce apoptosis in esophageal cancer cells by targeting the SHP2-mediated AKt and ERK signaling ***,oral administration of tK-642 also demonstrated effective anti-tumor effects in the KYSE-520 xenograft mouse model,with a t/C value of 83.69%.Collectively,tK-642 may warrant further investigation as a promising lead compound for the treatment of esophageal cancer.
