A small molecule inhibitor targeting SHP2 mutations for the lung carcinoma

The RAS/mitogen-activated protein kinase(MAPK)pathway disorder induced by the missense mutations in the tyrosine-protein phosphatase non-receptor type 11(PTPN11)gene which resulted in the nonreceptor protein tyrosine phosphatase SHP2 dysfunction has been reported in many lung cancer cases.Moreover,the Src homology region 2(SH2)-containing protein tyrosine phosphatase 2(SHP2)mutation or deletion triggers multiple signaling pathway dysfunctions including RAS/MAPK,RAS/extracellular-signal-regulated kinase(ERK),phosphatidylinositol 3-kinase(PI3K)/protein kinase B(AKT),Janus kinase/signal transducers and activators of transcription(JAK/STAT)and Hippo/yes-associated protein(YAP)which affect the expression of growth factors,cytokines and hormones.In recent years,the developing of the small molecule SHP2 inhibitors received a lot of attention.In this review,we summarize the recent years'progresses of the SHP2 inhibitors development for the lung cancer treatment.
