[[http://www.uniprot.org/uniprot/PTN11_HUMAN PTN11_HUMAN]] Defects in PTPN11 are the cause of LEOPARD syndrome type 1 (LEOPARD1) [MIM:[http://omim.org/entry/151100 151100]]. It is an autosomal dominant disorder allelic with Noonan syndrome. The acronym LEOPARD stands for lentigines, electrocardiographic conduction abnormalities, ocular hypertelorism, pulmonic stenosis, abnormalities of genitalia, retardation of growth, and deafness.<ref>PMID:12058348</ref> <ref>PMID:14961557</ref> <ref>PMID:15389709</ref> <ref>PMID:15520399</ref> <ref>PMID:15121796</ref> <ref>PMID:15690106</ref> <ref>PMID:16679933</ref> Defects in PTPN11 are the cause of Noonan syndrome type 1 (NS1) [MIM:[http://omim.org/entry/163950 163950]]. Noonan syndrome (NS) is a disorder characterized by dysmorphic facial features, short stature, hypertelorism, cardiac anomalies, deafness, motor delay, and a bleeding diathesis. Some patients with Noonan syndrome type 1 develop multiple giant cell lesions of the jaw or other bony or soft tissues, which are classified as pigmented villomoduolar synovitis (PVNS) when occurring in the jaw or joints. Note=Mutations in PTPN11 account for more than 50% of the cases. Rarely, NS is associated with juvenile myelomonocytic leukemia (JMML). NS1 inheritance is autosomal dominant.<ref>PMID:11704759</ref> <ref>PMID:11992261</ref> <ref>PMID:12325025</ref> <ref>PMID:12161469</ref> <ref>PMID:12529711</ref> <ref>PMID:12634870</ref> <ref>PMID:12739139</ref> <ref>PMID:12960218</ref> <ref>PMID:12717436</ref> <ref>PMID:15384080</ref> <ref>PMID:15948193</ref> <ref>PMID:19020799</ref> Defects in PTPN11 are a cause of juvenile myelomonocytic leukemia (JMML) [MIM:[http://omim.org/entry/607785 607785]].

SHP2, a cytoplasmic protein-tyrosine phosphatase encoded by the PTPN11 gene, is involved in multiple cell signaling processes including Ras/MAPK and Hippo/YAP pathways. SHP2 has been shown to contribute to the progression of a number of cancer types including leukemia, gastric, and breast cancers. It also regulates T-cell activation by interacting with inhibitory immune checkpoint receptors such as the programmed cell death 1 (PD-1) and B- and T-lymphocyte attenuator (BTLA). Thus, SHP2 inhibitors have drawn great attention by both inhibiting tumor cell proliferation and activating T cell immune responses toward cancer cells. In this study, we report the identification of an allosteric SHP2 inhibitor 1-(4-(6-bromonaphthalen-2-yl)thiazol-2-yl)-4-methylpiperidin-4-amine (23) that locks SHP2 in a closed conformation by binding to the interface of the N-terminal SH2, C-terminal SH2, and phosphatase domains. Compound 23 suppresses MAPK signaling pathway and YAP transcriptional activity and shows antitumor activity in vivo. The results indicate that allosteric inhibition of SHP2 could be a feasible approach for cancer therapy.
