DiseasePTN11_HUMAN Defects in PTPN11 are the cause of LEOPARD syndrome type 1 (LEOPARD1) [MIM: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.[1] [2] [3] [4] [5] [6] [7] Defects in PTPN11 are the cause of Noonan syndrome type 1 (NS1) [MIM: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.[8] [9] [10] [11] [12] [13] [14] [15] [16] [17] [18] [19] Defects in PTPN11 are a cause of juvenile myelomonocytic leukemia (JMML) [MIM:607785. JMML is a pediatric myelodysplastic syndrome that constitutes approximately 30% of childhood cases of myelodysplastic syndrome (MDS) and 2% of leukemia. It is characterized by leukocytosis with tissue infiltration and in vitro hypersensitivity of myeloid progenitors to granulocyte-macrophage colony stimulating factor.[20] Defects in PTPN11 are a cause of metachondromatosis (MC) [MIM:156250. It is a skeletal disorder with radiologic fetarures of both multiple exostoses and Ollier disease, characterized by the presence of multiple enchondromas and osteochondroma-like lesions.[21] FunctionPTN11_HUMAN Acts downstream of various receptor and cytoplasmic protein tyrosine kinases to participate in the signal transduction from the cell surface to the nucleus. Dephosphorylates ROCK2 at Tyr-722 resulting in stimulatation of its RhoA binding activity.[22] [23] [24] Publication Abstract from PubMedProtein tyrosine phosphatase SHP2 is an oncoprotein associated with cancer as well as a potential immune modulator due to its role in the programmed cell death PD-L1/PD-1 pathway. In the preceding manuscript, we described the optimization of a fused, bicyclic screening hit for potency, selectivity, and physicochemical properties in order to further expand the chemical diversity of allosteric SHP2 inhibitors. In this second manuscript, we describe the further expansion of our approach, morphing the fused, bicyclic system into a novel monocyclic pyrimidinone scaffold through our understanding of SAR and use of structure-based design. These studies led to the identification of SHP394 (1), an orally efficacious inhibitor of SHP2, with high lipophilic efficiency, improved potency and enhanced pharmacokinetic properties. We also report other pyrimidinone analogs with favorable pharmacokinetic and potency profiles. Overall, this work improves upon our previously described allosteric inhibitors, and exemplifies and extends the range of permissible chemical templates that inhibit SHP2 via the allosteric mechanism. 6-Amino-3-Methylpyrimidinones as Potent, Selective, and Orally Efficacious SHP2 Inhibitors.,Sarver P, Acker MG, Bagdanoff J, Chen Z, Chen YP, Chan H, Firestone B, Fodor M, Fortanet J, Hao H, Hentemann M, Kato M, Koenig R, LaBonte LR, Liu G, Liu S, Liu C, McNeill E, Mohseni M, Sendzik M, Stams T, Spence S, Tamez V, Tichkule R, Towler CS, Wang H, Wang P, Williams SL, Yu B, LaMarche MJ J Med Chem. 2019 Jan 28. doi: 10.1021/acs.jmedchem.8b01726.
