Definitions

  • This invention relates to certain novel heterocyclic derivatives (Formula I) as SHP2 inhibitors which is shown as formula I, their synthesis and their use for treating a SHP2 mediated disorder. More particularly, this invention is directed to fused heterocyclic derivatives useful as inhibitors of SHP2, methods for producing such compounds and methods for treating a SHP2-mediated disorder.
  • SHP2 The Src Homolgy-2 phosphatease
  • SHP2 is a non-receptor protein tyrosine phosphatase encoded by the PTPN11 gene that harbors a classical tyrosine phosphatase domain and two N-terminal Src homology 2 (SH2) domains and a C-terminal tail.
  • SH2 N-terminal Src homology 2
  • the two SH 2 domains control the subcellular localization and functional regulation of SHP2.
  • the N-terminal SH 2 domain blocks the PTP domain and this autoinhibition is relieved by binding of the SH 2 domains to specific phosphotyrosine sites on receptors or receptor-associated adaptor proteins.
  • the stimulation for example, by cytokines or growth factors leads to exposure of the catalytic site resulting in enzymatic activation of SHP2.
  • SHP2 is widely expressed and participated in multiple cell signaling processes, such as the Ras-Erk, PI3K-Akt, Jak-Stat, Met, FGFR, EGFR, and insulin receptors and NF-kB pathways, in which plays an important role in proliferation, differentiation, cell cycle maintenance and migration.
  • the hyperactivation of SHP2 catalytic activity caused by either germline or somatic mutations in PTPN11 have been identified in patients with Noonan syndrome, Leopard syndrome, juvenile myelomonocytic leukemias, myelodysplastic syndrome, B cell acute lymphoblastic leukemia/lymphoma, and acute myeloid leukemia.
  • activating mutation s of PTPN11 have been found in solid tumors as well, such as lung cancer, colon cancer, melanoma, neuroblastoma, and hepatocellular carcinoma. Therefore, the presence of activated or up-regulated SHP2 protein in human cancers and other disease make SHP2 an excellent target for development of novel therapies.
  • the compounds of the present invention fulfill the need of small molecules in order to inhibit the activity of SHP2.
  • the present invention relates to certain novel heterocyclic compounds useful as SHP2 inhibitors and their use for treating a SHP2 mediated disorder.
  • the compounds of the invention have the general structure as Formula I or a pharmaceutically acceptable salt:
  • ring A is a 5-12 membered aromatic ring, a 5-12 membered heteroaromatic ring or a 5-12 membered heterocyclic ring, and each of the ring systems is independently optionally substituted or unsubstituted;
  • G is selected from absent, S, —SO—, —SO 2 —, O, —CO—, —NR G —, —NR G —SO 2 —,
