Abstract
Description
NEW POLYMORPHIC FORMS OF THE SHP2 INHIBITOR AND USES THEREOFFIELD OF THE INVENTION
[0001] The present disclosure relates to polymorph forms, salts and salts forms of the SHP2 inhibitor, processes thereof, pharmaceutical compositions thereof, and use of polymorph forms, salts and polymorph forms thereof, and pharmaceutical compositions for the treatment of a SHP2 mediated disease.BACKGROUND OF THE INVENTION
[0002] SHP2 (The Src Homolgy-2 phosphatase) 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. The two SH2 domains control the subcellular localization and functional regulation of SHP2. In its inactive state, the N-terminal SH2 domain blocks the PTP domain and this autoinhibition is relieved by binding of the SH2 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.
[0003] 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.
[0004] The hyperactivation of SHP2 catalytic activity caused by either germline or somatic mutations in PTPN11 has been identified in patients with Noonan syndrome, Leopard syndrome, juvenile myelomonocytic leukemias, myelodysplastic syndrome, B cell acute lymphoblastic leukemia / lymphoma, and acute myeloid leukemia. In addition, activating mutations 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 the activated or up-regulated SHP2 protein in human cancers and other disease make SHP2 an excellent target for development of novel therapies.
[0005] Many pharmaceutically active organic compounds can crystallize in more than one type of three-dimensional crystal structure. That is, the compounds may crystallize in different crystalline forms. This phenomenon (identical chemical structure but different crystalline structure) is referred to as polymorphism, and the species having different molecular structures are referred to as polymorphs.
[0006] Polymorphs of a particular organic pharmaceutical compound may have different physical properties, such as solubility and hygroscopicity, due to their distinct three-dimensional crystal structures. However, it is generally not possible to predict whether a particular organic compound will form different crystalline forms, let alone predict the structure and properties of the crystalline forms themselves. The discovery of a new crystalline or polymorph form of a pharmaceutically useful compound may provide a new opportunity for improving the overall characteristics of a pharmaceutical product. It enlarges the repertoire of materials that a formulation scientist has available for designing. It may be advantageous when this repertoire is enlarged by the discovery of new polymorphs of a useful compound.
