Abstract
Cellular biological activities are tightly controlled by intracellular signaling processes initiated by extracellular signals. Protein tyrosine phosphatases, which remove phosphate groups from tyrosine phosphorylated signaling molecules, play equally important tyrosine roles as protein kinases in signal transduction. SHP-2, a cytoplasmic SH2 domain containing protein tyrosine phosphatase, is involved in the signaling pathways of a variety of growth factors and cytokines. Recent studies have clearly demonstrated that this phosphatase plays an important role in transducing signal relay from the cell surface to the nucleus, and is a critical intracellular regulator in mediating cell proliferation and differentiation.
Description
BACKGROUND

Src homology region 2 (SH2)-containing protein tyrosine phosphatase 2 (SHP2) is a protein tyrosine phosphatase encoded by the PTPN11 gene. SHP2 contains two Src homology 2 (SH2) NH2-terminal domains and a C-terminal protein-tyrosine phosphatase domain. It is ubiquitously expressed in various tissues and cell types. SHP2 plays an important role in diverse signaling pathways to regulate cellular biological processes and is involved in the signaling pathways of a variety of growth factors and cytokines. Within a single signaling pathway, SHP2 can play both positive (signal enhancing) and negative (signal diminishing) roles in intracellular signaling processes. SHP2 is believed to function by dephosphorylating its associated signaling molecules, thereby attenuating the local signaling flow. However, the main effect of SHP2 action in most signaling pathways (e.g., growth factor, cytokine, and extracellular matrix receptors) is to enhance signal transduction. For example, SHP2 is a positive regulator of the ERK/MAPK signaling pathway, playing a key role in regulating cellular proliferation and survival. (For a review of SHP2 phosphatase, see, e.g, K. S. Grossman et al., Adv. Cancer Res. 2010, 106, 53-89; and references cited therein.)


In the basal state, SHP2 is normally auto-inhibited due to intramolecular interactions between its N-terminal SH2 (N—SH2) domain and its catalytic (PTP) domain, which blocks access to the catalytic site. Activating proteins that interact with the SH2 domains induce a conformational change that reverses this inhibition and allows substrate access to the catalytic site. Mutations in the PTPN11 gene that affect the N—SH2 or PTP domain residues involved in basal inhibition of SHP2 result in more readily activatable forms of SHP2 protein, which can lead to unregulated or increased SHP2 activity. Such activated mutants of SHP2 have been associated with developmental disorders such as Noonan syndrome, where nearly all mutated forms of SHP2 demonstrate increased PTP activity. Thus, there is a need for SHP2 phosphatase inhibitor compounds and methods for treating cancer and other disorders with these compounds.

The compounds described herein can function as allosteric inhibitors and block the activation of SHP2 by targeting the auto-inhibited conformation of SHP2.


The compounds described herein can also inhibit SHP2 function through incorporation into agents that catalyze the destruction of SHP2. For example, the compounds can be incorporated into proteolysis targeting chimeras (PROTACs). A PROTAC is a bifunctional molecule, with one portion capable of engaging an E3 ubiquitin ligase, and the other portion having the ability to bind to a target protein meant for degradation by the cellular protein quality control machinery. Recruitment of the target protein to the specific E3 ligase results in its tagging for destruction (i.e., ubiquitination) and subsequent degradation by the proteasome. Any E3 ligase can be used. The portion of the PROTAC that engages the E3 ligase is connected to the portion of the PROTAC that engages the target protein via a linker which consists of a variable chain of atoms. Recruitment of SHP2 to the E3 ligase will thus result in the destruction of the SHP2 protein. The variable chain of atoms can include, for example, rings, heteroatoms, and/or repeating polymeric units. It can be rigid or flexible. It can be attached to the two portions described above using standard techniques.


The compounds described herein can be linked to one end of a variable chain, while the other end of the variable chain can be bound to the E3 ligase. Recruitment of SHP2 to the ligase will thus result in the destruction of the SHP2 protein.

SHP2 Allosteric Inhibition Assay.


SHP2 is allosterically activated through binding of bis-tyrosyl-phorphorylated peptides to its Src Homology 2 (SH2) domains. The latter activation step leads to the release of the auto-inhibitory interface of SHP2, which in turn renders the SHP2 protein tyrosine phosphatase (PTP) active and available for substrate recognition and reaction catalysis. The catalytic activity of SHP2 was monitored using the surrogate substrate DiFMUP in a prompt fluorescence assay format.


More specifically, the phosphatase reactions were performed at room temperature in 96-well black polystyrene plate, flat bottom, low flange, non-binding surface (Corning, Cat #3575) using a final reaction volume of 50 μl and the following assay buffer conditions: 60 mM HEPES, pH 7.2, 75 mM NaCl, 75 mM KCl, 1 mM EDTA 0.005% Brij-35, 5 mM DTT.


The inhibition of SHP2 by compounds of the disclosure (concentrations varying from 0.003-100 μM) was monitored using an assay in which 0.25 nM of SHP2 was incubated with of 0.5 μM of peptide IRSl_pY1172(dPEG8)pY1222 (sequence: H2N-LN(pY)IDLDLV(dPEG8)LST(pY)ASINFQK-amide). After 30-60 minutes incubation at 25° C. the surrogate substrate DiFMUP (Invitrogen, cat #D6567, 100 μM final) was added to the reaction and the conversion of DiFMUP to 6,8-difluoro-7-hydroxyl-4-methylcoumarin (DiFMU) was monitored continuously for 10 minutes with excitation at 355 nm and emission at 460 nm using a microplate reader (PolarStar, BMG). The inhibitor dose response curves were analyzed using normalized IC50 regression curve fitting with control based normalization.


Biochemical assay results for compounds of the disclosure are shown in examples and Table 1. In Table 1, A means an IC50 of less than 1 μM: B means an IC50 equal to 1 μM but less than 10 μM; and C means an IC50 of 10 μM or more.
