Abstract

SHP2 is a nonreceptor protein tyrosine phosphatase (PTP) encoded by the PTPN11 gene involved in cell growth and differentiation via the MAPK signaling pathway. SHP2 also purportedly plays an important role in the programmed cell death pathway (PD-1/PD-L1). Because it is an oncoprotein associated with multiple cancer-related diseases, as well as a potential immunomodulator, controlling SHP2 activity is of significant therapeutic interest. Recently in our laboratories, a small molecule inhibitor of SHP2 was identified as an allosteric modulator that stabilizes the autoinhibited conformation of SHP2. A high throughput screen was performed to identify progressable chemical matter, and X-ray crystallography revealed the location of binding in a previously undisclosed allosteric binding pocket. Structure-based drug design was employed to optimize for SHP2 inhibition, and several new protein-ligand interactions were characterized. These studies culminated in the discovery of 6-(4-amino-4-methylpiperidin-1-yl)-3-(2,3-dichlorophenyl)pyrazin-2-amine (SHP099, 1), a potent, selective, orally bioavailable, and efficacious SHP2 inhibitor.

  • SHP099 binds simultaneously to the interfaces of the N-SH2, C-SH2 and PTP structural domains of SHP2, creating hydrogen bonding interactions with key amino acid residues (Arg111, Phe113 and Glu250) and stabilizing SHP2 in a closed, self-inhibited conformation.

    “It binds simultaneously to the interfaces of the N-SH2, C-SH2 and PTP structural domains of SHP2, creating hydrogen bonding interactions with key amino acid residues (Arg111, Phe113 and Glu250) and stabilizing SHP2 in a closed, self-inhibited conformation.288”
  • SHP099 has favorable physicochemical properties, showing selectivity against 21 phosphatases and 66 kinases.

    “SHP099 has favorable physicochemical properties, showing selectivity against 21 phosphatases and 66 kinases.”
  • This mechanism of action inhibits SHP2 activity through a metastable mechanism, leading to the inhibition of RAS/ERK signaling and suppressing RTK-driven proliferation of human cancer cells in vitro.

    “This mechanism of action inhibits SHP2 activity through a metastable mechanism, leading to the inhibition of RAS/ERK signaling and suppressing RTK-driven proliferation of human cancer cells in vitro.286–288”
  • SHP2 inhibitors stabilize the auto-inhibited conformation of SHP2 and disrupt SOS1-mediated nucleotide exchange of KRAS.

    “SHP2 inhibitors stabilize the auto-inhibited conformation of the enzyme and thereby disrupt SOS1-mediated nucleotide exchange of KRAS (11, 35, 36).”
  • SHP2 inhibitors stabilize an inhibited enzyme conformation and disrupt the nucleotide exchange of KRAS mediated by SOS1.

    “SHP2 inhibitors stabilize an inhibited enzyme conformation and, thus, disrupt the nucleotide exchange of KRAS mediated by SOS1 [56,59,60].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
