Description

Substituted pyridine compound, preparation method and application thereof

Technical Field

The invention relates to the field of medicinal chemistry, in particular to a substituted pyridine compound serving as an SHP2 inhibitor, a preparation method thereof, a medicinal composition and application thereof in treating SHP2 enzyme-related diseases.

Background

SHP2(src homology 2 domain stabilizing phospho-side phosphatase 2) is a protein tyrosine phosphatase encoded by the gene PTPN11, structurally comprising two N-terminal SH2 (Srchology 2) domains, a Protein Tyrosine Phosphatase (PTP) catalytic domain and a C-terminal tail rich in proline groups and tyrosine phosphorylation sites. In the basal state, the SHP2 adopts a self-inhibiting configuration, with the N-SH2 domain sterically hindering access of the substrate to the active site. When ligand containing phosphorylated tyrosine residue is specifically combined with N-SH2 domain, the configuration of SHP2 is changed, the catalytic active site of PTP domain is exposed, and the inhibition of the catalytic active site is eliminated, so that the signaling cascade reaction initiated by tyrosine phosphorylation is initiated.

SHP2 is present in the cytoplasm and transduces signals from multiple receptor-tyrosine kinases in cells, and is therefore involved in a cascade of many oncogenic signals (e.g., RAS-ERK, PI3K-AKT, JAK-STAT). SHP2 has been reported to bind RAS and undergo a dephosphorylation reaction, enhancing the binding force between RAS-RAF, thereby activating downstream RAS/ERK/MAPK proliferation signaling pathways (Bunda, s., equivalent. nat. Commun.6, 8859.). Additionally, SHP2 has been reported in the literature (Li, J., et al. cancer Res.75,508-518.) to be involved in the programmed T cell death/checkpoint pathway (PD-L1/PD-1). Activated PD-1 recruits SHP2, dephosphorylates co-stimulatory receptor CD28, inhibits T cell function, and promotes immune escape. In view of the recent clinical success of anti-PD-L1/PD-1 therapy, there has been great interest in the development of small molecule SHP2 inhibitors for cancer immunotherapy.

Some SHP2 inhibitors have been reported (see, e.g., WO2015107493a1), but there remains a need in the art for new SHP2 inhibitors, particularly SHP2 inhibitors with high activity and other advantageous properties.

In compounds having one or more (e.g., one, two, three, or four) asymmetric centers, they can give rise to racemic mixtures, single enantiomers, diastereomeric mixtures, and individual diastereomers. Certain individual molecules may also exist as geometric isomers (cis/trans). Similarly, the compounds of the invention may exist as mixtures of two or more structurally different forms (commonly referred to as tautomers) in rapid equilibrium. Representative examples of tautomers include keto-enol tautomers, phenol-keto tautomers, nitroso-oxime tautomers, imine-enamine tautomers, and the like.

The use of solid or dashed wedges to depict bonds to asymmetric carbon atoms is intended to indicate that the stereoisomers shown are present. When present in a racemic mixture, solid and dotted wedges are used to define the relative stereochemistry, not the absolute stereochemistry. Unless otherwise indicated, the compounds of the present invention may exist in the form of stereoisomers (which include cis and trans isomers, optical isomers (e.g., R and S enantiomers), diastereomers, geometric isomers, rotamers, conformers, atropisomers, and mixtures thereof). The compounds of the present invention may exhibit more than one type of isomerization and consist of mixtures thereof (e.g., racemic mixtures and diastereomeric pairs).

One skilled in the art will recognize nitrogen-containing heterocycles that are capable of forming N-oxides. Those skilled in the art will also recognize that tertiary amines are capable of forming N-oxides. Synthetic methods for preparing N-oxides of heterocycles and tertiary amines are well known to those skilled in the art and include oxidation of heterocycles and tertiary amines with peroxy acids such as peracetic and m-chloroperbenzoic acid (mCPBA), hydrogen peroxide, alkyl hydroperoxides such as t-butyl hydroperoxide, sodium perborate, and dioxiranes (dioxiranes) such as dimethyldioxirane. These methods for preparing N-oxides have been widely described and reviewed in the literature, see for example: l.l.gilchrist, Comprehensive Organic Synthesis, vol.7, pp748-750(a.r.katritzky and a.j.boulton, eds., Academic Press); and G.W.H.Cheeseman and E.S.G.Werstuk, Advances in Heterocyclic Chemistry, vol.22, pp 390-.
