Abstract
The invention provides a NUAK inhibitor and application thereof. The invention provides a compound shown in a formula I, or a deuterated compound, or a stereoisomer or a pharmaceutically acceptable salt thereof, and application thereof in preparing a medicament for treating diseases. The compound provided by the invention has NUAK inhibition effect and provides a new medicinal possibility.
Description
Technical Field
The present invention relates to a novel class of compounds having NUAK inhibitory effect and their use in the treatment of disease.
Background
AMP-dependent protein kinases (AMP-activated protein kinase, AMPK) are an important class of protein kinases, the family of which has 12 members: MARK1, MARK2, MARK3, MARK4, MELK, QIK, QSK, SIK, BRSK1, BRSK2, NUAK1 and NUAK2.AMPK has important biological roles such as regulation of the immune system, regulation of gene transcription, control of cell polarity, and maintenance of cellular energy levels.
NUAK subtypes NUAK1 (ARK 5) and NUAK2 (SNARK) are important members of the AMPK family, are Ser/Thr kinases, can be phosphorylated and activated by LKB1 tumor suppressor protein kinase, and play an important role in cancer progression, cell adhesion, cell proliferation and metastasis, and glycometabolism. Studies have shown that NUAK subtypes are involved in many important functions, such as neuronal polarity and axonal branching, aging, cell adhesion, and control of embryonic development. NUAK also acts as a survival factor in MYC-driven tumors, promoting cancer cell invasion and controlling cell division by its ability to stimulate proliferation. Because of their critical function in cell signaling, their deregulation is associated with a number of serious diseases, including neurodegenerative diseases, metastatic cancers and diabetes. They are therefore potential therapeutic targets for metabolic diseases and cancers.
At present, no NUAK inhibitor medicine is marketed, so that the development of the medicine with NUAK inhibition activity has great market value.

The invention provides a compound shown in a formula I, or a deuterated compound, or a stereoisomer or a pharmaceutically acceptable salt thereof:

Definition of terms used in connection with the present invention: unless otherwise indicated, the initial definitions provided for groups or terms herein apply to the groups or terms throughout the specification; for terms not specifically defined herein, the meanings that one skilled in the art can impart based on the disclosure and the context.
"substituted" means that a hydrogen atom in the molecule is replaced with a different atom or group.
"further substituted" means that "substitution" may, but need not, occur, and that the description includes situations that may or may not occur.
The minimum and maximum values of the carbon atom content of the hydrocarbon groups are indicated by a prefix, e.g. prefix C a~b Alkyl indicates any alkyl group containing from "a" to "b" carbon atoms. Thus, for example, C 1~6 Alkyl refers to alkyl groups containing 1 to 6 carbon atoms.
"alkyl" means having the indicated number of ingredientsSaturated hydrocarbon chains of member atoms. The alkyl group may be linear or branched. Representative branched alkyl groups have one, two or three branches. The alkyl group may be optionally substituted with one or more substituents as defined herein. Alkyl groups include methyl, ethyl, propyl (n-propyl and isopropyl), butyl (n-butyl, isobutyl and tert-butyl), pentyl (n-pentyl, isopentyl and neopentyl) and hexyl. The alkyl group may also be part of other groups such as-O (C 1~6 Alkyl).
"alkylene" refers to a divalent saturated aliphatic hydrocarbon group having the indicated number of member atoms. C (C) a ~ b Alkylene refers to an alkylene group having a to b carbon atoms. Alkylene groups include branched and straight chain hydrocarbyl groups. For example, the term "propylene" may be exemplified by the following structure:likewise, the term "dimethylbutylene" may be exemplified, for example, by any of the following structures: />
"cycloalkyl", "cycloalkane" as used herein refers to a saturated or partially saturated cyclic group having multiple carbon atoms and no ring heteroatoms and having a single ring or multiple rings (fused, bridged). For polycyclic systems having aromatic and non-aromatic rings that do not contain ring heteroatoms, the term "cycloalkyl" (e.g., 5,6,7,8, -tetrahydronaphthalen-5-yl) applies when the point of attachment is at a non-aromatic carbon atom. The term "cycloalkyl" includes cycloalkenyl groups, such as cyclohexenyl. Examples of cycloalkyl groups include, for example, adamantyl, cyclopropyl, cyclobutyl, cyclohexyl, cyclopentyl, cyclooctyl, cyclopentenyl and cyclohexenyl. Examples of cycloalkyl groups comprising a multicycloalkyl ring system are dicyclohexyl, dicyclopentyl, bicyclooctyl, and the like. Two such bicycloalkyl polycyclic structures are exemplified and named below: Dicyclohexyl and->Dicyclohexyl group.
"heterocycle", "heterocycloalkyl", "heterocycloalkane" as used herein refers to a saturated or non-aromatic unsaturated ring containing at least one heteroatom; wherein the hetero atom means a nitrogen atom, an oxygen atom, a sulfur atom, etc. Typically a monovalent saturated or partially unsaturated mono-or bicyclic ring system representing a plurality of ring atoms, comprising 1, 2 or 3 ring heteroatoms selected from N, O and S, the remaining ring atoms being carbon. Bicyclic means consisting of two rings sharing two ring atoms, i.e. the bridge separating the two rings is a single bond or a chain of one or two ring atoms. Examples of monocyclic saturated heterocycloalkyl are oxetanyl, azetidinyl, pyrrolidinyl, 2-oxo-pyrrolidin-3-yl, tetrahydrofuranyl, tetrahydro-thienyl, pyrazolidinyl, imidazolidinyl, thiazolidinyl, piperidinyl, tetrahydropyranyl, tetrahydrothiopyranyl, piperazinyl, morpholinyl,thiomorpholinyl, 1-dioxo-thiomorpholin-4-yl, azepanyl, diazepayl, homopiperazinyl or oxaazepanyl.

Examples of partially unsaturated heterocycloalkyl groups are dihydrofuryl, imidazolinyl, tetrahydro-pyridyl or dihydropyranyl.
As used herein, "aromatic ring" refers to an aromatic hydrocarbon group having multiple carbon atoms. Aryl is typically a monocyclic, bicyclic or tricyclic aryl group having multiple carbon atoms. Furthermore, the term "aryl" as used herein refers to an aromatic substituent that may be a single aromatic ring or multiple aromatic rings fused together. Non-limiting examples include phenyl, naphthyl, or tetrahydronaphthyl.
