Abstract

The invention provides a novel quinoline derivative inhibitor, in particular to a quinoline derivative of a TAM family kinase inhibitor, which has a structure shown in the following general formula (I).

Description

Quinoline derivatives of TAM family kinase inhibitors
Technical Field
The invention belongs to the field of medicines, and particularly relates to a TAM family kinase inhibitor compound represented by a general formula (I), pharmaceutically acceptable salts, esters, stereoisomers and tautomers thereof, and a pharmaceutical composition, a pharmaceutical preparation and application thereof. The compound can selectively inhibit the TAM family of tyrosine kinases, and can be used for treating and/or preventing diseases mediated by abnormal expression of the TAM family kinases/receptors and/or ligands thereof
Background
The TAM family includes 3 members of Axl, Mer, Tyro-3, which contains the extracellular domain, the transmembrane domain, and the conserved intracellular kinase domain. Wherein the extracellular domain consists of two immunoglobulin-like domains connecting two type III fibronectin repeat units. The conserved amino acid sequence KW (I/L) A (I/L) ES of the intracellular kinase domain is a unique structural feature of the TAM family. This family has 1 common ligand, growth inhibitory specific protein 6(Gas6), which binds to all TAM receptors, but differs in strength. Besides TAM family, there are vitamin K dependent protein S (ProS), short crude-like protein Tubby, recombinant human short crude-like protein 1(Tulp1), galactose lectin-3 (galectin-3) and other related receptors (Wuyangjun, J.Xinyao, 2016; Lemna, J.practical diagnosis and treatment, 2016).
Among them, Axl (named UFO, Ark, Tyro-7, JTK1, respectively), Mer (named c-Mer, Mertk, Eyk, Nyk, Tyro-12, respectively), Tyro-3 (named Sky, Byk, Rse, Dtk, etc.), galectin-3, Gas6, and ProS are abnormally expressed in various solid tumors such as lung cancer, stomach cancer, and liver cancer, and various hematological tumors such as AML, ALL, and CML, and have strong correlation with poor prognosis of disease, disease progression, tumor metastasis, and tumor resistance (Douglas K, Nature reviews, 2014). Particularly, Axl, a tyrosine kinase, has been shown to be one of the causes of EGFR inhibitor resistance in NSCLC and is closely related to the metastasis of various solid tumors. The drug developed with this as a target also demonstrated the effect of inhibiting Axl in delaying drug resistance and tumor metastasis of EGFR inhibitors (T. Jimbo, Annals of Oncology, 2017; Sacha J. Holland, American Association for Cancer Research, 2010). At the same time, Axl, Mer, Tryo-3 and TAM ligands also play a significant role in the direction of immune tumors. Inhibition of the TAM family and its ligands can reverse the immunosuppressive environment of tumors, enhance the ability of the immune system to kill tumor cells, by promoting the polarization of macrophages to M1-type macrophages, increasing the activation and function of effector T cells, enhancing the anti-tumor activity of NK cells, and the like (yemsrat T. akalu, Immunological Reviews, 2017; Greg Lemke, Nature Reviews Immunology, 2008). Therefore, the development of the inhibitor can have strong inhibition and treatment effects on various solid and blood tumors induced by the family, such as lung cancer, liver cancer, breast cancer, brain glioma, melanoma, AML, ALL, CML and the like.
In addition to the above-mentioned tumor diseases, TAM family receptors and ligands can regulate various physiological functions such as vascular smooth muscle homeostasis, platelet aggregation, thrombus stabilization, erythropoiesis, oligodendrocyte survival, osteoclast function, apoptotic cell phagocytosis, inflammation, innate immunity, and the like. Therefore, the TAM family inhibitor can also be used for treating endometriosis, vascular diseases/injuries, psoriasis, visual defects/pathological changes (caused by macular degeneration, diabetes, premature birth and the like), kidney diseases, rheumatoid arthritis, osteoporosis and other related diseases caused by the disturbance of TAM family signal pathways.

In the context of the present invention, unless otherwise explicitly defined, or the meaning is beyond the understanding of those skilled in the art, hydrocarbons or hydrocarbon-derived groups of 3 or more carbon atoms (such as propyl, propoxy, butyl, butane, butene, butenyl, hexane, and the like) all have the same meaning when not preceded by the word "n". For example, propyl is generally understood to be n-propyl, and butyl is generally understood to be n-butyl, unless otherwise specified.
All publications, patent applications, patents, and other references mentioned in this specification are herein incorporated by reference in their entirety. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. In case of conflict, the present specification, including definitions, will control.
In the context of this specification, anything or things not mentioned is directly applicable to the art-known technology without any change except where explicitly stated. Moreover, any embodiment described herein may be freely combined with one or more other embodiments described herein, and the technical solutions or concepts resulting therefrom are considered part of the original disclosure or original disclosure of the invention, and should not be considered as new matters not disclosed or contemplated herein, unless a person skilled in the art would consider such a combination to be clearly unreasonable.
In the present invention, "C a-b The expression "radicals" (a and b denote integers of 1 or more, a < b) denotes the presence of a-b carbon atoms in the "radical", e.g. C 1-4 Alkyl, i.e. alkyl having 1-4 carbon atoms, C 1-4 Alkoxy, i.e. alkoxy having 1 to 4 carbon atoms, C 3-10 Cycloalkyl, i.e. a cycloalkyl group having 3 to 10 carbon atoms, C 1-4 Alkoxy radical C 1-4 The alkyl group means a group in which an alkoxy group having 1 to 4 carbon atoms is bonded to an alkyl group having 1 to 4 carbon atoms.
In the present invention, "group" and "group" represent a monovalent group or a divalent or more group in accordance with the valence as required, and for example, "cycloalkyl group (also expressed as cycloalkyl group)" includes a monovalent group obtained by removing one hydrogen atom therefrom, and also includes a divalent or more group obtained by removing two or more hydrogen atoms from the same carbon atom or two or more different carbon atoms therein. "cycloalkyl" is naturally a monovalent group when it is a terminal group, and is a divalent or higher group when it is a linking group in the structure. In the present invention, a monovalent or divalent or higher group generally means a monovalent group or a divalent group, but the group may be higher in valence (for example, trivalent, tetravalent, pentavalent, hexavalent, etc.) as required. The person skilled in the art can unambiguously determine the number of valences represented by the "radical" and "radical". The group "derived by removing one or more hydrogen atoms" as used herein means a monovalent group obtained by removing one hydrogen atom, a divalent group obtained by removing two hydrogen atoms, a trivalent group obtained by removing three hydrogen atoms, a tetravalent group obtained by removing four hydrogen atoms, and the like, and the number of hydrogen atoms to be removed can be determined according to the valency (for example, 1,2,3, 4, and the like) of the group.
The "halogen atom" as referred to herein means a fluorine atom, a chlorine atom, a bromine atom, an iodine atom. Preferably a fluorine atom, a chlorine atom, or a bromine atom.
As used herein, "halo" means that any carbon atom in a substituent has one or more hydrogens of the same or different halogen atoms replaced. The "halogen atom" is as defined above.
"C" according to the invention 1-6 Alkyl "refers to a straight or branched chain alkyl group derived from an alkane moiety containing 1 to 6 carbon atoms by the removal of one or more hydrogen atoms, including straight chain C 1-6 Alkyl and branched C 1-6 An alkyl group. In fact, C is well known to those skilled in the art 1-6 The alkyl group having a branch (branch C) 1-6 Alkyl) having at least 3 carbon atoms.
