Description

Tricyclic fused heterocyclic compound, preparation method and application thereof in medicine

Technical Field

The present disclosure belongs to the field of medicine, and relates to tricyclic fused heterocyclic compounds, a preparation method thereof and application thereof in medicine. In particular, the present disclosure relates to tricyclic fused heterocyclic compounds of general formula (I), methods for their preparation, pharmaceutical compositions containing them and their use as AhR modulators, particularly in the manufacture of a medicament for the treatment and/or prophylaxis of AhR protein mediated diseases or conditions.

Background

The Aromatic Hydrocarbon Receptor (AHR), also known as the dioxin receptor, is a member of the family of transcription regulators bHLH (basic Helix-Loop-Helix) -PAS (Per-ARNT-Sim). The unique feature of the bHLH-PAS family member is the PAS domain, the name of which originates from the three proteins that were first found to have this motif: drosophila Per, human ARNT and Drosophila Sim. The PAS domain consists of 260-310 amino acids and comprises two very conserved hydrophobic repeats, designated PAS-A and PAS-B, separated by se:Sup>A less conserved sequence. The bHH domain is responsible for binding to DNA, and tandem PAS domains (PAS-se:Sup>A and PAS-B) are involved in protein-protein interactions and ligand binding. In AHR, ligand binding occurs in the PAS-B domain. The N-terminal bHLH-PAS region of the bHLH-PAS family member is better conserved. Most non-conservative changes in AHR occur in the transcriptional activation domain, resulting in different protein-protein interactions with other co-activators, co-inhibitors, or nuclear receptors, regulating different gene expression.

In the absence of ligand, AHR is present in the cytosol and binds to a variety of chaperones, including a dimeric heat shock protein 90 (heat shock protein, HSP 90), accessory chaperone p23, AHR acting protein (AHR-Interacting Protein, AIP) and protein kinase Src. When bound to a ligand, AHR changes its conformation, translocates to the nucleus, separates from the chaperone complex, and then forms a heterodimer with the AHR nuclear translocator (Aryl hydrocarbon Receptor Nucleus Translocator, ARNT). The regulatory region upstream of the AHR regulatory gene comprises a DNA consensus sequence (5 '-TNGCGTG-3'), termed the foreign response element (Xenobiotic Responsive Element, XRE), also termed the dioxin response element (Dioxin Responsive Element, DRE). It acts as a transcriptional enhancer and is a site of binding to AHR. AHR-ARNT heterodimer complex is recruited by XRE to initiate transcription of the target gene.

Research shows that AHR is involved in physiological processes such as cell physiology, host defense, immune cell proliferation differentiation, detoxification and the like. AHR is expressed in many cells of the immune system, including dendritic cells, macrophages, T cells, NK cells, and the like.

Because the ligand binding site of AHR is structurally flexible, many small molecules can act as ligands, including exogenous ligands such as polycyclic aromatic hydrocarbons, dioxins, polychlorinated biphenyls, and the like; endogenous ligands such as metabolites of tryptophan degradation, food-derived ligands and products of bacterial, microbial metabolic pathways. For example, the AHR modulator, this vitamin, is a naturally-derived small molecule produced by bacterial symbiota of entomopathogenic nematodes, is an aromatic receptor agonist that is first marketed worldwide, and can be used to treat a variety of autoimmune diseases, such as psoriasis, eczema, etc. However, due to the structural characteristics of the present vitamin mod, for example, the phenomenon of unstable light exists, the present vitamin mod is easy to degrade under illumination, and the application of the present vitamin mod is limited. Therefore, the continuous development of AHR modulators with wider clinical application range, low side effects and stability is significant.

Published related patent applications include WO2021066573A1, WO2018068131A1, CN113797159A, CN112811985A, CN111759803B and CN113004127A, among others.

An "arene receptor (AHR) modulator" as described in this disclosure refers to an agent that causes or facilitates a qualitative or quantitative change, alteration or modification of one or more processes, mechanisms, effects, reactions, functions, activities or pathways mediated by the AHR receptor. Such changes mediated by an AHR modulator (an inhibitor of AHR or a non-constitutive agonist as described herein) may refer to a decrease or increase in AHR activity or function, such as a decrease, inhibition, or metastasis of AHR constitutive activity.

By "AHR antagonist" is meant an AHR inhibitor that does not itself elicit a biological response when specifically binding to an AHR polypeptide or an AHR-encoding polynucleotide, but blocks or inhibits an agonist-mediated or ligand-mediated response, i.e., an AHR antagonist may bind to but does not activate an AHR polypeptide or an AHR-encoding polynucleotide, and the binding disrupts interactions, replaces an AHR agonist, and/or inhibits the function of an AHR agonist. Thus, as used herein, when bound to AHR, AHR antagonists do not act as inducers of AHR activity, i.e., they act as pure AHR inhibitors.

As used herein, reference to an "AhR-mediated" disease and/or disorder means any disease or other deleterious condition in which AhR or mutants thereof are known to function. Thus, another embodiment of the invention relates to treating or lessening the severity of one or more diseases for which AhR or mutants thereof are known to play a role.
