Description

[Technical Field]

[0001] This invention relates to a tetracyclic aromatic amide derivative, its preparation method, pharmaceutical compositions containing the derivative, and its use as a therapeutic agent, particularly as a DHX9 inhibitor. [Previous Technology]

[0002] DExH-box helicase 9 (DHX9) is a member of the DExD / H-box helicase family. It is an NTP-dependent helicase protein that can unwind RNA, DNA, and aberrant polynucleotide structures, and is therefore also known as nuclear DNA helicase II (NDH II) and RNA helicase A (RHA). The core domain of this family of helicases has a conserved Asp-Glu-Ile-His (DEIH) sequence, which is the core region for NTP binding and hydrolysis.

[0003] Because DHX9 lacks alkali selectivity, it can utilize all four NTPs to meet its energy requirements. It is a multi-domain, multifunctional protein that plays an important role in biological development, DNA replication, transcription, translation, repair, splicing, editing, RNA processing, transport, remodeling, and maintaining genome stability.

[0004] Due to its regulatory role in processes such as transcription and maintaining genome stability, DHX9 has been shown to be a key regulatory factor in various cancer types, participating in the regulation of genes associated with sustained proliferation signaling, evasion of growth inhibitors, evasion of apoptosis, angiogenesis, and metastasis—all of which are hallmarks of cancer. Specifically, microsatellite instability cancers, such as microsatellite instability (MSI) colorectal cancer, and tumors with defective mismatch repair (MMR), exhibit a strong dependence on DHX9.

[0005] In addition to its role in cancer, DHX9 is also associated with other diseases involving gene replication, translation, or regulation. These diseases include viral infections and autoimmune diseases.

[0006] There are no new drugs targeting DHX9 on the market, nor is there any information on clinical compounds. As a novel anti-tumor target, DHX9 has enormous potential for research, and it is essential to develop inhibitors targeting this target. [Summary of the Invention]

[0065] A "leaving group" is an atom or functional group that breaks off from a larger molecule in a chemical reaction. It is a term used in nucleophilic substitution and elimination reactions. In a nucleophilic substitution reaction, the reactant attacked by the nucleophile is called the substrate, and the atom or group of atoms that breaks off from the substrate molecule carrying a pair of electrons is called the leaving group. Groups that readily accept electrons and have a strong ability to accept negative charges are good leaving groups. The smaller the pKa of the conjugate acid of the leaving group, the easier it is for the leaving group to break off from other molecules. This is because when the pKa of its conjugate acid is smaller, the corresponding leaving group does not need to combine with other atoms, and the tendency to exist in the form of anion (or electrically neutral leaving group) is enhanced. Common leaving groups include, but are not limited to, halogens, methanesulfonyl, -OTs, or -OH.

[0066] "Substituted" refers to one or more hydrogen atoms in a group, preferably up to five, more preferably one to three hydrogen atoms, which are independently substituted by the corresponding number of substituents.

For example, an amino or hydroxyl group with free hydrogen may be unstable when combined with a carbon atom having an unsaturated bond (such as an alkene).
