Abstract
Description
Tetranuclear aromatic amide derivatives, processes for their preparation and uses thereof TECHNICAL FIELD
[0001] The present application relates to a tetranuclear aromatic amide derivative, a preparation method thereof, a pharmaceutical composition containing the derivative and the use thereof as a therapeutic agent, particularly as a DHX9 inhibitor. BACKGROUND
[0002] DExH-box Helicase 9 (DHX9) belongs to the members of the DExD / H-box family of helicases, and is an NTP-dependent helicase protein that can unwind RNA, DNA and abnormal polynucleotide structures, and is therefore also known as nuclear DNA helicase II (NDH II) and RNA helicase A (RHA). The core domain of the helicase of the family has a conserved Asp-Glu-Ile-His (DEIH) sequence, which is the core region where NTP binding and hydrolysis occur.
[0003] Since DHX9 lacks base selectivity, DHX9 can use all four NTPs to meet its energy needs, and is a multi-domain, multifunctional protein that plays an important role in biological development, DNA replication, transcription, translation, repair, splicing, editing, RNA processing, transport, reconstitution, and maintenance of genomic stability.
[0004] Due to its regulatory role in processes such as transcription and maintenance of genomic stability, DHX9 has been shown to be a key regulator in multiple cancer types, and is involved in the regulation of genes associated with persistent proliferation signaling, evasion of growth suppressors, evasion of apoptosis, angiogenesis and metastasis, all of which are hallmarks of cancer. Specifically, microsatellite unstable cancers, such as microsatellite instability (MSI) colorectal cancer, and tumors with defective mismatch repair (MMR) show 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 is no new drug on the market for inhibitors targeting DHX9, and there is no clinical compound information. As a brand new antitumor target, there is a huge exploration space for the research of DHX9 target, and it is necessary to develop inhibitors targeting the target. SUMMARY

[0090] A "leaving group," or simply a group, is an atom or functional group that breaks off from a larger molecule in a chemical reaction. It's 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 with a pair of electrons from the substrate molecule is called the leaving group. Groups that readily accept electrons and have a strong ability to accept negative charges are desirable 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 a smaller pKa means the leaving group doesn't need to bond with other atoms and has a stronger tendency to exist as an anion (or an electrically neutral leaving group). Common leaving groups include, but are not limited to, halogens, methanesulfonyl groups, -OTs, or -OH.
