Description

Technical Field

[0001] The invention belongs to the field of chemical synthesis, relates to quinazolinone enone azole compounds, and also relates to a preparation method and application of the compounds. Background Art

[0002] Pathogen infections threaten human health, and antibiotics have always been the main treatment for pathogenic microbial infections. However, over the past few decades, excessive and inappropriate exposure to antibiotics has led to the offset of bacterial antibiotic pressure and the development of drug resistance, making the effectiveness of clinical drugs increasingly limited. A global survey showed that 4.95 million people died from diseases caused by bacterial antimicrobial resistance (AMR) in 2019, which means that the number of deaths caused by drug resistance exceeded that of HIV / AIDS or malaria. In addition, a large amount of literature shows that current drugs with a single target are easily inactivated against multidrug-resistant pathogens due to target failure caused by bacterial gene mutations. There is no doubt that there is an urgent need to identify new antibacterial drugs with novel structures and multiple targets to deal with infections from multidrug-resistant bacteria.

[0003] Quinazolinone alkaloids, as the core structure of traditional Chinese medicine ingredients such as febrifugine, evodiamine and tryptamine, have great potential for biological activity. Quinazolinone has a unique structural feature of the benzopyrimidinone skeleton and is considered to be an important new antimicrobial chemical structural framework. The synthesis, structural modification and biomedical potential of its derivatives have naturally attracted great attention. In particular, quinazolinone has a structure similar to the widely used clinical antibacterial drug quinolone and has been widely studied in the antimicrobial field. The combination of quinazolinone and many azoles such as thiazole, oxadiazole, pyrazole and imidazole shows excellent antibacterial activity. Therefore, the combination of quinazolinone and azole compounds has infinite potential in the antibacterial field.

[0004] As nitrogen-containing heterocyclic compounds with electron-rich aromatic structures, azole compounds have received extensive attention in drug design and development, and have been widely used in agrochemicals, medicine and other fields. The unique structure of azole compounds makes it easy for them to bind to multiple targets in organisms through a variety of weak interactions such as hydrogen bonds, coordination, ion dipole, hydrophobic interaction, van der Waals force, etc., and show significant biological activity.

[0005] As an important class of structures, ethylene ketones have the excellent characteristics of easy synthesis and multiple modification sites. In addition, ethylene ketones can not only act as bridging groups to promote the increase of conjugated systems, thereby inserting DNA to prevent bacterial DNA replication, but also regulate biological activity by attaching different aromatic rings on both sides of ethylene ketones. Therefore, ethylene ketone fragments with this unique polar functional group are widely used as a framework for drug design. A large number of literature studies have shown that ethylene ketones in some conjugates play an important role in the activity of the molecule, and the biological activity will disappear if the ethylene ketone group is removed. .

[0006] Based on our work in the field of quinazolinone and azole antimicrobial drugs, we inserted ethylene ketone between quinazolinone and azole to construct quinazolinone enone azole structural compounds, hoping to develop new antibacterial molecules to solve the increasingly serious global problem of drug resistance.
