Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of chemical synthesis, and particularly relates to an amide compound, a preparation method thereof, and an application thereof. Background Art
[0002] Bacteria play a crucial role in the environment, but at the same time pose a great threat to human life and health. The extensive use of clinical antibiotics now exerts a huge selective pressure on bacteria, inevitably leading to the emergence of drug resistance. The alarming increase in the drug resistance of bacteria to existing clinically used drugs is a serious problem faced by antimicrobial drug selection, and at the same time, the drug resistance of bacteria to existing antibacterial agents has also become one of the main causes of morbidity and mortality worldwide.
[0003] Chinese Patent Application CN114478474A discloses an amide compound and a preparation method thereof. The amide compound has the following structural formula:
[0004]
[0005] wherein R represents one of C1-C 16 alkyl, C6-C 15 aryl, and C4-C7 heterocycle. It has a relatively large binding energy with FabH, can be used as a FabH inhibitor to inhibit the growth of bacteria, and has advantages such as good antibacterial activity, low toxicity, and low hemolysis.
[0006] Amide, as a class of nitrogen-containing carboxylic acid derivatives, specifically refers to a compound formed by the connection of an acyl group and a nitrogen atom. In the medical field, amide derivatives have shown great promise, especially in antibacterial aspects. It can not only effectively inhibit and kill bacteria, but also has excellent anti-tumor and antiviral capabilities. Its antibacterial spectrum is very broad, which means it can fight against many different types of bacteria. More importantly, compared with other antibacterial drugs, amide derivatives have significant advantages, and it is extremely difficult for bacteria to develop drug resistance to them. Therefore, amide derivatives have extremely high application value in the medical antibacterial field, providing a new direction and hope for solving the increasingly serious problem of bacterial drug resistance.
[0007] Therefore, it is of research significance to develop a new-structured amide compound as an antibacterial compound. Summary of the Invention

[0561] Test Example 1
[0562] Antibacterial test:
[0563] The medium required for the strain is Mueller-Hinton medium (MH medium: 17.5 g of casein hydrolysate, 1.5 g of soluble starch, 1000 ml of beef extract).
[0564] The minimum inhibitory concentration (MIC) value of the test compound is determined by the colorimetric method of MTT (3-(4,5-dimethylpyridin-2-yl)-2,5-diphenyl bromide).
[0565] The compound was dissolved in dimethyl sulfoxide (DMSO) to prepare a storage solution with a concentration of 100 μg / mL, and the storage solution was added to a specified volume of sterile liquid MH medium in gradient amounts. A specific volume of the compound solution containing the medium was added to a microtiter plate. A suspension with a bacterial count of approximately 105 cfu / mL was prepared and added dropwise to the microtiter plate, and incubated at 37 °C for 24 h together with the serially diluted compound. After measuring the MIC value of each microtiter plate by microscopy, phosphate buffer solution (PBS; 50 mL, 0.01 M, pH 7.4, 2.9 g Na2HPO4·12H2O, 0.2 g KH2PO4, 8.0 g NaCl, 0.2 g KCl, 1000 ml distilled water) with an MTT concentration of 2 mg / mL was added to each well. It was left at room temperature for 4 - 5 hours, the reaction solution in each well was removed, and 100 mL of isopropanol containing 5% HCl (final concentration of 1 M) was added to extract the dye. After incubation at room temperature for 12 hours, the microplate reader was set to measure the optical density (OD) at 550 nm. The test results are shown in Table 1:
[0566] Table 1. Antibacterial effect
[0567]
[0568]
[0569]
[0570]
[0571] As can be seen from Table 1, most compounds have certain antibacterial abilities against both Gram-positive and Gram-negative bacteria. By introducing different amine compounds, their antibacterial activities were evaluated. Taking kanamycin B as a reference, the inhibitory effects of various amide compounds on two Gram-negative bacteria (Escherichia coli and Pseudomonas fluorescens) and two Gram-positive bacteria (Staphylococcus aureus and Bacillus subtilis) were compared. When the amino group of the amide was modified with a hydrophobic region structure, the lipophilicity and membrane permeability did not significantly improve the antibacterial activity. However, fluorination of the benzene ring significantly improved the antibacterial activity, and the MIC values for the four common bacterial strains were between 12.5 μg / mL and 25 μg / mL, and the antibacterial activity was enhanced. In this regard, the antibacterial performance of derivatives with fluorine substitution at two different positions was also consistent with the previous results. Among halogen substitutions, fluorine-substituted derivatives had better antibacterial activities than the corresponding bromine- and chlorine-substituted derivatives. Derivatives containing a trifluoromethyl substituent had significantly better antibacterial activities than the corresponding derivatives without a substituent at the same position.

Any simple modification or equivalent replacement made by those of ordinary skill in the art to the technical solution of the present invention shall not depart from the essence and scope of the technical solution of the present invention.
