Description
Technical Field
The invention belongs to the field of chemical medicines, and particularly relates to a quinolinone derivative, a preparation method and application thereof.
Background
Tuberculosis is a chronic infectious disease caused by mycobacterium tuberculosis infection, and is one of ten global fatal diseases. Wherein one-fourth of tuberculosis deaths are caused by drug resistant tuberculosis. To date, the treatment of drug-sensitive tuberculosis has remained along with four drugs in the 70 s of the last century: isoniazid, rifampicin, pyrazinamide and ethambutol. The approval of bedaquiline and delaimab for sale by FDA and EMA in europe has been made in the united states since 2012, but currently being controversial, and not yet used as first-line antitubercular drugs due to the undefined toxic response and efficacy of bedaquiline and delaimab. Therefore, the development of anti-mycobacterium tuberculosis drugs having novel chemical structures and modes of action is considered as an important research direction at present.
Mycobacterium tuberculosis has a characteristic, complex cell wall structure, and involves a variety of functions related to cell physiology and pathogenesis. Whereas the unique DprE1 key enzyme within mycobacteria is associated with mycobacterium tuberculosis cell wall biosynthesis, it is critical for mycobacterium tuberculosis survival. The inhibitors of the DprE1 enzyme found in the past few years (e.g., BTZ and OPC-167832) have been found to be able to cause mycobacterial death by covalent or non-covalent binding to the DprE1 enzyme. These compounds all show antitubercular efficacy, providing strong evidence for the design of DprE1 enzyme inhibitors and treatment of tuberculosis.
However, the properties such as antitubercular activity of the existing DprE1 enzyme inhibitor still need to be further improved, and further research on quinolinone compounds with controllable toxicity, better antitubercular activity, better pharmacokinetic properties and better application prospects is expected to obtain better clinical treatment effects, so that the quinolinone compounds have important significance.

Detailed Description
The raw materials and equipment used in the invention are all known products and are obtained by purchasing commercial products.
Example 1,
Compound A1 5- ((1- (4-chloro-2, 6-difluorophenyl) -4-hydroxypiperidin-4-yl) methoxy) -3, 4-dihydroquinolin-2 (1H) -one
The synthetic route for compound A1 is as follows:
the first step:
250mL of dry tetrahydrofuran was added to a three-necked flask, and raw material 1 (28.23 g,200 mmol) and raw material 2 (35.56 g,240 mmol) were dissolved therein, and the mixed system was cooled to 0℃with an ice-salt bath. 110mL of a sodium hexamethyldisilazide solution having a concentration of 2mol/L was slowly dropped into the constant pressure dropping funnel. The reaction was exothermic and the dropping rate was controlled to maintain the reaction temperature at 0-2 ℃. After the dripping is finished, the reaction mixture is kept at 0 ℃ and stirred for 10min, then the ice salt bath is removed, the temperature of the ice salt bath is naturally raised to room temperature, and the reaction mixture is stirred at the room temperature for 3h. TLC monitored the completion of the reaction, the reaction was swirled under reduced pressure to remove most of the solvent, ice water was added to the obtained residue, saturated aqueous citric acid solution was slowly added to carefully adjust the system to neutrality, and after three extractions with dichloromethane were performed, the organic phases were combined and washed with water and saturated brine in this order. The organic phase was separated and dried over anhydrous sodium sulfate, suction filtered and spin-dried, and purified by column chromatography to give the target intermediate 3.2g (yield 84%) as a pale yellow oil.
And a second step of:
into a two-necked flask, 135mL of concentrated sulfuric acid was added, and the sulfuric acid was cooled to 0℃with an ice-salt bath. Intermediate 3 (43.0 g,167 mmol) was dissolved in 40mL of methylene chloride, the resulting solution was slowly added dropwise to the above sulfuric acid solution via a dropping funnel over a period of 30min, and the dropping speed was controlled so that the reaction solution temperature was maintained at 0-5 ℃. After the dripping is finished, the reaction mixture is kept at 0 ℃ and stirred for 10min, then the ice salt bath is removed, the temperature of the ice salt bath is naturally raised to room temperature, and the reaction mixture is stirred at the room temperature for 2h. TLC monitored the completion of the reaction, the reaction was swirled off the vast majority of the low boiling solvent dichloromethane at 30 ℃ under reduced pressure, and the resulting residue was added to crushed ice. The mixture was stirred, the solid was allowed to precipitate in a large amount, the precipitate was allowed to stand for 20min, and the solid was filtered off with a separator funnel. The solids were transferred to a beaker and washed thoroughly with water, and the filter cake was brought to near pale yellow to off-white when the filtrate pH was near 7. The cake was taken out and dried in a vacuum oven with phosphorus pentoxide to give 28.7g (yield: 89%) of intermediate 4 as a pale yellow solid.
And a third step of:
intermediate 4.0 g was dissolved in 100mL of glacial acetic acid, and 4.6g of 10% palladium on carbon was added thereto after stirring and dissolution. After 5 times of nitrogen substitution, hydrogen substitution is carried out again, and the mixture is heated to 110 ℃ in a hydrogen atmosphere to react for 3d. After the TLC detection reaction is finished, the acetic acid solvent is distilled off under reduced pressure, the reaction system is diluted by PE: EA=2:1, diatomite is used for suction filtration, and sodium bicarbonate or sodium carbonate aqueous solution is added after the filtrate is dried in a spinning way to adjust the pH of the system to be about 7. The mixture is sonicated for 10min, the filter cake is filtered off with suction and washed with water several times. The filter cake was filtered off with suction and dried, and then rinsed several times with DCM to give a filtrate. The filtrate was dried by spin-drying and separated by silica gel column chromatography to give intermediate 5.6 g, yield 92.9%.
Fourth step:
21.0g of intermediate 5 was weighed, dissolved in 300mL of dry dichloromethane, cooled to-15℃in a cold bath at-30℃and 400mL of BBr was slowly added dropwise under these conditions 3 . The dropping speed is controlled to keep the system temperature below-10 ℃. After the addition, the stirring is carried out for 30min at low temperature, the cold bath is removed, the reaction system is naturally warmed to room temperature, and the stirring is carried out for 3h. TLC monitoring showed complete reaction, the system was spun down at room temperature under reduced pressure to remove solvent and low boilers, the residue was added to 200mL of crushed ice and stirred until the crushed ice was completely dissolved. Dichloromethane was added for extraction and the solution was separated. The aqueous phase was extracted three more times with dichloromethane and the organic phases were combined and washed with water, saturated brine. The organic phase was separated and dried over anhydrous sodium sulfate, suction filtered and spin-dried to give a filtrate, which was purified by column chromatography to give 6.2g of a white solid intermediate in 83% yield.
Fifth step:
intermediate 6 (100 mg,0.55 mmol) was dissolved in 6mL anhydrous DMF, anhydrous potassium carbonate (114 mg, 0.8235 mmol) was added, and after stirring at room temperature for 5min, raw material 7 (171 mg,0.66 mmol) was slowly added and the temperature was raised to 80℃for reaction for 6h.
