Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of pharmaceutical chemistry, and particularly relates to a clarithromycin derivative, a pharmaceutical composition and their applications. Background Art
[0002] Macrolide-lincosamide-streptogramin B (MLS B ) has the same ribosomal binding site A2058 and has cross-resistance. Among them, the 14-membered macrolide antibiotic - erythromycin is a very important therapeutic drug for treating upper and lower respiratory tract infections. The main mechanism of action is that its 5-position deoxysugar amine acts on the ribosomal bases A2058 / A2059 (E. coli numbering) in the form of hydrogen bonds. The second-generation erythromycins - clarithromycin and azithromycin, which emerged in the 1980s, are widely used in the treatment of bacterial pneumonia, mycoplasma pneumonia, etc. They have the advantages of high acid resistance (gastric) and good pharmacokinetic properties, but they have no activity against bacteria and mycoplasmas resistant to erythromycin. [[ID=,12]]
[0003] The drug resistance mechanism of bacteria is that strains containing the erm gene express methylase, resulting in N6 methylation of A2058, leading to a sharp decline in the affinity of erythromycin drugs. As the third-generation erythromycin, ketolide macrolides with a structural feature of removing cladinose at the 3-position and modifying it into a carbonyl group emerged. The representative marketed drug is telithromycin. The aryl group at the end of its 11-position side chain acts on the new sites A752 and U2609 (E. coli numbering) of the bacterial ribosome, and has good antibacterial activity against drug-resistant Streptococcus pneumoniae and Streptococcus pyogenes. It is the only erythromycin derivative approved for marketing to treat community-acquired bacterial pneumonia infections so far. Although telithromycin has activity against sensitive Mycoplasma pneumoniae, it has no activity against Mycoplasma with mutations in A2058 or A2059 (E. coli numbering) (minimum inhibitory concentration MIC = 256 μg / mL), which shows the particularity of drug-resistant mycoplasmas.
[0004] Mycoplasmas are a class of minimal prokaryotic microorganisms that lack cell walls, are highly pleomorphic, can pass through bacteria filters, and can be cultured and multiplied in artificial culture media. Mycoplasma pneumoniae is the pathogen that causes mycoplasma pneumonia, and can also cause upper respiratory tract infections and chronic bronchitis. It is primarily transmitted through the respiratory tract and can occur year-round. For example, in 2023, China experienced an outbreak of drug-resistant mycoplasma pneumoniae infections that lasted for six months. Mycoplasma resistance occurs through mutations of ribosomal bases A2058 / A2059 (Escherichia coli numbering) to G2058 / G2059 / T2058, among others. Currently, the G2058 mutation is the most common mycoplasma found in clinical practice. Currently, new-generation macrolides, including telithromycin, are primarily screened based on their minimum inhibitory concentration (MIC) against resistant bacteria, and activity against mycoplasmas with A2058 or A2059 (E. coli numbering) mutations is rarely tested. Because mycoplasmas and bacteria have distinct resistance mechanisms to macrolides and belong to different species, it is impossible to predict whether a drug will have activity against resistant mycoplasmas based solely on data from anti-resistant bacteria unless there is clear data to support this. Telithromycin, a marketed macrolide with excellent activity against resistant bacteria, is a prime counterexample. It is only active against susceptible Mycoplasma pneumoniae and has no activity against the major clinically resistant mycoplasmas.
[0005] The current structural characteristics of the modification of 3-position non-ketolide are that the 3-position modification is mostly connected to a side chain pharmacophore through an ester group. The ester group is a very unstable group that is easily metabolized and hydrolyzed, thereby losing its activity.
[0006] Therefore, what needs to be solved is to find a new broad-spectrum macrolide antibiotic with pharmacokinetic and stable structural characteristics for clinical use in the treatment of infections caused by pathogenic microorganisms such as erythromycin-resistant Streptococcus pneumoniae, Streptococcus pyogenes, and drug-resistant mycoplasma.

[0024]
[0025]
[0026] In the second aspect of the embodiments of the present invention, a clarithromycin derivative pharmaceutical composition is provided. The clarithromycin derivative pharmaceutical composition includes at least one of the clarithromycin derivatives described in any item of the first aspect, its isotope-labeled substance, solvate, polymorph, pharmaceutically acceptable salt, or its prodrug compound.
[0027] In the third aspect of the embodiments of the present invention, there is provided an application of a clarithromycin derivative described in any item of the first aspect, or the clarithromycin derivative pharmaceutical composition described in the second aspect in the preparation of antibacterial drugs and anti-drug-resistant mycoplasma drugs.
[0028] The present invention has the following advantages:
[0029] 1. Macrolide antibiotics have inhibitory activity against sensitive bacteria and sensitive mycoplasmas. The screening of new macrolide antibiotics represented by telithromycin is basically carried out by testing the activity against drug-resistant bacteria. Through structure-activity relationship research and repeated iterative screening, preferred compounds with high activity against drug-resistant bacteria are obtained; however, compounds with high anti-drug-resistant bacterial activity do not necessarily have high activity against drug-resistant Mycoplasma pneumoniae. The reason is that different species have different numbers of operons. In bacteria with multiple operons, the drug resistance mechanism is the methylation of A2058 catalyzed by erm-mediated erythromycin methylase, while in mycoplasmas with a single operon, it is the mutation of the A2058 base. The former has less impact on the decrease in affinity than the mutation of A2058 to G in mycoplasmas. Therefore, the preferred compounds obtained from antibacterial activity screening have no necessary guiding significance and predictability for improving the activity against drug-resistant Mycoplasma pneumoniae, such as the counterexample - telithromycin. Therefore, the design and screening of compounds against drug-resistant Mycoplasma pneumoniae need to be carried out by analyzing the structure-activity relationship through testing the activity against drug-resistant Mycoplasma pneumoniae. The compounds in the present invention are obtained through structure-activity relationship analysis by testing the activity against drug-resistant Mycoplasma pneumoniae and further testing and screening to obtain compounds that can resist drug-resistant Mycoplasma pneumoniae.
[0030] 2. The preferred compounds obtained after the anti-resistant Mycoplasma pneumoniae activity test screening of the compounds of the present invention also have good antibacterial activity against drug-resistant bacteria in the antibacterial spectrum of erythromycin, and the antibacterial activity is better than that of the second-generation macrolide clarithromycin.
[0031] 3. The compounds of the present invention are connected with side chains through carbamate at the 3-position. Compared with the compounds with ester side chains, they are easily metabolized and hydrolyzed by esterase, and the compounds of the present invention have high stability.

[0057] To enable those skilled in the art to further understand the technical solutions of the present invention, the following further illustrates a clarithromycin derivative, a pharmaceutical composition and their applications provided by the present invention in a specific embodiment manner.
[0058] The following is a brief description of the synthesis method of the clarithromycin derivative of the present invention. In the synthesis examples listed below, the synthesis of intermediates mainly involves Sonogashira reaction, substitution reaction, nucleophilic addition-elimination reaction, etc. Since the clarithromycin derivative prepared by the present invention is a double-side chain derivative obtained by introducing double side chains at the 9th or 11th position and the 3rd position, after the 9th position reacts with an aryl group through the Sonogashira reaction to obtain a compound with an aryl group introduced at the 9th position, when the hydroxyl group at the 3rd position reacts with carbonyldiimidazole, some active groups such as amide groups on the aryl group at the 9th position will react with carbonyldiimidazole to produce side reactions, resulting in by-products with substituents on the aryl group at the 9th position and double modification of the imidazole carbonyl group at the 3rd position, which is not conducive to the purification of the product and the synthesis of the final product.
[0059] Therefore, in order to avoid the above situation, when synthesizing the double-side chain compound at the 9th and 3rd positions, first react the hydroxyl group at the 3rd position with carbonyldiimidazole, and then introduce aryl modification at the 9th position. Further, the side chain and aryl group are introduced at the 3rd position through stepwise reactions. By the above synthesis method, the generation of by-products on the aryl group at the 9th position can be avoided. When synthesizing the double-side chain compound at the 11th and 3rd positions, after introducing the telithromycin side chain at the 11th position, the hydroxyl group at the 3rd position reacts with carbonyldiimidazole to introduce an imidazole carbonyl group. Further, the side chain and aryl group are introduced at the 3rd position through stepwise reactions. By connecting different quinolone side chains at the 3rd position through carbamate, a clarithromycin derivative more stable than the side chain connected by an ester group is obtained.
[0060] Specifically, the following gives the synthesis methods of representative specific compounds of the present invention.

[0396] Resuscitate the cryopreserved strains ATCC29342 (sensitive strain), W-003-1 (mutation of base A2063 in 23S rDNA ribosome to G, corresponding to A2058G in E. coli 23S rRNA), W-034-1 (mutation of base A2063 in 23S rDNA ribosome to T, corresponding to A2058T in E. coli 23S rRNA), BCH-388 (mutation of base A2064 in 23S rDNA ribosome to G, corresponding to A2059G in E. coli 23S rRNA) with known CFU, and dilute them to a final concentration of 10 4 ~10 5 CFU / mL with a liquid medium (without antibiotics and thallium salts), place them at 37 °C for 2 hours to restore vitality, and prepare the stock solution of the test drug to 2048 μg / mL with DMSO.

[0400]
[0401] Among them, the structural formulas of compounds MCX-91 and LXM-17 are shown as follows:
[0402]
[0403] As can be seen from Table 1, the compounds prepared in the present invention all have good anti-mycoplasma activity against drug-resistant mycoplasma. Compared with the second-generation and third-generation erythromycins, the antibacterial activity of the compounds in the examples of the present invention is better because the compounds prepared in the present invention introduce double side chains at the 9th and 3rd positions or the 11th, 12th and 3rd positions, and the 3rd position is connected to different quinolone side chains through carbamate. The crystal structure of the complex of compound 6eA in the examples of the present invention and the ribosome of T. thermophilus shows that the aryl groups of the double side chains of the compounds in the examples of the present invention form a ternary stacking interaction mode with the bases C1782-C2586 in the ribosome, making the compounds in the examples of the present invention bind stronger to the ribosome, and thus having better anti-drug-resistant bacteria and anti-drug-resistant mycoplasma activity.
[0404] Mycoplasma pneumoniae has only one set of rRNA operons, so it is easy to produce base mutations and then develop drug resistance, which is different from the drug resistance mode mediated by the erm resistance gene through methylation of ribosomal A2058 (E. coli number). Although telithromycin has antibacterial activity in erm-mediated drug-resistant bacteria (as shown in Tables 2 and 3), it has no activity against drug-resistant mycoplasma caused by base mutations at A2058 (E. coli number) (as shown in Table 1). In addition, compounds MCX-91 and LXM-17 have good antibacterial activity against drug-resistant bacteria, but have poor activity against drug-resistant Mycoplasma pneumoniae. Therefore, compounds developed using the antibacterial activity structure-activity relationship do not necessarily have anti-drug-resistant mycoplasma activity, and the preferred compounds screened from antibacterial activity have no necessary guiding significance and predictability for improving the activity against drug-resistant Mycoplasma pneumoniae in bacteria, and new macrolide compounds need to be developed specifically based on the anti-mycoplasma structure-activity relationship. The compounds in the present invention are obtained by analyzing the structure-activity relationship through testing the activity against drug-resistant Mycoplasma pneumoniae and further testing and screening to obtain compounds capable of resisting drug-resistant Mycoplasma pneumoniae.
[0405] Example 57: Antibacterial Activity Test
[0406] According to the standards recommended by the Clinical and Laboratory Standards Institute (CLSI, 2010), the in vitro antibacterial activities of some target compounds against sensitive Streptococcus pneumoniae ATCC49619, mef-type resistant Streptococcus pneumoniae PU-09, constitutive erm-type resistant Streptococcus pneumoniae 07P390, ermA-type resistant Streptococcus pyogenes 12-206, and inducible resistant Streptococcus pyogenes 01-968 were determined by the broth dilution method. Each strain of bacteria was subcultured and purified on a plate before the experiment, and fresh bacterial cells were used for the experiment. In each experiment, a standard strain was used as the quality control bacterium for the sensitivity test; a bacterial solution without antibacterial drugs was used as the growth control for the test strains. The minimum inhibitory concentration (MIC) was determined by the broth two-fold dilution method. The concentration range of the antibacterial drugs tested was 256 - 0.008 μg / mL, and the final concentration of the test bacterial solution was approximately 5×10 5 CFU / mL.

[0410]
[0411]
[0412] The compounds of the present invention not only have good activities against drug-resistant Mycoplasma pneumoniae, but also have better antibacterial activities against drug-resistant bacteria in the antibacterial spectrum of erythromycin (see Tables 2 - 3) as tested.
[0413] Example 58: Metabolic stability test of compound 12eD with MCX-66 liver microsomes
[0414] Determine the intrinsic clearance (CL) of the compound in rat liver microsomes int(liver))。Incubate 0.1 M potassium phosphate buffer (pH 7.4) containing 0.5 mg microsomal protein with cofactor (NADPH) at 37 °C for 5 minutes. Then add the test compound (1.0 μm) to the incubation solution, and continue to incubate the mixture at 37 °C. At 0, 10, 20, 30, 45, and 60 minutes respectively, take 100 μL of the incubation mixture and add it to 300 μL of acetonitrile containing the internal standard solution to terminate the reaction. Analyze the sample by LC-MS / MS (liquid chromatography-tandem mass spectrometry), and calculate the ratio of the peak area of the compound to the peak area of the internal standard in the positive ion mode. The intrinsic clearance rate is determined by the first-order elimination constant through non-linear regression, and the incubation volume is corrected, assuming that the microsomal protein content is 45 mg / g liver and the liver weight-body weight ratio of rats is 40 g / kg. The value of CL int(liver) is expressed as ml / min / kg liver. In the experiment, 7-ethoxycoumarin was used as the control group for detection. Among them, compound MCX-66 is a similar compound of compound 12eD, and its side chain group is connected through an ester group at the 3-position. The specific structure is as follows:
[0415]
[0416] Table 4 Liver microsomal metabolism results of compound 12eD and MCX-66
[0417]
[0418]
[0419] In Table 4 a CL int(liver) : Intrinsic clearance rate CL int(liver) : 0.693 / T 1 / 2 / mg amount of microsomal protein per ml of liver microsomal solution × mg microsomal protein / g liver weight × g liver weight / kg body weight.
[0420] Compound 12eD in the examples of the present invention has a longer half-life in the liver microsomes of rats than the analogue MCX-66. The ester side chain (analogue MCX-66) is more easily hydrolyzed and metabolized by esterase compared to the 3-carbamate side chain (compound 12eD). Therefore, the 3-carbamate side chain (compound 12eD) in the macrolide has higher pharmacokinetic stability than the 3-ester side chain (analogue MCX-66). Since the compounds in the examples of the present invention all have side chain groups connected by carbamate at the 3-position, the clarithromycin derivatives prepared in the examples of the present invention are more stable than the similar compounds connected by ester side chains.
