Abstract
Description
Technical Field
[0001] This invention belongs to the field of anti-tuberculosis drug technology, specifically relating to a class of heterocyclic ethylenediazine hexamolybdate tetrabutylammonium derivatives, their preparation methods, and applications. Background Technology
[0002] Tuberculosis (TB) is a chronic infectious disease caused by Mycobacterium tuberculosis. The World Health Organization (WHO) estimates that 7.5 million new TB cases were diagnosed globally in 2022, and approximately 1.3 million people die from the disease each year. Isoniazid (INH), also known as isoniazid, is a heterocyclic hydrazide compound with extremely strong inhibitory activity against Mycobacterium tuberculosis. Since its introduction for TB treatment in the 1950s, isoniazid remains a first-line drug (Lancet 2019, 393, (10181), 1642-1656). Given the increasing resistance of Mycobacterium tuberculosis to currently used anti-TB drugs and the growing number of TB cases globally, there is an urgent need to develop novel anti-TB drugs. A common strategy for developing new drugs is to modify the structure of existing drugs to regulate their performance.
[0003] Polyoxometalates (POMs) are a class of isolated polymetallic anionic oxygen clusters formed by former transition metals and oxygen ligands. These polyoxometalates not only possess diverse structures and rich compositions, but also exhibit biological activities such as antitumor, antibacterial, and antiviral activity, in addition to acidity, redox activity, magnetic properties, and photoelectric properties. Yamase et al. discovered that (NH3Pr...) i )6[Mo7O 26 (Mo7) exhibits excellent antitumor activity against xenografts of CO4-positive human colon cancer and OAT-positive human lung cancer. Larnicol and Bussereau et al. found that at cell-safe doses, (NH4) 17 Na[NaSb9W 21 O 86 HPA-23 (HPA-23) exhibits good antiviral activity against myeloma virus (MLSV), rotavirus (RV), rhabdomyovirus, and herpesvirus (EBV), and is a potential inorganic non-nucleoside analogue (Chem. Rev., 98 (1998) 327-357). However, polysaccharides, due to their large molecular weight, require large dosages and have high tissue toxicity, which are major obstacles to their clinical application. Improving the bioactivity and reducing the tissue toxicity of polysaccharide drugs is a trend in their development. Currently, there are no reports of polysaccharides as inhibitors of Mycobacterium tuberculosis. Summary of the Invention
[0004] The purpose of this invention is to overcome the above-mentioned technical deficiencies and provide a class of heterocyclic ethylenediazine hexamolybdate tetrabutylammonium derivatives, their preparation methods, and applications, thereby solving the technical problem of the need to develop new drugs due to the increased drug resistance of anti-tuberculosis drugs in the prior art.
[0005] To achieve the above-mentioned technical objectives, the technical solution provided by this invention is as follows:
[0006] In a first aspect, the present invention provides a class of heterocyclic ethylenediazene hexamolybdate tetrabutylammonium derivatives, the structural formula of which is shown in Formula I below:

[0013] Compared with the prior art, the beneficial effects of the present invention include:
[0014] (1) The heterocyclic ethylenediazine hexamolybdate tetrabutylammonium derivative of the present invention is an organic derivative obtained by covalently modifying hexamolybdate clusters with heterocyclic acyl hydrazides.

It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.
[0018] In view of the fact that Mycobacterium tuberculosis has developed resistance to current anti-tuberculosis drugs, there is an urgent need to develop a new generation of anti-tuberculosis drugs. This invention provides a class of heterocyclic ethylenediazine hexamolybdate tetrabutylammonium derivatives, their preparation methods and applications. Heterocyclic acyl hydrazides and other organic ligands are used to covalently modify hexamolybdate clusters to develop a new generation of heterocyclic acyl hydrazide-modified polyacid organic derivatives with inhibitory activity against Mycobacterium tuberculosis.
[0019] The organic modification of polyacid clusters in this invention, namely, the substitution of terminal oxygen and / or bridging oxygen by organic ligands, not only regulates the structure of polyacid clusters but also their properties. The covalent bond between the organic ligand and the polyacid cluster not only exhibits the "additive bonding" between the organic ligand and the polyacid cluster, but also, due to the synergistic effect between the polyacid and the organic ligand, produces new properties, giving the resulting heterocyclic ethylenediazine hexamolybdic acid derivative a certain inhibitory activity against Mycobacterium tuberculosis.
[0020] In a first aspect, the present invention provides a class of heterocyclic ethylenediazine hexamolybdate tetrabutylammonium derivatives, the chemical formula of which is: (n-Bu4N)3[Mo6O 18 (=N=NCO-HC]; its structural formula is shown in Equation I below:
[0021]
[0022] HC includes heterocycles such as pyridyl, thiophenyl, furanyl, and pyrazinyl, and n-Bu represents n-butyl.
[0023] Preferably, the heterocyclic ethylenediazine hexamolybdate tetrabutylammonium derivatives include:

[0033] Secondly, the present invention provides a method for preparing a class of heterocyclic ethylenediazine hexamolybdate tetrabutylammonium derivatives, comprising the following steps:
[0034] The organic ligand, dehydrating agent, and tetrabutylammonium octamolate were refluxed in an organic solvent, the organic ligand being a heterocyclic hydrazide;
[0035] After reflux, a heterocyclic ethylenediazine hexamolybdate tetrabutylammonium derivative was obtained.

[0038] Preferably, the organic solvent includes anhydrous acetonitrile.
[0039] Preferably, reflux is performed by heating under stirring for 5–10 hours. It is understood that the heating temperature of the reflux reaction should be controlled near the boiling point of the organic solvent to maintain the reaction system in a boiling state.
[0040] Preferably, the steps for separating and obtaining the heterocyclic ethylenediazine hexamolybdate tetrabutylammonium derivative specifically include: cooling the reflux reaction system to room temperature, filtering to remove impurities, diffusing the obtained filtrate with diethyl ether or methyl tert-butyl ether, and collecting the obtained black or brownish-red crystals to obtain the heterocyclic ethylenediazine hexamolybdate tetrabutylammonium derivative.
[0041] This invention utilizes heterocyclic hydrazides as organic ligands, along with a dehydrating agent and tetrabutylammonium octamolate ((Bu4N)4[Mo8O) 26 The dicyclohexylurea generated is removed by reflux in a dry anhydrous organic solvent at a certain molar ratio. The resulting blackish-red filtrate is diffused through diethyl ether or methyl tert-butyl ether in the gas phase to obtain brownish-red or blackish-red crystals, which are the target products.

[0048] Preferably, the heterocyclic ethylenediazine hexamolybdate tetrabutylammonium derivative has a minimum inhibitory concentration of 1.14–4.55 ug / mL against Mycobacterium tuberculosis in vitro.
[0049] Biological experiments have revealed that the heterocyclic ethylenediazine hexamolybdate tetrabutylammonium derivative of this invention possesses certain inhibitory activity against Mycobacterium tuberculosis and has the potential to become a drug for treating Mycobacterium tuberculosis infection.

[0065] (3) Detection of the inhibitory activity of heterocyclic ethylenediazine hexamolybdate tetrabutylammonium derivative on Mycobacterium tuberculosis H37Rv:
[0066] Take 10 mg of each drug sample and dissolve it in 100 mL of deionized water to prepare an aqueous solution. Then autoclave to obtain the drug solution. Add 0.5 mL of the drug solution to 5.0 mL of 7H10 culture medium. Then dilute the drug solution to the eighth tube using the two-fold dilution method. The ninth tube contains only culture medium (without drug solution) as a control. The tenth tube contains no sample and is an empty tube.
[0067] Using sterile physiological saline containing 0.5% Tween-80, add H37Rv colonies and sterile PBS buffer until the turbidity matches that of a standard McFarland turbidity tube, thus preparing a 1 mg / ml bacterial suspension. Using a heat-sterilized 22 SWG standard inoculation loop, take two loops of the bacterial suspension and add them to a culture tube containing 2 ml of sterile physiological saline to dilute the above bacterial suspension to a final concentration of 10. -3 mg / ml. Using a 22 SWG standard inoculation loop, take one loopful (0.01 ml) of H37Rv bacterial suspension from each of the drug-containing and control culture tubes and streak it evenly onto the surface of the control and drug-containing culture media. Place the inoculated media on a culture rack and incubate at 37°C. Observe the culture progress on days 3 and 7 post-inoculation, and then weekly until the end of the fourth week. After each culture medium check, record the colony growth as required in Table 2.
[0068] Table 2 Colony growth and reporting methods
[0069]
[0070] Visual inspection: Typical colony morphology of Mycobacterium tuberculosis is: opaque pale yellow, rough, dry, raised above the culture medium, sometimes resembling cauliflower. If liquefaction or mold growth is observed in the culture medium, contamination should be reported. Colonies below 4+ have an inhibitory effect on Mycobacterium tuberculosis; the minimum concentration at which this effect is observed is the minimum inhibitory concentration (MIC).
[0071] The inhibitory activity of tetrabutylammonium hexamolybdate (POM-0), heterocyclic ethylenediazine tetrabutylammonium hexamolybdate derivatives POM-1, POM-3, and POM-7 on H37Rv was detected using these drug samples. The results are shown in Table 3.
[0072] Table 3 shows the inhibitory activity of each compound against H37Rv.
[0073]
[0074] The # symbol indicates that the data is from J. Med. Chem. 2004, 47, 3755-3764.
[0075] The anion suppression concentration is the mass concentration of the remaining anion after removing the tetrabutylammonium cation.
[0076] Experimental results showed that POM-1, POM-3, and POM-7 all exhibited varying degrees of inhibitory activity against Mycobacterium tuberculosis H37Rv, with POM-1 showing the best inhibitory effect. The minimum inhibitory concentrations (MICs) of POM-1, POM-3, and POM-7 against Mycobacterium tuberculosis were 1.14 ug / mL, 4.55 ug / mL, and 2.27 ug / mL, respectively. Therefore, the heterocyclic ethylenediazine hexamolybdate tetrabutylammonium derivatives prepared in this invention all showed varying degrees of inhibitory activity against Mycobacterium tuberculosis H37Rv.
