Abstract
Description
[0001] The present invention belongs to the fields of organic compound synthesis, pharmaceutical technology, food engineering, etc., and specifically relates to a class of pyridone endoperoxides with antibacterial and antiviral activities and their applications. Background Art
[0002] Microorganisms include bacteria, fungi, and viruses, etc., which play important roles in the environment and human health. However, under certain conditions, the above microorganisms can cause diseases and food contamination, etc. For example, Cutibacterium acnes (C. acnes), a Gram-positive anaerobic bacterium, belongs to the normal skin flora and mainly parasitizes in areas such as sebaceous glands and hair follicles, such as on the face, scalp, chest, and back. The lipase produced by C. acnes can decompose the fat in the sebaceous glands, leading to the blockage of hair follicles and sebaceous glands and triggering acne. In addition, C. acnes is not only associated with suppurative arthritis, discitis, and osteomyelitis, but also often causes infections in the shoulder, hip, or knee during surgery. Escherichia coli can cause skin and soft tissue infections under specific circumstances, such as cellulitis, skin abscess, surgical site infection, pressure ulcer infection, skin diseases accompanied by urinary tract infection, etc. The growth and reproduction of Escherichia coli can lead to food spoilage, producing peculiar smells, abnormal colors, and harmful substances, reducing the quality and safety of food. Foods contaminated with Escherichia coli may cause food poisoning, manifested as diarrhea, vomiting, abdominal pain, and fever, etc. Candida albicans is a common fungus, which can cause cutaneous candidiasis, especially in moist and friction areas, such as the armpit, groin, nail bed, etc., often manifested as redness, eczema-like changes, accompanied by itching and pain. Candida albicans can also cause oral infections, commonly seen on the surface of oral mucosa, especially when the immune system is damaged, manifested as white or cheesy plaques, accompanied by oral pain and a burning sensation. In addition, enveloped viruses such as herpes virus, human papillomavirus, molluscum contagiosum virus, rubella virus, and measles virus endanger human health. Developing effective drugs that can effectively kill bacteria, fungi, and viruses and treat skin diseases caused by these microorganisms is very crucial. At the same time, it is also of great significance to develop disinfectants and food preservatives that can efficiently sterilize. Currently, antibiotics and skin disinfectant drugs cannot effectively inhibit the growth of the above microorganisms, and the research and development of diverse disinfectants and preservatives are an urgent task.
[0003] The cell membrane plays a key role in maintaining the physiological functions of microorganisms, and damaging the cell membrane structure of microorganisms is one of the important directions in the research and development of antibacterial, antifungal, and antiviral drugs. Singlet oxygen ( 1 O 2) Singlet oxygen, namely excited state oxygen molecules, is a class of highly reactive substances that can damage biological molecules such as cell membranes, organelles, and proteins. My previous work has demonstrated that endoperoxides, as singlet oxygen carriers, can simultaneously release singlet oxygen and carrier molecules, which can damage cancer cells, cell membranes, and organelles, leading to apoptosis of cancer cells and showing great potential for anti-cancer. However, the antibacterial, antiviral capabilities of endoperoxides, singlet oxygen, and carrier molecules, as well as their related applications in treating skin diseases and food preservation, have not been studied yet. Summary of the Invention
[0004] The present invention has developed a class of pyridone endoperoxides and demonstrated that a series of endoperoxides can be converted into pyridone derivatives while releasing singlet oxygen and triplet oxygen. The series of endoperoxides can effectively kill bacteria such as Propionibacterium acnes, Escherichia coli, and Staphylococcus aureus, fungi such as Candida albicans, and microorganisms such as human papillomavirus and herpes simplex virus, and have the ability to treat multiple skin diseases. It is expected to be developed into a first-line drug for treating skin diseases caused by pathogen invasion, mainly involving bacterial skin diseases, fungal skin diseases, and viral skin diseases caused by pathogen infections. At the same time, it can be used for the treatment of diseases such as infections after shoulder and other joint surgeries and pressure ulcers. In addition, the series of endoperoxides can also be used in the fields of food preservation and disinfectant preparation.

[0191] Example 2: Test on the drug delivery ability of endoperoxides
[0192] Singlet oxygen trapping experiment: Using DPBF as a singlet oxygen trapping reagent, the release of singlet oxygen by the compound was monitored. The experimental procedure was as follows: Representative compounds such as E1 or E11 (750 μM) and DPBF (singlet oxygen scavenger, 37.5 μM) were dissolved in DMF. At 37 °C under dark conditions, the absorption at 417 nm was monitored using a UV-visible spectrophotometer at different time intervals to analyze the release of singlet oxygen. The results showed that endoperoxides could efficiently release singlet oxygen (as Figures 3 - 4 shown).
[0193] Drug release half-life: Endoperoxides release raw materials, singlet oxygen, and triplet oxygen through a retro-cycloaddition reaction. The whole process follows the first-order kinetic rate equation, and the half-life can be calculated by the formula t 1 / 2 = 0.693 / k. The representative experimental procedure was as follows: Weigh approximately 2 mg of endoperoxide E5 and dissolve it in deuterium water, then place it in a water bath at 37 °C. The 1H NMR spectra of the solution were measured at 6 hours, 10 hours, 23 hours, and 35 hours respectively. The half-life of the retro-cycloaddition reaction was calculated through the characteristic peaks of E5 and P5 between 6.25 - 6.75 ppm: t 1 / 2 = 11.9 hours (at 37 °C, in deuterium water, as Figure 5 shown).
[0194] Drug release yield: Using tetramethylethylene as a singlet oxygen trapping reagent, the drug release yield of endoperoxides was calculated using 1H NMR spectra according to the above method. Taking endoperoxide E5 as an example, the results showed that after 1 mole of E5 underwent a complete reverse reaction, 1 mole of P5, 0.5 mole of singlet oxygen, and 0.5 mole of triplet oxygen were released (as Figure 6 shown).

[0215] Adding in packaging: Some foods add the internal peroxide preservative during packaging to extend the shelf life. This method is usually used for packaged and sealed foods such as meat products and dairy products.
[0216] Combined use: In order to enhance the anti-corrosion effect, multiple preservatives are often used in combination. For example, the internal peroxide is combined with one or more of other anti-corrosion components such as benzoic acid, sorbic acid, nitrates, nitrites, etc.
[0217] Dosage control: The addition amount of the internal peroxide preservative must be strictly controlled within the range permitted by regulations to ensure food safety. Uniform distribution: The preservative must be uniformly distributed in the food to ensure the anti-corrosion effect of the whole food. Scope of application: The internal peroxide preservative is not only applicable to foods required by humans and animals, but also applicable to medicines and other items that need to ensure quality through antibacterial.

An antibacterial drug solution was prepared and subjected to a two-fold dilution series (initial concentration of 256 μg / mL, diluted successively to 128 μg / mL, 64 μg / mL, 32 μg / mL). 50 μL of the antibacterial endoperoxide solution at different concentrations (0, 32 μM, 64 μM, 128 μM) was added to each well. Let it stand for a moment to allow the drug solution to diffuse into the agar. The plate was incubated at 37 °C for 48 hours. The antibacterial effect of the drug was observed based on the growth of Candida albicans. A negative control group (without endoperoxide) was set, and the above experiment was repeated three times.

[0226] For other antiviral experiments, refer to the above procedure.
[0227] Example 9: Psoriasis treatment experiment
[0228] Topical application of imiquimod cream was used to induce psoriasiform skin lesions in mice to establish a psoriasis model. After psoriasis induction, the mice were randomly divided into five groups and treated with endoperoxide ointment topically every day. At the same time point every day, an appropriate amount of the drug was evenly applied to the skin lesion area. The treatment continued for 21 days. The initial body weight and skin condition of each mouse were recorded. The changes in the skin lesions, including erythema, scale, and induration, were observed and recorded daily. The body weight of the mice was measured and recorded daily to monitor the effect of the drug on the overall health status.
[0229] Example 10: Acne regression test
[0230] Six patients with moderate acne were randomly divided into two groups, with 3 patients in the treatment group and 3 patients in the control group. After cleansing their faces in the morning and evening, each patient in the treatment group applied the gel prepared in Example 2 (Compound E11, content 5%) to the acne areas, while the control group did not receive any treatment. During the treatment process, the time for acne regression was photographed and recorded, and the curative effect was evaluated through the lesion regression rate. The recorded results are shown in Table 5.
[0231] Curative effect evaluation criteria: Cure: The lesion regression rate after treatment > 90%; Marked effect: The lesion regression rate is 60% - 90%; Effective: The lesion regression rate is 20% - 59%; Ineffective: It fails to meet the effective standard after treatment. The lesion regression rate = (the number of lesions before treatment - the number of lesions after treatment) / the number of lesions before treatment × 100%.
[0232] Safety indicators: Observe the occurrence of pigmentation and erythema in both groups, and evaluate the occurrence of pain in patients. Safe: No obvious pigmentation, erythema, and pain; Safety hazard: Appear mild pigmentation, erythema, and mild pain; Unsafe: Appear obvious pigmentation, erythema, and significant pain.
[0233] Example 11: Evaluation of the anti - microbial ability of internal - peroxide food preservatives
[0234] Thoroughly wash fresh strawberries with clean water to remove surface dirt and impurities. Rinse again with sterile distilled water to remove possible chemical residues. Gently dry the strawberries with sterile gauze or paper towels, avoiding damage to the epidermis. Use ethanol solutions of representative internal - peroxide E5 and aqueous solutions of E11 (concentrations 0.05%, 0.1%, 0.5%, 1%, 2%). Soak the pretreated strawberries in different concentrations of anti - microbial internal - peroxide solutions (ten in each group) for 5 minutes to ensure complete wetting of the strawberry surface. The control group was soaked in sterile distilled water. Dry the soaked strawberries in a sterile environment, avoiding direct sunlight. Place the treated strawberries at room temperature and observe the appearance changes of the strawberries every 3 days, including mildew, color change, and texture change. Record the decay situation and mold growth of the strawberries.

[0264] As can be seen from Table 7, the representative endoperoxide E11 gel can effectively kill Propionibacterium acnes and has the effects of keratolysis and exfoliation, and is expected to be developed into an effective drug for the treatment of acne. No obvious pigmentation, erythema or pain occurred during the treatment process, which proved that the series of compounds had excellent safety. Thus, it can be seen that the series of endoperoxides can be developed into effective drugs for the treatment of acne, with high efficacy and good safety. In addition, dosage forms such as gels and creams of the above-mentioned endoperoxides still showed excellent therapeutic effects and safety.
