Technical Field
[0001] This invention belongs to the field of biomedical technology and relates to a composition based on plant essential oils or active ingredients and its application in the preparation of drugs for the prevention and treatment of pulmonary edema. Background Technology
[0002] Acute respiratory distress syndrome (ARDS) is one of the major complications of COVID-19 infection, and pulmonary edema is a central link in the pathological process of ARDS. Pulmonary edema is associated with increased alveolar capillary permeability and reduced alveolar fluid clearance. Inflammatory stress, oxidative stress, and immune imbalance are the main factors inducing pulmonary edema. The anti-inflammatory and antioxidant effects of early-stage pulmonary edema treatment with anti-inflammatory drugs (such as the glucocorticoid dexamethasone) and antioxidant drugs (such as the antioxidants N-acetyl-L-cysteine (NAC) and lipoic acid) are undeniable. However, their effectiveness in treating late-stage pulmonary edema, which affects systemic oxygenation and mortality, is very limited. This may be related to the toxicity of glucocorticoids, the choice of treatment regimen, and the limitations and compliance of antioxidants in anti-inflammatory treatment. Therefore, there is an urgent need to develop highly effective and low-toxicity drugs to improve the prevention and treatment of pulmonary edema.
[0003] Previous studies have found that some plant essential oils, extracts or active ingredients have a variety of pharmacological effects such as antibacterial, anti-inflammatory, antioxidant, lipid-regulating, blood pressure-lowering, blood sugar-lowering, liver-protecting, neuroprotective, immunomodulatory, and anti-tumor effects. They have also shown some efficacy in treating acute lung injury (ALI) / acute respiratory distress syndrome (ARDS). However, studies have shown that when a single plant essential oil, extract or active ingredient is used as an active ingredient, its anti-pulmonary edema effect is poor and difficult to achieve the expected results. Summary of the Invention
[0004] To address the shortcomings of existing technologies, the present invention aims to provide a composition based on plant essential oils or active ingredients and its application in the preparation of drugs for the prevention and treatment of pulmonary edema. The multi-component composition provided by the present invention can not only be used for the prevention and treatment of pulmonary edema, but also for the prevention and treatment of respiratory diseases such as COPD, pulmonary fibrosis, and acute respiratory distress syndrome.
[0005] To achieve the above objectives, the technical solution of the present invention is as follows:
[0006] In a first aspect, a composition based on plant essential oils or active ingredients comprises at least three plant essential oils or active ingredients; wherein the plant essential oils or active ingredients have agonistic activity against aquaporins and agonistic activity against sodium-potassium ATPase.
[0007] Intraalveolar fluid clearance is a crucial aspect of pulmonary edema treatment. Alveolar epithelial cells are the primary site for alveolar fluid clearance, and sodium ions (Na+) are the main component. +Active transport is the primary force in clearing fluid from the alveoli. Under normal circumstances, Na+ ions from the alveolar space enter the alveolar epithelial cells via sodium ion channels (ENaC), and are then transported to sodium-potassium ATPase (Na+). + -K + Na+ under the action of ATPase) + Water is pumped into the lung interstitium, creating an osmotic gradient, and then transferred out through aquaporins (AQPs). Therefore, this invention uses aquaporins and sodium-potassium ATPases as important drug targets for screening. Experiments unexpectedly revealed that some plant essential oils, extracts, or active ingredients simultaneously promote the activity of both aquaporins and sodium-potassium ATPases. However, further research showed that these plant essential oils, extracts, or active ingredients, when used as single active ingredients, while promoting the activity of both aquaporins and sodium-potassium ATPases, had limited therapeutic effects on pulmonary edema in animal models. To address this issue, this invention continued experimentation and discovered that when three or more plant essential oils or active ingredients simultaneously promote the activity of both aquaporins and sodium-potassium ATPases are combined, they have a synergistic effect, showing good therapeutic effects on pulmonary edema in animal models. Furthermore, they can be used for the prevention and treatment of respiratory diseases such as COPD, pulmonary fibrosis, and acute respiratory distress syndrome.
[0008] In some implementations, the plants in the essential oils or active ingredients include, but are not limited to, garlic, moringa, peppermint, camphor leaves, camphor tree, cinnamon, cloves, eucalyptus, white pearl tree, thyme, vanilla, and tea tree. Among them, garlic essential oil or its active ingredients are garlic oil and / or diallyl disulfide, etc.; moringa essential oil or its active ingredients are moringa oil and / or moringa isothiocyanates; peppermint essential oil or its active ingredients are peppermint oil and / or menthol, etc.; camphor leaf essential oil or its active ingredients are 1,8-cineole, etc.; borneol essential oil or its active ingredients are borneol oil and / or borneol, etc.; cinnamon essential oil or its active ingredients are cinnamaldehyde and / or eugenol, etc.; clove essential oil or its active ingredients are clove oil and / or eugenol, etc.; eucalyptus essential oil or its active ingredients are eucalyptus oil and / or 1,8-cineole, etc.; white pearl tree essential oil or its active ingredients are methyl salicylate glycoside, etc.; thyme essential oil or its active ingredients are thymol and / or carvacrol, etc.; vanilla essential oil or its active ingredients are vanillin, etc.; tea tree essential oil or its active ingredients are tea tree oil and / or 1,8-cineole, etc.
[0009] Specifically, plant essential oils or plant active ingredients include, but are not limited to, garlic oil, moringa oil, peppermint oil, borneol oil, clove oil, eucalyptus oil, cinnamon essential oil, tea tree essential oil, diallyl disulfide, menthol, moringa isothiocyanate, borneol, cinnamaldehyde, eugenol, 1,8-cineole, methyl salicylate glycoside, thymol, carvacrol, vanillin, etc.
[0010] In some implementations, plant essential oils or active ingredients are ranked by upregulating the expression levels of aquaporin AQP1 and sodium-potassium ATPase-α mRNA genes in A549 cells with pulmonary edema, and the top three from the top five are combined into a composition. The composition of plant essential oils or active ingredients is derived from screening for pulmonary edema aquaporin and sodium-potassium ATPase agonists. The results show that the order in which plant essential oils upregulate the expression levels of aquaporin AQP1 and sodium-potassium ATPase-α mRNA genes in A549 cells with pulmonary edema is garlic oil, moringa oil, peppermint oil, eucalyptus oil, clove oil, borneol oil, and cinnamon oil, while the order in which active ingredients upregulate the expression levels of aquaporin AQP1 and sodium-potassium ATPase-α mRNA genes in A549 cells with pulmonary edema is diallyl disulfide, moringa isothiocyanate-1, menthol, 1,8-cineole, eugenol, borneol, and cinnamaldehyde, etc. Studies have shown that the three-component combination of the top five plant essential oils or active ingredients is more effective than the two-component combination in upregulating the expression of pulmonary edema aquaporin AQP1 and sodium-potassium ATPase-α mRNA genes, indicating the synergistic effect of the components in the plant essential oil or active ingredient combination.
[0011] In some embodiments, at least one plant essential oil or plant active ingredient contains sulfur. Plant essential oils or plant active ingredients containing sulfur may include garlic oil, moringa oil, diallyl disulfide, moringa isothiocyanate-1, etc.
[0012] Based on the above research findings, the following implementation plan is further proposed:

[0018] In some embodiments, the mixture consists of Moringa isothiocyanate-1, L-menthol, and 1,8-cineole in a mass ratio of 4-8:1-2:4-12, preferably 4:1:4.
[0019] To further improve the volatility (odor), irritation, and stability of compositions of plant essential oils or active ingredients, the following implementation scheme is proposed:
[0020] In some embodiments, the dosage form of the composition is one of the following: injectable liquid formulation, oral liquid formulation, microemulsion, nanoemulsion, liposome, nanopolymer formulation, soft capsule formulation, aerosol, nebulizer, powder aerosol, nasal spray, inclusion complex formulation, etc., preferably a soft capsule formulation, nanoemulsion or inclusion complex formulation.
[0021] In some embodiments, the composition further includes pharmaceutical excipients. Specifically, the excipients include one or more of fillers, emulsifiers, co-emulsifiers, capsule shell materials, preservatives, inclusion agents, etc.
[0022] The soft capsule formulation is a microemulsion soft capsule. Specifically, the excipients in the capsule core include an oil phase filler, an emulsifier, and a co-emulsifier. More specifically, plant organosulfur compounds and a flavor-masking and cooling system are used as active ingredients, and the mass ratio of the active ingredient, oil phase filler, emulsifier, and co-emulsifier is 1-10:1-10:1-10:1-5.

[0052] To enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention will be described in detail below with reference to specific embodiments.
[0053] Example 1: Activity determination of single plant essential oils and their active ingredient, aquaporin agonists.
[0054] Based on literature review and preliminary experiments, the selected single plant essential oils include garlic oil, moringa oil, peppermint oil, eucalyptus oil, clove oil, borneol oil, and cinnamon oil; the selected single plant active ingredients include diallyl disulfide, moringa isothiocyanate-1, menthol, 1,8-cineole, eugenol, borneol, and cinnamaldehyde.
[0055] Aquaporin agonist activity test: (1) Pulmonary edema modeling: 20 μg / mL lipopolysaccharide (LPS) solution was used to stimulate each well 4×10 5 (2) Drug administration and sample preparation: Plant essential oil or its active ingredients were added to a 96-well plate containing LPS-stimulated lung edema A549 cell culture medium at a concentration of 30 µg / mL and cultured for 24 hours. The relevant test samples were prepared according to the experimental steps of RNA extraction, RNA reverse transcription and RT-PCR reaction in the conventional RT-PCR detection technology. (3) Determination of the expression level of aquaporin APQ1 mRNA gene: The expression level of aquaporin AQP1 mRNA gene in lung edema A549 cells was detected by RT-PCR technology according to the experimental steps of RT-PCR detection.
[0056] The order in which plant essential oils upregulated the expression level of aquaporin AQP1 mRNA in A549 cells with pulmonary edema was garlic oil, moringa oil, peppermint oil, eucalyptus oil, clove oil, borneol oil, and cinnamon oil, while the order in which the active ingredients of plant essential oils upregulated the expression level of aquaporin AQP1 mRNA in A549 cells with pulmonary edema was diallyl disulfide, moringa isothiocyanate-1, menthol, 1,8-cineole, eugenol, borneol, and cinnamaldehyde, among others.
[0057] Example 2: Determination of the activity of a single plant essential oil and its active ingredient, sodium-potassium ATPase agonist.
[0058] The preferred single plant essential oil and its active ingredients in this embodiment are described in Example 1.
[0059] Activity test of sodium-potassium ATPase agonist: The relevant experimental operations were completed according to the experimental steps of pulmonary edema modeling, drug administration and sample preparation in Example 1; Determination of sodium-potassium ATPase-α mRNA level: The gene expression level of sodium-potassium ATPase-α mRNA in pulmonary edema A549 cells was detected by RT-PCR technology according to the experimental steps of RT-PCR detection.
[0060] The order in which plant essential oils upregulated the expression level of sodium-potassium ATPase-α mRNA gene in A549 cells with pulmonary edema was garlic oil, moringa oil, peppermint oil, eucalyptus oil, clove oil, borneol oil, and cinnamon oil, while the order in which the active ingredients of plant essential oils upregulated the expression level of sodium-potassium ATPase-α mRNA gene in A549 cells with pulmonary edema was diallyl disulfide, moringa isothiocyanate-1, menthol, 1,8-cineole, eugenol, borneol, and cinnamaldehyde, among others.
[0061] Example 3: Determination of the synergistic effect of plant essential oils and their multi-component active ingredients as aquaporin agonists.
[0062] Based on the activity assay results of single plant essential oils and their active ingredient, aquaporin agonists, in Example 1, garlic oil, moringa oil, peppermint oil, eucalyptus oil, and clove oil were identified as the top five optimal aquaporin APQ1 agonists. Using essential oils containing organosulfur compounds as the primary components, the following three-component (1:1:1 ratio) and two-component essential oil compositions (1:1 ratio) were optimized: garlic oil + peppermint oil + eucalyptus oil, garlic oil + peppermint oil + clove oil, moringa oil + peppermint oil + eucalyptus oil, moringa oil + peppermint oil + clove oil, garlic oil + peppermint oil, garlic oil + eucalyptus oil, garlic oil + clove oil, moringa oil + peppermint oil, moringa oil + eucalyptus oil, and moringa oil + clove oil. Following the aquaporin agonist activity assay procedures in Example 1, RT-PCR was used to detect the effects of the above three-component and two-component essential oil compositions on aquaporin AQP1 in A549 cells with pulmonary edema. The effect of mRNA gene expression level was measured, and the results showed that the activity of the above three-component composition was better than that of the corresponding two-component composition, indicating that the preferred multi-component essential oil composition has a synergistic effect in upregulating aquaporin AQP1.
[0063] Based on the activity determination results of single plant essential oils and their active ingredient aquaporin agonists in Example 1, the top 5 active ingredients of the plant essential oils include diallyl disulfide, moringa isothiocyanate-1, L-menthol, 1,8-cineole, and eugenol; using the active ingredients containing organosulfur compounds as the primary components, the following three-component (ratio 1:1:1) and two-component active ingredient compositions (ratio 1:1) were optimized: diallyl disulfide + L-menthol + 1,8-cineole, diallyl disulfide + L-menthol + eugenol, moringa isothiocyanate-1 + The following compounds were selected: L-menthol + 1,8-cineole, Moringa isothiocyanate-1 + L-menthol + eugenol, diallyl disulfide + L-menthol, diallyl disulfide + 1,8-cineole, diallyl disulfide + eugenol, Moringa isothiocyanate-1 + L-menthol, Moringa isothiocyanate-1 + 1,8-cineole, Moringa isothiocyanate-1 + eugenol. Following the aquaporin agonist activity assay procedure in Example 1, RT-PCR was used to detect the effects of the above three-component and two-component active ingredient compositions on the expression level of aquaporin AQP1 mRNA in pulmonary edema A549 cells. The results showed that the activity of the three-component compositions was superior to that of the corresponding two-component compositions, indicating that the preferred multi-component active ingredient compositions have an additive effect in upregulating aquaporin AQP1.
[0064] Example 4: Determination of the synergistic effect of plant essential oils and their multi-component active ingredients as aquaporin agonists.
[0065] Based on the experimental procedures for determining the activity of a single plant essential oil and its active ingredient, sodium-potassium ATPase agonist, in Example 2, the additive effect of the plant essential oil or its multi-component composition of active ingredients in Example 3 on the activity of sodium-potassium ATPase-α agonist was evaluated. The test results showed that the activity of the above three-component plant essential oil or its active ingredient composition was better than that of the corresponding two-component plant essential oil or its active ingredient composition, indicating that the preferred multi-component essential oil composition has additive effect in upregulating sodium-potassium ATPase-α.
[0066] Example 5: Screening of active ingredients and excipients for soft capsules CPD0351 based on garlic oil composition.
[0067] Based on the screening results of aquaporins and sodium-potassium ATPase agonists in Examples 1-4 above, and the pharmacological effects of related components, and taking into account the target indications for the prevention and treatment of pulmonary edema of the developed soft capsules, such as oxidative stress and inflammatory stress, the effective components of the soft capsule CPD0351 based on garlic oil composition were determined to be garlic oil, peppermint oil, and eucalyptus oil. According to the Chinese Pharmacopoeia, the recommended dosage of relevant traditional Chinese medicines (or extracts, etc.) in domestic and foreign studies, the content of effective components, and their preliminary experiments, the mass ratio of medicinal plant essential oils in the formulation of soft capsule CPD0351 was determined to be approximately 4-8:1-2:4-12.
[0068] Microemulsion soft capsules have stringent formulation requirements. The oil phase, emulsifiers, and co-emulsifiers must be non-toxic, non-irritating, and biocompatible. The type and ratio of these components can affect the final product's performance, such as droplet size, zeta potential, and polydispersity index. Therefore, the optimal composition and ratio are crucial for soft capsule formulation. The oil phase used in microemulsion soft capsules should allow for appropriate penetration and interaction with emulsifier molecules on the emulsion interface film, and readily form an interfacial film with the emulsifier. Thus, the molecular size of the oil phase is significant for the formation of the soft capsule microemulsion. Suitable oil phases for selection include soybean oil, corn oil, olive oil, rapeseed oil, peanut oil, isopropyl myristate, castor oil, isopropyl laurate, ethyl oleate, and medium-chain triglycerides. Emulsifiers can be classified according to the type of ion, including anionic, cationic, amphoteric, and nonionic types. Considering safety and irritation in application, nonionic emulsifiers are more widely used because they have the lowest toxicity and are less affected by changes in pH and ionic strength. The hemolytic effect of emulsifiers must also be considered. Nonionic emulsifiers available for screening include fatty acid sorbitan, polysorbates, polyoxyethylene fatty acid esters (trade name Myrj), polyoxyethylene fatty alcohol ethers (trade name Brij), polyoxyethylene polyoxypropylene copolymers (polyether type), sucrose fatty acid esters, and glyceryl monostearate. Preferred emulsifiers include polysorbates (such as Tween-20, Tween-40, Tween-60, and Tween-80), fatty acid sorbates (such as Span-20, Span-40, Span-60, and Span-80), and castor oil polyoxyethylene ethers (such as Kolliphor EL, Marlowet 40, and Emulgin RO). 40) Polyoxyethylene hydrogenated castor oil (such as Kolliphor RH-40, Kolliphor RH-60), etc. Co-emulsifiers can improve the strength and flexibility of the film, reduce emulsifier consumption, and facilitate microemulsion formation. Co-emulsifiers should be pharmaceutical-grade short-chain alcohols or nonionic surfactants with suitable hydrophilic-lipophilic balance (HLB). Suitable co-emulsifiers include ethanol, ethylene glycol, propylene glycol, glycerol, n-butanol, diethylene glycol monoethyl ether, glycerol, polyethylene glycol (such as PEG 400, PEG 600), polyglycerol esters, etc.
[0069] The screening of the oil phase used in the soft capsule CPD0351 based on garlic oil composition was divided into two parts: (1) The miscibility of the mixture of CPD0351 essential oil composition and different oil phases was observed after 48 hours. Soybean oil, corn oil, olive oil, rapeseed oil, peanut oil, castor oil, isopropyl myristate, isopropyl laurate, ethyl oleate, medium chain triglycerides and other oil phases did not show layering or discoloration; (2) The mixture of CPD0351 essential oil composition, different oil phases, emulsifier Tween-80 or Span-80 was observed after 48 hours. The Span-80 group did not show discoloration or layering, while the mixture of (1) medium oil phase and Tween-80 showed different degrees of discoloration or layering except for ethyl oleate and medium chain triglycerides.
[0070] The garlic oil-based soft capsule CPD0351 was mixed with the oil phase, emulsifier, and co-emulsifier in a pre-set 1:1:1 ratio and shaken to form a clear, transparent solution. 0.1 g of the above mixture was taken and added to 50 mL of preheated 37°C pure water. The mixture was shaken, and the combinations that formed a transparent solution were recorded. The types of oil phase, emulsifier, and co-emulsifier were determined using a pseudo-three-phase diagram. The preferred emulsifiers were Tween-80, Span-80, Kolliphor RH-40, and mixtures thereof, while ethanol, diethylene glycol monoethyl ether, polyethylene glycol-400, and mixtures thereof were preferred co-emulsifiers.
[0071] The ideal formulation of essential oils, filler oil phase, emulsifier and co-emulsifier was studied using pseudo-three-phase diagrams. The optimal ratio was determined to be 1-10:1-10:1-10:1-5. The preferred filler oil phase, emulsifier and co-emulsifier were medium-chain triglycerides, Tween-80 and polyethylene glycol-400, respectively.
[0072] Example 6: Screening and preparation of capsule material for garlic oil-based soft capsules CPD0351 series.
[0073] Based on the screening in Example 5, the mass ratio of the active ingredients—garlic oil, peppermint oil, and eucalyptus oil—in the garlic oil-based soft capsule composition CPD0351 was determined to be 4:1:4. The initial ratio of the drug essential oil, medium-chain triglycerides in the oil phase, and emulsifier Tween-80 in the contents was set at 9:4:12. Commonly used soft capsule materials include gelatin, plasticizer (glycerin), and water. The capsule shell was prepared according to the conventional ratio of 3:1:3. By conducting compatibility studies between the capsule shell and the contents, gelatin from different sources and with different gel strengths was screened. The specific ingredients for CPD0351A are shown in Table 1. The capsule shell was cut into 0.5 × 1 cm pieces and placed in a sample vial. 1 mL of CPD0351 contents was added. According to the influencing factor test conditions, the capsules were placed under high temperature, high humidity, and light conditions. A separate gelatin block was placed as a blank control under each condition. Samples were taken on days 5 and 10 to observe and photograph changes. Three samples were taken in parallel for each group. The selected gelatin sources and gel strengths included Fengyuan 150 gel strength, Fengyuan 180 gel strength, Pingda 150 gel strength, and Pingda 180 gel strength. Observation of the appearance changes of the capsule shell showed that none of the capsule shells melted or deformed under various conditions. The color of the capsule shells deepened under high temperature conditions, while the color change was minimal under high humidity and light conditions. Fengyuan 180 gel strength showed almost no change.

[0075]
[0076] The preparation of soft capsules includes the following steps:

[0121] A rat model of COPD was established by intraperitoneal injection of cigarette smoke extract solution (CSE). Male Sprague-Dawley rats (weighing 130-150 g) were selected as the research subjects, and budesonide was used as the positive control drug. Male Sprague-Dawley rats (28 in total) were randomly divided into 4 groups of 7 rats each: (1) Control group: While rats in other groups received CSE injection to establish the model, rats in the control group received the same volume of phosphate injection (PBS); (2) COPD model group: 1 mL of CSE solution was injected intraperitoneally on days 1, 8, 15 and 22 of the experiment; (3) CPD0351A treatment group: 150 mg / kg (calculated based on garlic oil content) of CPD0351A soft capsules, which were dispersed in an aqueous solution to prepare a suspension, and were administered orally once a day starting from day 2; (4) Budesonide positive control group: 10 mg / kg of budesonide suspension, administered at the same time as CPD0351A. All animals were euthanized painlessly, and bronchoalveolar lavage fluid (BALF) and lung tissue were collected as samples for subsequent experimental studies.

The efficacy of CPD0351A in treating alveolar damage, anti-inflammatory stress, anti-oxidative stress, immunomodulation, and reversing budesonide resistance are as follows: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, these results indicate that CPD0351A is significantly more effective than budesonide in terms of antioxidant and immunomodulatory effects; furthermore, CPD0351A reverses budesonide resistance by regulating the PI3K signaling pathway (it is ineffective against p-Akt overexpression in COPD). Figure 5 This indicates that CPD0351A can be used in combination with hormone drugs such as budesonide to achieve a special effect of synergistic effect and reduced toxicity.

First, administer the drug by gavage according to the above protocol, once a day for 7 consecutive days. On the eighth day, use a micro-needle to drip LPS or saline into the trachea of the rats. After each group of rats is exposed to saline or LPS for 24 hours, they are euthanized. 24 hours after drug withdrawal, all animals are sacrificed painlessly.
