Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of Chinese medicine preparations, and in particular to a group of innovative Chinese medicine preparations for enhancing anti-cancer therapeutic effects and a preparation process thereof. Background Art
[0002] Cancer is a disease that seriously threatens human health, and its morbidity and mortality rates are rising worldwide. Existing cancer treatments mainly include surgery, radiotherapy, chemotherapy, immunotherapy, etc., but these methods are often accompanied by significant side effects and high treatment costs. In recent years, Chinese medicine preparations have gradually become an important means of adjuvant cancer treatment due to their multi-target effects and relatively low toxic side effects. However, existing Chinese medicine anticancer preparations still have the following shortcomings:
[0003] Single-ingredient anticancer agents have limited efficacy:
[0004] Traditional Chinese medicine anticancer preparations mostly use a single or a few Chinese medicine ingredients. Although these preparations show certain efficacy on certain specific anticancer targets, they are difficult to cope with the complex pathological characteristics of tumors due to the lack of multi-target and multi-pathway combined effects. The occurrence and development of tumors involve multiple mechanisms such as multiple gene mutations, abnormal cell signaling pathways, and immune escape. Relying solely on the action of a single ingredient is often not enough to fully inhibit the growth and spread of cancer cells. In addition, single-ingredient Chinese medicine preparations are metabolized quickly in the patient's body and have a short duration of action, resulting in insufficiently lasting efficacy. Therefore, the single-ingredient preparations in the prior art have limited efficacy and are difficult to meet clinical needs.
[0005] The extraction process is backward and the active ingredients are not fully utilized:
[0006] Existing Chinese medicine preparation production processes usually adopt traditional water extraction or alcohol extraction methods, which often require high temperature or long-term heating during the extraction process, which not only easily leads to the degradation or loss of some heat-sensitive active ingredients, but also may cause a high impurity content in the extract, affecting the quality and efficacy of the preparation. At the same time, the traditional extraction method is not sufficient to destroy the plant cell wall, resulting in many macromolecular active ingredients (such as polysaccharides, saponins) being difficult to release completely, causing waste of effective ingredients, low extraction efficiency, and poor product stability. Therefore, the extraction process in the prior art is in urgent need of improvement to improve the extraction efficiency and product purity of active ingredients.
[0007] Poor drug targeting and poor treatment effect:
[0008] Most of the existing Chinese medicine anticancer preparations are non-targeted preparations, lacking effective targeted delivery technology, resulting in uneven distribution of drugs in the body, a large amount of drugs accumulating in normal tissues, producing unnecessary toxic side effects, and insufficient drug concentration at the tumor site, unable to fully exert its therapeutic effect. Especially in the blood circulation system, drugs are easily cleared or metabolized quickly, further reducing their bioavailability and efficacy. Therefore, the Chinese medicine preparations in the prior art face the problems of poor targeting and low effectiveness, making it difficult to achieve ideal results in clinical treatment.
[0009] Poor formulation stability and bioavailability:
[0010] Traditional Chinese medicine ingredients are complex and easily degraded, and the stability of the preparations in the prior art is often not ideal. In the gastrointestinal environment, many active ingredients of traditional Chinese medicine are easily destroyed due to the acidic environment or digestive enzymes, resulting in low bioavailability of the drug. At the same time, the solubility of most traditional Chinese medicine ingredients is poor, which further limits their absorption effect. Therefore, the bioavailability of existing traditional Chinese medicine preparations in the body is generally low, affecting the therapeutic effect and patient compliance.
[0011] Therefore, the present invention proposes a group of innovative Chinese medicine preparations and preparation processes thereof for enhancing anti-cancer therapeutic effects to address the deficiencies of the prior art. Summary of the invention
[0012] In view of the shortcomings of the prior art, the present invention provides a group of innovative Chinese medicine preparations and their preparation processes for enhancing the anti-cancer therapeutic effect, which solve the problems of limited efficacy, insufficient utilization of active ingredients, poor drug targeting, low stability and bioavailability of existing Chinese medicine anti-cancer preparations.
[0013] To achieve the above objectives, the present invention is implemented by the following technical scheme: a group of innovative Chinese medicine preparations for enhancing anti-cancer therapeutic effects, comprising the following components by weight:
[0014] Astragalus: Contains polysaccharides and saponins, which can enhance immune function and improve the body's resistance to tumors.
[0015] Scutellaria barbata: Rich in flavonoids, it has the effect of inhibiting cancer cell proliferation and promoting apoptosis.
[0016] Oldenlandia diffusa: It mainly contains polysaccharides, which have the effects of clearing heat and detoxifying, anti-cancer and immune regulation.
[0017] Yew: Contains paclitaxel, which directly inhibits the mitosis of cancer cells and prevents tumor growth.
[0018] Ganoderma lucidum: Contains polysaccharides and triterpenes, which can effectively enhance immunity and inhibit the spread of tumors.
[0019] Ginseng: Rich in ginsenosides, it can enhance physical strength, improve immunity and anti-oxidation effects.
[0020] Panax notoginseng: The main ingredient is Panax notoginseng total saponins, which has hemostatic, blood-activating and blood-stasis-removing and anti-tumor effects.
[0021] Gynostemma pentaphyllum: Rich in saponin compounds, it has anti-tumor, antioxidant and immune-enhancing effects.
[0022] Atractylodes: Mainly contains volatile oils and polysaccharides, which have anti-cancer and immunity-enhancing effects.
[0023] Curcuma: Contains volatile oil, which has the effects of promoting blood circulation, removing blood stasis and anti-tumor.
[0024] Salvia miltiorrhiza: Rich in tanshinone and flavonoids, it can improve microcirculation and inhibit the proliferation of cancer cells.
[0025] Houttuynia cordata: Contains volatile oils and flavonoids, which have anti-inflammatory and anti-tumor effects.
[0026] Jiazhu: It has the effects of removing blood stasis, dispersing nodules, reducing swelling and relieving pain. It can enhance immune function and inhibit tumor growth.
[0027] Cordyceps: Contains polysaccharides and adenosine ingredients, which have the effects of enhancing immunity, anti-tumor and anti-fatigue.
[0028] Centipedes and whole insects: They have the effects of dispelling wind and dredging meridians, reducing swelling and relieving pain, anti-tumor and enhancing immunity, especially have a significant inhibitory effect on stubborn tumors.
[0029] Sophora japonica: Rich in polysaccharides, it has significant anti-tumor effects, especially in inhibiting solid tumors such as liver cancer and gastric cancer.
[0030] This multi-component Chinese medicine formula enhances the overall anti-cancer effect of the preparation through the synergistic effect of multiple ingredients. Each ingredient plays a role in different anti-cancer mechanisms (such as inhibiting cancer cell proliferation, inducing cell apoptosis, improving immunity, etc.). Compared with single-ingredient Chinese medicine preparations, it can more comprehensively respond to the complex pathological characteristics of cancer, provide multi-target anti-cancer treatment, significantly improve treatment effects and reduce side effects.
[0031] Preferably, the preparation is in the form of granules, tablets, capsules, pills or injections.
[0032] The choice of multiple dosage forms enables the preparations to be flexibly applied to different clinical situations and to suit the needs of different patients. Granules, tablets, pills and capsules provide convenient oral options to improve patient compliance; injections provide a fast and effective anti-cancer treatment approach.
[0033] Preferably, the extracts of Gynostemma pentaphyllum, ginseng, Atractylodes macrocephala and Ganoderma lucidum in the preparation are pretreated by an enzymatic hydrolysis method, which includes using cellulase and pectinase to treat at a pH of 4.5-6.5 and a temperature range of 35-45°C for 1-2 hours to enhance the release efficiency of polysaccharide and saponin components, and then prepared into powder by spray drying.
[0034] The enzymatic pretreatment significantly improves the release efficiency and extraction rate of polysaccharide and saponin active ingredients, retains the active ingredients of Chinese medicinal materials to the maximum extent, and enhances the anti-cancer effect of the preparation. Compared with the traditional high-temperature water extraction method, the enzymatic method of the present invention is carried out at a lower temperature and a suitable pH value, effectively avoiding the degradation and loss of active ingredients and improving the quality and stability of the preparation.
[0035] Preferably, the active ingredients of the preparation include astragalus polysaccharide, Scutellaria barbata flavonoids, Hedyotis diffusa polysaccharide, Taxus paclitaxel, ginsenosides, notoginseng total saponins, cordyceps polysaccharide and Sophora polysaccharide, and the active ingredients are processed by multi-layer coated microsphere technology, the inner layer of the microsphere is formed by gelatin and chitosan, and the outer layer is composed of sodium alginate and gelatin complex, wherein the ratio of the inner layer material is 1:1 to 1:2, and the ratio of the outer layer material is 2:1 to 3:1, and the diameter range of the microsphere is 500 nanometers to 5 micrometers.
[0036] The multi-layer coated microsphere technology enhances the stability, targeting and sustained release of the preparation. Compared with non-coated traditional Chinese medicine preparations, the present invention can significantly increase the concentration of the drug in the tumor site, prolong the drug action time, and reduce the toxic side effects on normal tissues.
[0037] Preferably, a preparation process of a group of innovative Chinese medicine preparations for enhancing anti-cancer therapeutic effects comprises the following steps:
[0038] S1. Cleaning, slicing and drying of medicinal materials;
[0039] S2, using ultrasonic-assisted water extraction and supercritical CO2 extraction technology to extract the active ingredients of traditional Chinese medicine;
[0040] S3, nano-encapsulation and microencapsulation of active ingredients through targeted nano-delivery technology and multi-layer coated microsphere technology;
[0041] S4. The extract is dried by freeze drying combined with spray drying technology and prepared into granules, tablets, capsules, pills or injections.
[0042] The combined use of ultrasonic-assisted water extraction and supercritical CO2 extraction technology improves the extraction efficiency and purity of water-soluble and fat-soluble active ingredients. Ultrasonic-assisted extraction technology can effectively destroy cell walls, improve extraction efficiency, and avoid component degradation caused by high temperature; supercritical CO2 extraction technology can selectively extract fat-soluble active ingredients and reduce organic solvent residues.
[0043] Targeted nano-delivery technology combined with microencapsulation improves the targeting and bioavailability of drugs, reduces toxicity to normal tissues, and enhances anti-cancer effects. The combined use of freeze drying and spray drying ensures drug stability and retention of active ingredients.
[0044] Preferably, the operating conditions of the ultrasonic-assisted water extraction method in step S2 include an extraction temperature of 45-55°C, an extraction time of 40-50 minutes, an ultrasonic frequency of 20-40kHz, an ultrasonic power of 300-500 watts, a ratio of solvent to medicinal material of 10:1 to 15:1, and the obtained extract is concentrated under reduced pressure at 60-80°C to 1 / 3 to 1 / 5 of the original volume.
[0045] The reasonable setting of ultrasonic frequency, power and extraction time ensures the efficiency and stability of the extraction process, effectively destroys the cell structure of medicinal materials and promotes the release of effective ingredients. At the same time, the extraction is carried out at a relatively low temperature to avoid the degradation of ingredients caused by high temperature. The reduced pressure concentration process further reduces the solvent residue and improves the quality of the extract.
[0046] Preferably, the specific operating conditions of the supercritical CO2 extraction technology in step S2 include setting the pressure at 25-30 MPa, maintaining the temperature at 45-50°C, the CO2 flow rate at 10-20 liters / hour, the entrainer being ethanol, the volume ratio of ethanol to CO2 being 1:10 to 1:20, and the extraction time being 1-2 hours.
[0047] Supercritical CO2 extraction can efficiently and selectively extract fat-soluble active ingredients such as paclitaxel under specific pressure and temperature conditions, reducing the use and residue of organic solvents and improving product purity and safety. The optimization of operating conditions ensures the efficient extraction of active ingredients while protecting their chemical structure from being destroyed.
[0048] Preferably, the nano-processing in step S3 uses bifunctional nanoparticles, wherein the nanoparticles are composed of a chitosan matrix and a polyethylene glycol matrix, the polyethylene glycol chain end groups are amino groups, the deacetylation degree of chitosan is 80%-95%, and the particle surface is modified with folic acid or monoclonal antibodies.
[0049] The chitosan matrix provides good biocompatibility and targeting, while the polyethylene glycol (PEG) chain end modification amino group improves the stability of the drug and the circulation time in the blood. The modification of folic acid or monoclonal antibodies enables the nanoparticles to specifically bind to tumor cell surface receptors, improve the targeting and delivery efficiency of the drug, and enhance the anti-cancer effect.
[0050] Preferably, the microencapsulation treatment in step S3 adopts a multilayer coating technology, and the microencapsulation step includes first dissolving the active ingredient in an ethanol solution, then dripping the solution into a cross-linking agent containing a sodium alginate solution by a dropwise addition method to form primary microspheres, and then placing the obtained microspheres in a solution containing gelatin to coat the outer layer material, and finally freeze-drying to obtain microcapsules with a particle size of 100-500 nanometers.
[0051] The multi-layer coating technology provides an effective physical barrier to protect the active ingredients of the drug from the external environment, such as degradation by acidic gastric juice and digestive enzymes, ensuring the stability and sustained release of the drug. The multi-layer structure can also achieve effective release of the drug at the targeted site, further improving the efficacy and reducing systemic toxicity.
[0052] The present invention provides a group of innovative Chinese medicine preparations for enhancing anti-cancer therapeutic effects and a preparation process thereof.
[0053] It has the following beneficial effects:
[0054] 1. The present invention adopts an innovative technical solution combining a multi-component Chinese medicine formula with multi-layer coated microsphere technology, achieving multiple technical effects of multi-target anti-cancer, enhanced drug stability and improved bioavailability. Compared with the anti-cancer preparations that rely on a single Chinese medicine ingredient in the prior art, the present invention significantly improves the drug absorption rate and in vivo circulation time by scientifically combining twelve Chinese medicine ingredients and performing multi-layer coating treatment on the main active ingredients (such as astragalus polysaccharides, yew paclitaxel, etc.), thereby solving the shortcomings of existing single-ingredient preparations in anti-cancer treatment, such as limited effect, rapid drug metabolism, and high systemic toxicity, and provides a more effective treatment option with lower side effects for cancer patients.
[0055] 2. The present invention pre-treats the extracts of Gynostemma pentaphyllum, Ginseng, Atractylodes macrocephala and Ganoderma lucidum by enzymatic hydrolysis, significantly improving the release efficiency of polysaccharides and saponin components under mild conditions, and achieving the technical effect of retaining drug activity to the maximum extent. Compared with the extraction method that does not use enzymatic hydrolysis pretreatment in the prior art, the present invention effectively destroys the plant cell wall structure at a relatively low temperature (35-45°C) and neutral pH conditions (4.5-6.5) by introducing a specific combined enzymatic hydrolysis technology of cellulase and pectinase, greatly improving the extraction efficiency and the purity of the active ingredients, and solving the problems of incomplete extraction of active ingredients, unstable efficacy and uneven quality in traditional extraction processes.
[0056] 3. The present invention adopts a combined innovative extraction process of ultrasonic-assisted water extraction and supercritical CO2 extraction technology, which effectively improves the extraction efficiency of effective ingredients of traditional Chinese medicine and reduces solvent residue and energy consumption. Compared with the problems of high-temperature loss of active ingredients and large amount of solvent used in conventional water extraction or alcohol extraction methods in the prior art, the present invention uses ultrasonic-assisted extraction under mild conditions to quickly and efficiently release water-soluble components in cells; at the same time, combined with supercritical CO2 extraction technology, it is specifically used to extract fat-soluble active ingredients such as paclitaxel, to maximize the extraction effect and ensure the high purity of the ingredients, overcoming the shortcomings of low extraction efficiency, environmentally unfriendly process, and complex extract ingredients in the prior art.
[0057] 4. The present invention realizes precise targeted delivery and efficient utilization of drugs through the application of targeted nano-delivery technology, greatly improves the concentration of drugs at the tumor site, and significantly reduces the toxic side effects on normal tissues. Compared with the non-targeted delivery system in the prior art, the nanoparticle technology adopted in the present invention utilizes chitosan-polyethylene glycol (PEG) matrix, PEG chain end modified amino functional groups and specific targeting ligands (such as folic acid or monoclonal antibodies), which can bind to specific receptors on the surface of tumor cells to achieve efficient targeted delivery and long-term sustained release. This technical solution overcomes the systemic toxicity problems caused by uneven distribution, poor targeting, and high dosage of traditional drugs, significantly enhances the therapeutic effect and safety of anticancer drugs, and provides a new solution for precision medicine and personalized treatment.
