Introduction/Overview
Isomucronulatol (CAS number: 64474-51-7) is a natural flavonoid product derived from the roots of traditional Chinese medicine Astragalus membranaceus. As a member of the flavonoid family, isoquercetin has gradually attracted attention in the field of pharmacology due to its unique chemical structure and biological activity. In recent years, with the deepening of research on the anti-inflammatory and anti-tumor mechanisms of natural products, isomorphol has shown potential value in regulating inflammatory responses and various disease-related signaling pathways, especially in the prevention and treatment of precancerous lesions such as adenomas.
This review will systematically summarize the chemical structure and physicochemical properties, plant sources, and extraction methods of isoquercetin, with a focus on its pharmacological activity and mechanism of action. Combined with modern pharmacological evaluation systems, it will explore its clinical application potential and future research directions, aiming to provide theoretical basis and research references for the drug development of this natural product.
Chemical structure and physicochemical properties
Yiwei convex sword leaf sedol belongs to the ether class of flavonoids, with a molecular formula of C17H18O6 and a molecular weight of 302.32. The structural characteristics of this compound include a typical flavonoid skeleton, containing multiple hydroxyl and methoxy substituents, which endow it with good polarity and biological activity basis. Its LogP value is 2.35, indicating that the molecule has moderate lipid solubility, which is beneficial for cell membrane penetration but not excessively hydrophobic, meeting the ideal lipid solubility range of most oral drugs.
The topological polar surface area (TPSA) is 69.17 Å ², and the number of hydrogen bond acceptors is 5, indicating its hydrophilicity and binding ability in intermolecular interactions. The low permeability of the blood-brain barrier suggests limited penetration ability in the central nervous system, which may reduce the risk of central toxicity. The evaluation of drug properties showed that isomyxorubicin had no hepatotoxicity, cardiotoxicity, or hERG channel inhibition, and the Ames mutagenicity test was negative, indicating high safety.
From the perspective of chemical synthesis, the complex flavonoid skeleton and multiple hydroxyl substituents of isoquercetin make its total synthesis difficult. Currently, it mainly relies on plant extraction and purification to obtain it.
Plant sources and extraction methods
Yiwei convex sword leaf saponin is mainly isolated from the root of Astragalus membranaceus. Huangqi, as a traditional Chinese medicinal herb, is widely used in various clinical formulas such as tonifying qi and stabilizing the surface, diuresis and reducing swelling. Its roots are rich in various flavonoids, among which isoquercetin is one of the important active ingredients.
The extraction process usually uses alcohol solvents (such as ethanol or methanol) for reflux extraction of dried Astragalus root powder, followed by multi-step separation and purification techniques such as liquid-liquid distribution and column chromatography (silica gel, reverse phase C18 column, etc.) to obtain high-purity isoamyl alcohol. High performance liquid chromatography (HPLC) and mass spectrometry (MS) techniques are commonly used for qualitative and quantitative analysis to ensure the quality and purity of extracts.
In recent years, the application of ultrasound assisted extraction and microwave-assisted extraction technologies has improved the extraction efficiency and yield of isoamyl alcohol, providing technical support for its large-scale production.
Pharmacological activity research
anti-inflammatory activity
Yiweitu Jianye Sha Chun showed significant anti-inflammatory activity in vitro experiments. Research has shown that this compound can inhibit the expression of IL-12 p40 subunits in macrophages induced by lipopolysaccharide (LPS). IL-12, as a pro-inflammatory cytokine, plays a key role in the pathogenesis of various inflammatory diseases. By reducing the production of IL-12, isomicrobiota can effectively regulate immune responses and alleviate inflammatory reactions.
In addition, there have been preliminary reports on the regulatory effects of isomyxorubicin on other inflammatory mediators such as TNF - α and IL-6, suggesting that it may exert anti-inflammatory effects through multi-target and multi pathway synergy.
Antitumor potential
Adenoma, as a precursor lesion of various malignant tumors, is closely related to the occurrence and development of multiple abnormal signaling pathways. Yiwei convex sword leaf saponin exhibits potential anti adenoma activity by regulating multiple molecular targets associated with adenomas, such as STAT3, SIRT1, NFE2L2, etc.
The STAT3 signaling pathway plays a crucial role in tumor cell proliferation, anti apoptosis, and immune escape. Yiwei convex sword leaf saponin may block the growth signal transduction of tumor cells by inhibiting the activation of STAT3. SIRT1, as a deacetylase, participates in cellular metabolism and stress response, and its regulation helps maintain cellular homeostasis. The effect of isoproterenol on SIRT1 may mediate its anti-tumor and anti-aging effects.
In addition, NFE2L2 (NRF2) is a core transcription factor for cellular antioxidant stress, and isomorphol enhances cellular antioxidant capacity, reduces oxidative stress damage, and blocks the malignant transformation process of adenomas by activating the NFE2L2 pathway.
Other pharmacological effects
Some studies have shown that isomyxorubicin may have multiple effects such as regulating lipid metabolism, protecting the liver, and immune regulation, but the relevant mechanisms still need to be further elucidated.
Mechanism of action and molecular targets
The pharmacological effects of Yiwei convex sword leaf saponin depend on its regulation of multiple molecular targets, especially in inflammation and tumor related signaling pathways.
- APP (amyloid precursor protein)APP plays a role in cellular signal transduction and inflammatory response, and isomyxorubicin may affect the inflammatory state and metabolic balance of cells by regulating APP expression.
- STAT3 (Signal Transduction and Transcription Activation Factor 3)STAT3 is a key node in pro-inflammatory and pro tumorigenic signaling, and isopiclone inhibits its phosphorylation and nuclear translocation, blocking downstream gene expression.
- ESR2 (estrogen receptor beta)ESR2 is involved in cell proliferation and differentiation, and isomorphol may affect hormone related cellular processes by regulating ESR2 activity.
- TYR (Tyrosinase)As a key enzyme in tyrosine metabolism, the regulation of TYR is related to the redox state of cells, and isoquercetin may regulate oxidative stress by affecting TYR.
- APEX1 (DNA repair enzyme)APEX1 is involved in DNA damage repair, and its regulation by isomicroconvex stegosol helps maintain genomic stability.
- ALOX15 and ALOX5 (lipoxygenase)Participate in the metabolism of fatty acids and the generation of inflammatory mediators, and isomicroconvex stegosol inhibits inflammatory reactions by regulating the activity of these enzymes.
- NFE2L2 (Nuclear Factor Red Blood Cell 2-Associated Factor 2)Activate the antioxidant defense system to protect cells from oxidative damage.
- NR1H4 (farnesyl ester X receptor)Regulating bile acid metabolism and inflammatory response, isomyxorubicin may regulate metabolic homeostasis through this target.
- SIRT1 (silencing information regulatory factor 2 related enzyme 1)Involved in cellular metabolism, inflammation, and aging processes, the activation of SIRT1 by isomorphol contributes to the realization of its multiple biological effects.
The multidimensional regulation of these targets demonstrates the potential of isomicroconvex clindamycin as a multi-target drug, particularly suitable for the treatment of complex diseases such as inflammatory diseases and tumors.
Evaluation of drug properties and pharmacokinetics
The pharmacological parameters of Yiwei convex Jianye Sha Chun show that it has good drug properties. The moderate molecular weight and LogP value ensure its good bioavailability and cell membrane penetration. The moderate number of TPSA and hydrogen bond receptors is beneficial for binding to target proteins.
In terms of safety, there is no hepatotoxicity, cardiotoxicity, or hERG channel inhibition, and the Ames test is negative, indicating a low risk of genetic toxicity and suitability for further drug development.
The low permeability of the blood-brain barrier suggests that isomorphol may mainly act on peripheral tissues, reducing the risk of central nervous system side effects.
At present, there is limited research on the pharmacokinetics of isoquercetin. Preliminary in vivo experiments suggest that its oral absorption is good, metabolism is stable, and it is mainly excreted through the liver metabolic pathway. Further systematic pharmacokinetic and toxicological studies are needed in the future to clarify its in vivo behavior and safe dosage range.
