Introduction/Overview
Anwuligan, CAS number 107534-93-0, is a typical lignan natural product, mainly isolated from traditional Chinese medicinal materials such as Schisandra chinensis. As a natural compound with multiple biological activities, pentalipidin demonstrates significant pharmacological effects in antioxidant, anti-inflammatory, and metabolic regulation, attracting widespread attention in pharmacology and natural medicinal chemistry in recent years. Especially in adjunctive therapy for liver dysfunction and chemical liver injury, ampentadanin has shown good protective effects. Moreover, recent research suggests that amnpentalipin may participate in the pathological mechanisms of neurological diseases such as migraine disorders by regulating various molecular targets, offering new ideas and potential value for its clinical application. This paper aims to systematically review the chemical structure, plant origin, pharmacological activity, mechanism of action, druggability evaluation, and future clinical application prospects of pentalipidin, aiming to provide comprehensive and in-depth reference materials for researchers in related fields.
Chemical structure and physicochemical properties
Anpentadin belongs to the lignan class of compounds with the molecular formula C20H24O4 and a molecular weight of 328.40. Its structural features are mainly the typical diphenylpropane backbone, featuring multiple hydroxyl substitutions and methoxy groups, which impart excellent antioxidant activity. In terms of physicochemical properties, the LogP value of pentadipidin is about 4.21, indicating good lipid solubility, which is beneficial for cell membrane penetration and bioavailability. The topological pole surface area (TPSA) is 55.12 Ų, and the number of hydrogen bond receptors is 4, indicating moderate polarity and hydrogen bond binding capability in drug design.
Blood-brain barrier (BBB) permeability assessment showed that pentadanin has a lower BBB penetration capacity, which may limit its direct role in central nervous system diseases but also reduces the risk of potential CNS toxicity. In terms of toxicological evaluation, pentafatin showed no hepatotoxicity, cardiotoxicity, or hERG channel inhibitory effects, demonstrating a good safety profile. Ames-induced mutagenic test data are not yet clear, and further tests are needed to verify its genotoxicity risk.
Plant Origins and Extraction Methods
Anphthadanin is mainly isolated from Schisandra chinensis. Schisandra belongs to the Schisandaceae family, widely distributed in Northeast and North China, as well as the Korean Peninsula. It has long been used as a traditional Chinese medicine to regulate liver function, enhance immunity, and combat fatigue. Besides schisandra, some plants containing lignans can also detect pentadyne, but at lower levels.
The extraction process typically uses organic solvent extraction combined with column chromatography for separation and purification. The specific process includes:
1. Use ethanol or methanol as extractants to extract dried Schisandra fruit by reflux extraction;
2. Concentrate the extract by vacuum reduction;
3. Separation and purification using silica gel column chromatography and reversed-phase high-performance liquid chromatography (RP-HPLC);
4. Finally, the structure and purity are confirmed using technologies such as nuclear magnetic resonance (NMR) and mass spectrometry (MS).
In recent years, the application of ultrasound-assisted extraction and microwave-assisted extraction technologies has improved the extraction efficiency and purity of pentadan, and is more in line with green chemical principles.
Pharmacological activity research
Antioxidant effects
Anpentalipidin exhibits significant antioxidant activity, effectively scavenging free radicals and inhibiting lipid peroxidation. In vitro DPPH radical scavenging experiments and cell models, ampentalipin significantly reduced oxidative stress indicators and enhanced intracellular antioxidant enzyme activity (such as superoxide dismutase SOD and glutathione peroxidase GSH-Px). Its antioxidant mechanism is closely related to the electron donor capacity of polyhydroxyl and methoxy groups in its structure.
Anti-inflammatory effects
Multiple in vivo and in vitro experiments have shown that pentalipidin can inhibit the production and release of inflammatory mediators. By downregulating the NF-κB signaling pathway, it reduces the expression of pro-inflammatory cytokines (such as TNF-α, IL-1β, IL-6), thereby alleviating inflammatory responses. In mouse models, ampentalipin significantly alleviated inflammatory liver injury and tissue edema, demonstrating good anti-inflammatory effects.
Regulates metabolic functions
Anpentadanin regulates liver lipid metabolism and can improve hepatic steatosis and lipid accumulation. By activating the AMPK signaling pathway, it promotes fatty acid oxidation, inhibits lipid synthesis, and reduces hepatocyte fat deposition. Additionally, pentadipin affects glucose metabolism and demonstrates potential anti-diabetic effects.
Liver-protective effects
Anpentadanin has shown significant protective effects in various liver injury models. In chemical liver injury (such as carbon tetrachloride and alcohol-induced models), pentadipin can lower serum transaminase (ALT, AST) levels, alleviate hepatocyte necrosis and inflammatory infiltration, and promote liver tissue repair. Its hepatoprotective effects are mainly attributed to multiple mechanisms including antioxidant, anti-inflammatory, and regulation of apoptosis.
Neuroprotection and migraine-related research
Although pentalipidin has low blood-brain barrier permeability, it may have adjunctive therapeutic potential for migraine disorders by regulating the peripheral nervous system and inflammatory responses. Related studies indicate that ampentalipidin acts on multiple targets including ALOX15, BCHE, ACHE, EDNRA, DRD1, ADRA1A, TAAR1, EP300, and P2RX7, regulating inflammation, neurotransmitter metabolism, and vascular tone, thereby alleviating migraine symptoms.
Mechanism of action and molecular targets
The multi-target mechanism of pentafatin is the basis of its pharmacological activity. The main targets and related mechanisms are as follows:
- ALOX15 (lipoxygenase 15): Involved in lipid peroxidation and the generation of inflammatory mediators, Anpentalipin reduces the production of inflammatory mediators such as leukotrienes by inhibiting ALOX15 activity, thereby alleviating inflammatory responses.
- BCHE (Butyrylcholinesterase) and ACHE (Acetylcholinesterase): Regulating cholinergic neurotransmission, pentalipidin affects the metabolism of the neurotransmitter acetylcholine by modulating the activity of these enzymes, which may improve neurological dysfunction.
- EDNRA (endothelin receptor type A): Regulates vasoconstriction; pentalipin may antagonize EDNRA, reduce vasospasm, and alleviate migraine-related vascular abnormalities.
- DRD1 (dopamine D1 receptor) and ADRA1A (α1 adrenergic receptor): involved in neurotransmitter signaling, pentalipidin regulates the activity of these receptors, affecting nerve excitation and vascular tone.
- TAAR1 (trace amine-related receptor 1): regulates neurotransmitter release; pentalipidin may improve nervous system function by activating or modulating TAAR1.
- EP300 (transcription co-activator p300): regulates gene expression. Anpentalipin may affect inflammation- and metabolism-related gene expression by modulating EP300-mediated transcriptional activity.
- P2RX7 (P2X7 receptor): Involved in inflammatory responses and apoptosis, pentalipidin helps reduce inflammation and cellular damage by regulating P2RX7.
Overall, Anpentadin regulates inflammatory responses, neurotransmitter metabolism, and vascular function through multi-target and multi-pathway synergistic effects, exerting its broad pharmacological effects.
Druggability evaluation and pharmacokinetics
The druggability evaluation of pentalipidin shows it has good potential for drug development. The molecular weight of 328.4 meets the Lipinski rule, and the LogP of 4.21 is moderate, indicating good membrane permeability and in vivo distribution characteristics. TPSA is 55.12 Ų, indicating moderate polarity and favorable for oral absorption.
Toxicological data indicate that pentafatin does not show significant hepatotoxicity, cardiotoxicity, or hERG channel inhibition, and is relatively safe. However, the lower permeability of the blood-brain barrier limits its direct role in central nervous system diseases but also reduces the risk of adverse reactions.
In terms of pharmacokinetics, current research is relatively limited. In vivo animal experiments show that pentadipin is absorbed orally relatively quickly, has a moderate plasma half-life, and is mainly metabolized by the liver, with excretion primarily via bile and urine. In the future, further systematic research on pharmacokinetics and metabolic kinetics is needed to clarify their in vivo behavior and metabolic activity products.
Prospects and outlooks for clinical applications
Based on the multiple pharmacological activities of Anpentaditin, especially its significant effects in liver protection, anti-inflammation, and metabolic regulation, it holds broad application prospects in adjunctive treatment of liver dysfunction, chemical liver injury, and metabolic syndrome. In recent years, with deeper understanding of migraine pathogenesis, Anpentazin has gained new ideas for treating migraine and other neurological diseases by regulating multiple targets to participate in neuroinflammation and vascular function regulation.
Future research focuses should include:
1. Systematic evaluation of the efficacy and safety of pentadipin in neurological diseases, especially its clinical efficacy verification for migraine;
2. Optimize extraction and synthesis processes to increase the yield and purity of Anpentalipin, and reduce production costs;
3. In-depth analysis of its molecular mechanisms to uncover more potential targets and signaling pathways;
4. Conduct pharmacokinetic, toxicological, and preclinical safety evaluations to lay the foundation for clinical trials;
5. Explore formulation development for pentalipidin, such as nanocarriers and sustained-release formulations, to improve its bioavailability and targeting.
In summary, pentafatin is a natural lignan compound with multi-target effects and possesses good pharmacological activity and safety, making it expected to become an important candidate for the treatment of liver and neurological diseases in the future.
