Introduction/Overview
Natural products, as an important treasure trove for drug discovery, play an irreplaceable role in the history of human disease treatment. Lily plants are widely used in traditional medicine, often used to nourish yin, moisten lungs, clear the heart and calm the mind. With the development of modern separation and identification techniques, a series of compounds with unique biological activities have been discovered from lilies, among which glycerol glucoside compounds have attracted much attention due to their diverse pharmacological activities. Wangyuzhi C is a representative glycerol glucoside isolated from plants of the lily genus, with a CAS number of 117591-85-2. Early research revealed its significant anti-inflammatory activity, and subsequent studies further found that in the oxidative stress-induced myocardial cell injury model, baicalin C can exert cardiomyocyte protection by protecting mitochondrial function, providing preliminary clues for its application in the field of cardiovascular and cerebrovascular diseases. In recent years, with the rise of bioinformatics tools such as network pharmacology and molecular docking, the anti-tumor potential of baicalin C, especially its application prospects in the treatment of cervical cancer, has begun to enter the research field. Its potential targets involve multiple key pathways such as apoptosis, proliferation, inflammation, and cell cycle regulation. This article aims to provide a systematic review of the chemical structure, plant origin, pharmacological activity, mechanism of action, pharmacological properties, and clinical application prospects of Wangyuxin C in diseases such as cervical cancer, in order to provide comprehensive scientific references for the in-depth research and development of this compound.
Chemical structure and physicochemical properties
Wangyuzhi C is a glycerol glucoside compound. Its basic chemical structure is composed of a glycerol molecule and a glucose molecule connected by glycosidic bonds. Specifically, the glucose group is usually attached to a specific hydroxyl position in glycerol, forming an O-glycosidic bond, which gives it a certain hydrophilicity and typical characteristics as a small molecule glycoside.
According to the provided pharmacological parameters, the molecular weight of Wang Baihe glycoside C is 416.3790 g/mol, which is a medium to small molecule. The calculated lipid water partition coefficient LogP value is -0.9403, indicating that the compound has good hydrophilicity and tends to be distributed in the aqueous phase. This characteristic is consistent with its topological polar surface area value, with a TPSA of up to 186.37 Å ², mainly attributed to the polar groups such as hydroxyl and ether oxygen atoms abundant in the molecule. The high TPSA and negative LogP values together explain its good water solubility, with a calculated value of 15.0053 mg/mL, indicating that it may have good solubility in water-based formulations.
However, the high polarity and TPSA also pose challenges to its biofilm permeability. The parameters show that its blood-brain barrier permeability is "low", which means that under conventional administration methods, it is difficult for baicalin C to effectively enter the central nervous system, which is an adverse factor for treating central nervous system diseases, but may also reduce its potential risk of side effects on the central nervous system. In the early screening of safety, Wang Baihe glycoside C did not show hERG potassium channel inhibitory activity ("No"), indicating a low risk of causing QT interval prolongation in the heart. Meanwhile, the Ames test result was 0.0, indicating that no mutagenicity was observed in this testing system, providing preliminary safety support for its further development. Overall, Wangyuxin C is a natural small molecule with strong water solubility, high polarity, specific biological activity, and good preliminary safety.
Plant sources and extraction methods
Wangyuxin C mainly comes from various plants in the lily family and lily genus. Lily plants are widely distributed worldwide, and many species such as Polygonum, Lilium, and Lilium not only have important value in horticulture, but also serve as the base plants for traditional Chinese medicine "lily". Wangyuxin C was initially isolated and identified from the bulbs of this genus of plants. Lily bulbs are rich in various chemical components such as starch, polysaccharides, alkaloids, saponins, and glycerol glucoside, and are the main parts for extracting active ingredients.
The extraction and separation of highly polar glycerol glucosides such as Wangyuzhi C usually follow the conventional process of natural product chemistry and are optimized for their physicochemical properties. The extraction method often uses solvent extraction:
1. Extract Methanol, ethanol, or ethanol water mixed solvents are commonly used for extraction, reflux, or ultrasound assisted extraction of dried and crushed lily bulbs. These polar solvents can effectively dissolve baicalin C. In recent years, green extraction techniques such as pressurized liquid extraction and microwave-assisted extraction may also be applied to improve extraction efficiency and selectivity.
2. Enrichment and Coarse Separation After the extract is concentrated under reduced pressure, the resulting paste is often subjected to gradient extraction using solvents such as petroleum ether, ethyl acetate, and n-butanol in sequence. Due to its strong hydrophilicity, Wangyuxin C is mainly enriched in the n-butanol extraction site or water layer.
3. Separation and purification Further purification relies on chromatographic techniques. Large pore adsorption resin column chromatography (such as D101, AB-8 type) is commonly used for sugar removal and preliminary enrichment. Subsequently, silica gel column chromatography, reverse phase silica gel column chromatography, dextran gel column chromatography, etc. were used for repeated separation. High performance liquid chromatography, especially preparative reverse phase high performance liquid chromatography, is the key final step in obtaining high-purity Wangyuxin C monomer. C18 chromatography columns are commonly used, with methanol water or acetonitrile water as the mobile phase for elution.
4. appraisal The isolated monomeric compound was structurally identified by spectroscopic methods such as nuclear magnetic resonance and mass spectrometry, confirming its presence as baicalin C.
The optimization of extraction processes usually focuses on factors such as solvent concentration, solid-liquid ratio, extraction temperature, and time to maximize the yield of the target compound.
Pharmacological activity research
The pharmacological activity research of Wangyuxin C has expanded from its initial anti-inflammatory effect to the fields of cell protection and potential anti-tumor effects, demonstrating various biological activities.
-
anti-inflammatory effect This is one of the earliest reported activities of Wangyuxin C. In classic in vitro inflammatory models such as lipopolysaccharide induced macrophages, baicalin C can dose dependently inhibit the excessive production of inflammatory mediators such as nitric oxide and prostaglandin E2, while downregulating the expression of inducible nitric oxide synthase and cyclooxygenase-2. These effects indicate its potential to alleviate acute inflammatory reactions.
-
Cardiomyocyte protective effect This is a highlight of the pharmacological research on Wangyuxin C. In the H9C2 rat myocardial cell oxidative stress injury model induced by hydrogen peroxide, baicalin C showed significant protective effects. It can improve cell survival rate and reduce leakage of lactate dehydrogenase. In depth research reveals that the core of its protective effect lies in Mitochondrial protection Wangyuxin C can stabilize mitochondrial membrane potential, reduce the accumulation of reactive oxygen species in cells, inhibit the initiation of mitochondrial pathway apoptosis, such as reducing the release of cytochrome C and activation of caspase. This provides important experimental evidence for its application in the prevention and treatment of cardiovascular diseases such as myocardial ischemia/reperfusion injury and heart failure.

Potential anti-tumor activity Although there are not sufficient in vitro and in vivo experimental reports directly targeting the anti-tumor effects of Wangyuzhi C, its potential in tumor prevention and treatment is worth paying attention to based on its known anti-inflammatory, antioxidant, and regulatory potential on apoptosis pathways, combined with network pharmacology predictions. Especially for cervical cancer, predictive models suggest that baicalin C may affect tumor progression by acting on multiple key targets. Its anti-inflammatory activity may help inhibit chronic inflammation of the tumor microenvironment closely related to the occurrence and development of cancer; And its ability to protect normal cell mitochondria and inhibit apoptosis may be transformed into a pro apoptotic effect in tumor cells by acting on specific targets, which requires further experimental verification.
Mechanism of action and molecular targets
The specific mechanism of action of Wangyuxin C has not been fully elucidated, but existing research combined with bioinformatics analysis has outlined a network that may exert its effects through multiple targets and pathways.
In Cardiomyocyte protection In the model, its mechanism mainly revolves around Mitochondrial homeostasis and apoptosis inhibition open. Wangyuzhi C, through its antioxidant properties, directly or indirectly clears excess ROS induced by H2O2 and maintains mitochondrial membrane potential integrity. The stable mitochondrial membrane prevents the release of apoptotic factors such as cytochrome C, thereby inhibiting the activation of downstream caspase cascade reactions and ultimately reducing cardiomyocyte apoptosis. This process may involve the regulation of Bcl-2 family proteins (such as inhibiting pro apoptotic protein Bax and promoting anti apoptotic protein Bcl-2), as well as the regulation of the p53 signaling pathway.
Regarding its presence cervical cancer Based on the provided relevant targets, the potential mechanism of action in can be reasonably speculated and network analyzed as follows:
* Inducing cell apoptosis Wangyuxin C may be upregulated TP53 The expression or activity of p53 activates its downstream pro apoptotic targets. Meanwhile, it may have an impact BCL2 The balance of family proteins (such as inhibiting anti apoptotic protein Bcl-2) promotes mitochondrial apoptosis pathway. Final effector CASP3 The activation of caspase-3 will execute the cell apoptosis program.
* Inhibit cell proliferation and survival signals Possible interference EGFR Mediated survival and proliferation signaling pathways. Meanwhile, regarding MAPK1 and MAPK8 The regulation of signaling pathways (which may inhibit abnormal activation of ERK and JNK) can affect cell proliferation, differentiation, and stress response.
* Anti inflammatory and immune regulation：NFKB1 It is a core transcription factor for inflammation and cell survival. Wangyuzhi C may downregulate its target genes by inhibiting the nuclear translocation of NF - κ B, such as PTGS2 The expression of prostaglandins can reduce the production of inflammatory mediators and alter the microenvironment conducive to tumor growth.
* Affects cell cycle and DNA repair：TOP1 It is a key enzyme for DNA replication and transcription, and also a target for certain chemotherapy drugs. Wangyuzhi C may interfere with tumor cell DNA metabolism by affecting TOP1 activity.CDKN2A The encoded p16 protein is an important cell cycle inhibitory protein, and baicalin C may induce cell cycle arrest by upregulating CDKN2A expression.
These targets do not exist in isolation, but form a complex network of interactions. For example, activation of p53 can regulate the Bcl-2 family and affect the NF - κ B pathway; EGFR signaling can intersect with the MAPK and NF - κ B pathways. Wangyuxin C may act as a "multi node regulator", slightly simultaneously regulating multiple links in this network, synergistically exerting a comprehensive effect of anti-inflammatory, pro apoptotic, and anti proliferative, thereby potentially inhibiting the growth of cervical cancer cells.It should be emphasized that most of these mechanism speculations are derived from bioinformatics analysis and extensions of known pharmacological effects, and the specific binding modes and signal transduction details need to be confirmed by rigorous molecular biology and cell biology experiments.
