Lactiflorin, CAS number 1361049-59-3, is a monoterpene glycoside natural product isolated from plants of the Peony genus. As an organic heteropolycyclic compound, peony neoglycosides have a unique chemical structure and diverse biological activities, especially showing significant pharmacological effects in kidney protection and anti-inflammatory fields. In recent years, with in-depth research into the pharmacological mechanisms of natural products, peony neoglycosides have gradually become one of the hotspots in natural drug development due to their multi-target regulatory capabilities and superior safety. This paper will systematically review the chemical structure and physicochemical properties of peony neoglycosides, plant origin and extraction methods, pharmacological activity and mechanism of action, druggability evaluation and pharmacokinetic characteristics, and explore their clinical application prospects and research prospects, aiming to provide scientific basis for in-depth research and clinical translation of this compound.
The chemical formula of peony neoglycoside is C23H26O10, with a molecular weight of 462.4510. Its structure belongs to the monoterpene glycoside class, containing an organic heteropenate structure, specifically including bridging compounds, benzoates, cyclic ketones, and cyclochlorone functional groups. These structural features give it strong biological activity and good water solubility (0.4544), with a LogP value of 0.3479, indicating moderate lipophilicity, which is beneficial for distribution in the body but has a lower blood-brain barrier penetration ability. Its topological pole surface area (TPSA) is 140.98 Ų, indicating high polarity, which may affect membrane permeability and oral absorption. The hERG channel inhibition test results were negative, indicating that peony neoglycoside carries a relatively low cardiotoxicity risk; The Ames test value was 1.2, indicating low mutagenicity and good safety.
Peony neoglycosides are mainly found in plants of the Peony genus, especially in some traditional Chinese medicinal materials such as White Peony (Paeonia lactiflora Pall.), where their content is relatively abundant. Its extraction usually uses solvent extraction methods, with commonly used solvents including ethanol, water, or their mixed solvent systems. The extraction process generally includes the following steps:
In recent years, ultrasound-assisted extraction and microwave-assisted extraction technologies have also been applied to the extraction of peony neoglycosides, significantly improving extraction efficiency and purity. In addition, the application of modern separation technologies such as countercurrent chromatography and preparative HPLC provides effective means to obtain high-purity peony neoglycosides.
The pharmacological activity of peony neoglycosides mainly focuses on kidney protection and anti-inflammatory effects. Numerous in vivo and in vitro experiments have shown that peony neoglycoside can significantly reduce kidney damage, improve kidney function indicators, suppress inflammatory responses, and reduce tissue inflammatory damage.
Peony neoglycoside has shown protective effects in various kidney disease models, including acute kidney injury (AKI), chronic kidney disease (CKD), and diabetic nephropathy (DKD). Its mechanism of action involves antioxidant, anti-inflammatory, anti-fibrotic, and apoptosis regulation, among other aspects. For example, in the renal ischemia-reperfusion injury model, peony neoglycoside can reduce the formation of oxidative stress products, inhibit apoptosis of renal tubular epithelial cells, and promote renal tissue repair. In the diabetic nephropathy model, peony neoglycoside alleviates glomerular sclerosis and basement membrane thickening by regulating glycolipid metabolism and inhibiting inflammatory factor expression.
The anti-inflammatory effects of peony neoglycosides have been validated in various inflammation models. It can significantly downregulate the expression of pro-inflammatory cytokines such as IL-6 and TNF-α, inhibit activation of inflammatory signaling pathways, and reduce the release of inflammatory mediators. In vitro cell experiments showed that peony neoglycoside inhibits the activation of macrophages and other immune cells, reducing the expression of genes related to inflammation responses.
In addition, peony neoglycosides also show certain alleviating effects on disease models such as neuroinflammation, arthritis, and intestinal inflammation, suggesting broad anti-inflammatory potential.
The multi-target mechanism of peony neoglycosides forms the basis of its pharmacological activity. By regulating multiple signaling pathways and key molecules, peony neoglycosides exert their renal protective and anti-inflammatory effects.
Peony neoglycosides exert anti-inflammatory effects by inhibiting the IL-6/STAT3 and NF-κB signaling pathways, reducing the expression and release of pro-inflammatory factors. At the same time, peony neoglycosides regulate the TRPV1/TRPA1 channel, alleviating neuroinflammation and pain. Its inhibitory effect on CASP1 reduces the maturation of cytokine mediated by inflammasomes, further alleviating inflammatory responses.
Additionally, peony neoglycoside promotes antioxidant enzyme expression by regulating oxidative stress-related signaling pathways (such as Nrf2/ARE), protecting kidney cells from oxidative damage.
The druggability parameters of peony neoglycosides indicate that it has good potential for drug development. The molecular weight was moderate (462.45 Da), with a LogP value of 0.3479, indicating good hydrolipid balance, which is beneficial for distribution in the body but has low blood-brain barrier permeability, reducing the risk of adverse reactions to the central nervous system. A high TPSA value (140.98 Ų) suggests strong polarity, which may affect oral absorption, but bioavailability can be optimized through structural modification or formulation techniques.
In terms of safety, the hERG channel inhibition test was negative, indicating a low risk of cardiotoxicity; Ames trial results indicate that it has low mutagenicity and good genetic safety.
Pharmacokinetic studies show that peony neoglycosides are absorbed orally quickly, with a shorter peak plasma concentration, but bioavailability is limited by their polarity and water solubility. In the body, it is mainly metabolized by the liver, whose metabolic products are mostly water-soluble complexes that are easily excreted. Moderate half-life, suitable for daily administration. Future research needs to further clarify its metabolic enzyme system and drug interaction characteristics.
Peony neoglycosides, with their remarkable renal protective and anti-inflammatory activities, have broad clinical application prospects. Its potential therapeutic value in diabetic nephropathy, acute and chronic kidney injury, and various inflammatory diseases has attracted significant attention in drug development.
Future clinical research should focus on the following aspects:
Moreover, the structural diversity and good safety profile of peony neoglycosides provide a solid foundation for chemical modification and derivative development. In the future, structural optimization can enhance their efficacy and pharmacokinetic properties, promoting the transformation of natural products into innovative drugs.
Peony neoglycosides, a monoterpene glycoside derived from plants of the Peony genus, have a unique chemical structure and significant kidney protection and anti-inflammatory activities. Through multi-target and multi-signal pathway regulation, it exerts a wide range of pharmacological effects, offering good safety and druggability. With the ongoing advancement of pharmacological research on natural products, peony neoglycosides are expected to become a new candidate drug for treating kidney diseases and inflammation-related conditions. However, current research on its clinical application is still in its early stages, urgently requiring systematic pharmacokinetic, toxicological, and clinical trial data support. In the future, through multidisciplinary collaboration and technological innovation, the prospects for drug development and clinical translation of peony neoglycosides are broad and worthy of continued attention and in-depth exploration.
