Study of the influence of original multicomponent gels on the process of pathological scar formation using new methodological approach.
A new method of the quantitative macroscopic assessment of the process of a complex infected wound healing has been created. It was verified by example of the influence of original multicomponent gels consisting of cycloferon, amino acid glycine, glycyram (Glycyrrhizic acid ammonium salt), and vegetable oils on the process of infected wound healing and pathological scar formation. Simultaneously, the wound healing was monitored by the conventional histomorphological method. The proposed gels more effectively prevent the formation of pathological scars in comparison to reference preparation Contractubex.

As a traditional Chinese medicine ingredient with a long history of use, monoammonium glycyrrhizate has attracted significant attention in the field of natural medicine research in recent years due to its remarkable pharmacological activity and good safety. It demonstrates broad biological effects in anti-inflammatory, antiviral, immunomodulatory, and liver protection, especially showing significant potential in the prevention and treatment of liver diseases such as hepatitis.
This paper will systematically review the chemical structure and physicochemical properties of monoammonium glycyrrhizate (glycyrrhizate monoammonium), plant origin and extraction methods, pharmacological activity and mechanism of action, druggability evaluation and pharmacokinetic characteristics, and, combined with the current clinical application status, explore its future development prospects. It is hoped to provide theoretical basis and reference for in-depth research and clinical translation of monoammonium glycyrrhizate.
Glycyrrhizic acid monoammonium is the monoammonium salt form of glycyrrhizic acid, with a molecular formula of C42H65NO16 and a molecular weight of 822.9420. Glycyrrhetinic acid itself is a triterpene saponin, with a structure consisting of a glycyrrhetinic acid and two glucose residues connected by glycosidic bonds. Glycyrrhizate monoammonium forms monoammonium salts on the carboxyl group of glycyrrhizic acid, enhancing its water solubility and stability.
In terms of physicochemical properties, the LogP value of monoammonium glycyrrhizate is about 2.35, indicating moderate lipid solubility that facilitates cell membrane penetration. The polar surface area (TPSA) is 267.04 Ų, indicating that the molecule has strong polar groups, which is beneficial for water solubility. The measured water solubility is 0.1297 mg/mL, classified as a moderately water-soluble substance. The blood-brain barrier has low permeability, suggesting limited distribution in the central nervous system. The hERG channel inhibition test was negative, indicating a low risk of cardiotoxicity. The Ames mutagenic test result was 0.0, indicating a low genotoxicity risk.
The structural characteristics and physicochemical properties of monoammonium glycyrrhizate provide a basis for its pharmacokinetic behavior and efficacy in vivo, and also offer important parameter references for drug development.
The parent compound of glycyrrhizate monoammonium, glycyrrhizic acid, mainly comes from plants of the genus Licorice, especially licorice (Glycyrrhiza glabra L.), licorice (Glycyrrhiza uralensis Fisch.), and licorice (Glycyrrhiza inflata Batalin). As a traditional Chinese medicinal herb, licorice's roots and rhizomes are rich in glycyrrhizic acid and its derivatives, serving as the main raw material for preparing glycyrrhizic acid monoammonium.
The extraction process typically includes the following steps:
Modern extraction technologies also include ultrasound-assisted extraction, microwave-assisted extraction, and membrane separation techniques, aiming to improve extraction efficiency and purity, reduce production costs, and meet the demands of industrial manufacturing.
As a salt derivative of glycyrrhizic acid, glycyrrhizate monoammonium inherits and enhances multiple pharmacological activities of glycyrrhizic acid, especially showing outstanding performance in the field of liver diseases.
Monoammonium glycyrrhizate has significant anti-inflammatory activity and can reduce inflammatory responses by inhibiting the expression of inflammatory factors such as TNF-α, IL-6, and IL-1β. Its mechanism involves downregulating the nuclear factor κB (NF-κB) signaling pathway, reducing the release of pro-inflammatory cytokines, and alleviating tissue inflammatory damage.
Multiple studies have shown that monoammonium glycyrrhizate has inhibitory effects on hepatitis B virus (HBV), hepatitis C virus (HCV), and others. By interfering with the viral replication cycle and enhancing the host's immune response, it reduces viral load and promotes hepatocyte repair.
Monoammonium glycyrrhizate can enhance glutathione peroxidase (GPX1) activity, scavenge free radicals, and reduce cell damage caused by oxidative stress. At the same time, it regulates apoptosis regulatory proteins such as BCL2 and CASP3, protecting hepatocytes from damage.
Monoammonium glycyrrhizate can regulate immune cell function, promote immune tolerance, regulate the inflammatory microenvironment, and aid in liver tissue repair and regeneration.
The therapeutic effect of monoammonium glycyrrhizinate in diseases such as hepatitis depends on its regulation of multiple key molecular targets:
In summary, monoammonium glycyrrhizate achieves comprehensive regulation of liver inflammation, viral infection, and cellular damage through multi-target and multi-pathway synergistic effects.
The druggability parameters of monoammonium glycyrrhizate indicate that it has promising potential for drug development. With a molecular weight of 822.9420, it is relatively large, but its moderate LogP (2.35) and high polar surface area (TPSA 267.04) give it advantages in both lipid and water solubility, which is beneficial for distribution in vivo.
Its water solubility is 0.1297 mg/mL, making it suitable for both oral and injectable formulation development. The blood-brain barrier has low permeability, reducing the risk of central nervous system side effects. Negative hERG channel inhibition suggests good cardiac safety. Ames test is negative, indicating low genotoxicity risk.
Pharmacokinetic studies show that monoammonium glycyrrhizinate is well absorbed orally and is enriched in the liver, mainly metabolized by the liver and excreted via bile. Its half-life is moderate, maintaining effective plasma concentrations. The main metabolic products in the body are glycyrrhizic acid and its derivatives, which have certain biological activity.
However, monoammonium glycyrrhizate has a large molecular weight and strong polarity, which may limit its cell membrane penetration rate and affect bioavailability. In the future, drug formulation optimization and structural modification will be needed to enhance pharmacokinetic performance.
As a safe and effective natural medicinal ingredient, monoammonium glycyrrhizate has shown promising clinical application potential in the treatment of various liver diseases. Its anti-inflammatory, antiviral, and hepatoprotective effects provide new treatment approaches for diseases such as hepatitis, liver fibrosis, and fatty liver.
Currently, monoammonium glycyrrhizate has been widely used in traditional Chinese medicines, such as compound glycyrrhizin injection. Clinical data show it can significantly improve liver function indicators, reduce liver cell damage, and promote liver repair. At the same time, its good safety makes it suitable for long-term use.
Future research should focus on the following directions:
In summary, as a versatile natural medicinal ingredient, monoammonium glycyrrhizate has broad clinical application prospects and development potential.
