This study explores the hepatoprotective effects of anacardic acid, a polyphenolic compound, in a rat model of acute liver injury induced by carbon tetrachloride (CCl₄). Given the increasing exposure to hepatotoxic xenobiotics from household, industrial, and agricultural chemicals, the development of effective and multi-targeted hepatoprotective agents is critical. The experiment was conducted in compliance with international animal ethics guidelines using Wistar rats. The research assessed various doses of anacardic acid administered both orally and intraperitoneally. Biochemical markers such as ALT, total protein, diene conjugates, and malondialdehyde (MDA) levels were measured to evaluate liver function and oxidative stress. The findings demonstrated that anacardic acid, particularly at a dose of 5 mg/kg administered intraperitoneally, significantly mitigated liver damage, restored biochemical parameters, and showed comparable efficacy to the standard hepatoprotective agent Karsil. These results suggest that anacardic acid possesses promising hepatoprotective properties and warrants further investigation as a potential therapeutic agent for hepatobiliary pathologies.

Abstract.

This study explores the hepatoprotective effects of anacardic acid, a polyphenolic

compound, in a rat model of acute liver injury induced by carbon tetrachloride (CCl₄). Given the

increasing exposure to hepatotoxic xenobiotics from household, industrial, and agricultural

chemicals, the development of effective and multi-targeted hepatoprotective agents is critical. The

experiment was conducted in compliance with international animal ethics guidelines using Wistar

rats. The research assessed various doses of anacardic acid administered both orally and

intraperitoneally. Biochemical markers such as ALT, total protein, diene conjugates, and

malondialdehyde (MDA) levels were measured to evaluate liver function and oxidative stress.

The findings demonstrated that anacardic acid, particularly at a dose of 5 mg/kg administered

intraperitoneally, significantly mitigated liver damage, restored biochemical parameters, and

showed comparable efficacy to the standard hepatoprotective agent Karsil. These results suggest

that anacardic acid possesses promising hepatoprotective properties and warrants further

investigation as a potential therapeutic agent for hepatobiliary pathologies.

Introduction.

Toxic liver damage is one of the most common etiological factors of hepatobiliary

pathology. It is associated with a significant increase in exposure to hepatotoxic xenobiotics,

including household, industrial, and agricultural chemicals. These exogenous factors not only

have specific mechanisms of action but also initiate a universal and potent endogenous

mechanism of hepatocyte damage in the form of oxidative stress [6]. The byproducts of this

process—aggressive and numerous reactive oxygen species (ROS)—lead to metabolic disorders,

membranopathies, functional impairments, mutations, accelerated apoptosis, and other forms of

cellular pathology.
Moreover, the multifactorial nature of toxic liver injury requires hepatoprotective agents to

provide multi-level protection, which is currently exhibited by only a limited number of

hepatoprotectors (e.g., Legalon, Silybor, Hepaton) [5]. A characteristic feature of modern

hepatoprotective agents is their origin from plant-based raw materials and their content of

polyphenolic compounds with antioxidant activity, such as flavonoids, flavolignans, cinnamic

acids, and others [2].

Materials and Methods.

The study was conducted on 240 mature male and female Wistar rats

weighing between 170–280 grams, in accordance with the international recommendations of the

European Convention for the Protection of Vertebrate Animals Used for Experimental and Other

Scientific Purposes [1]. Acute liver injury was induced by administering a 50% solution of carbon

tetrachloride (CCl₄) orally using a metal atraumatic probe [7].
In the experiments, the polyphenol

anacardine

under investigation was administered using oral

and intraperitoneal routes. The polyphenol was given orally at doses of 100, 300, and 500 mg/kg

twice daily for 12 days via gastric intubation. Additionally, it was administered intraperitoneally

at doses of 5, 15, and 25 mg/kg twice daily for 12 days.
It should be noted that the tested polyphenol was administered for 5 days prior to the introduction

of carbon tetrachloride, and then concurrently with it for 7 days—specifically, 1 hour before each

administration of CCl₄ [3,7].
The acute toxicity of the studied drug was assessed in accordance with methodological guidelines

for evaluating the general toxic effects of pharmacological agents. The experiment was conducted

based on the method of V.V. Gatsura. After 14 days of administering the investigated preparation

to animals with carbon tetrachloride-induced liver damage, sodium etaminal was injected

intraperitoneally at a dose of 40 mg/kg. The duration of sleep (in lateral position) was recorded in

minutes. Statistical results were processed and expressed as the arithmetic mean (M) and its

standard error (m).
Sodium etaminal and the studied polyphenolic compound

anacardin

were administered orally in

different doses (100, 300, and 500 mg/kg), as well as intraperitoneally in doses of 5, 15, and 125

mg/kg. The assessment was performed under acute toxic liver injury conditions induced by

carbon tetrachloride, and sodium etaminal was administered intraperitoneally at a dose of 40

mg/kg on the 14th day of compound administration [6]. Control animals received the same

volume of purified water.
According to the obtained results, compared to the control group, administration of anacardin led

to a significant and reliable reduction in sleep duration — particularly by 55.7% at a dose of 100

mg/kg.

Results

. The observed reduction in sodium etaminal-induced sleep duration during administration

of the test compounds is likely due to the hepatoprotective effect, which preserves the activity of

the hepatic microsomal system responsible for catalyzing biotransformation reactions of

xenobiotics, mediated by endoplasmic reticulum enzymes of the cytochrome P450 system.
Our study focused on determining the optimal therapeutic dose of the investigated compound that

would normalize altered biochemical parameters in hepatocytes under conditions of carbon

tetrachloride-induced liver damage. To achieve this goal, the contribution of the compound was

evaluated based on its ability to normalize reduced total protein levels and elevated ALT enzyme

activity, both of which are typical markers observed during hepatocellular cytolysis.
In our experiments, we first determined the levels of diene conjugates. The concentration of diene

conjugates was expressed in µmol/L. Carbon tetrachloride (CCl₄) poisoning disrupted all liver

functions: protein-synthetic activity (total protein content decreased by 27.2%), and severe

hepatocyte damage was observed through increases in serum diene conjugates and

malondialdehyde (MDA), a thiobarbituric acid-reactive substance (TBARS), by 41.2% and

175.1%, respectively, compared to the intact animal group.
When anacardine was administered orally at a dose of 100 mg/kg, levels of primary LPO products

(diene conjugates), final LPO products (TBARS, including MDA), and total protein in serum

remained significantly elevated compared to the intact control — 109.9%, 145.2%, and 88.5%,

respectively.
At a dose of 300 mg/kg, compared to 100 mg/kg, administration of anacardine resulted in a

significant reduction in serum diene conjugates and TBARS, with levels decreasing by 10.2% and

increasing by 20.6%, respectively, compared to control.
These results clearly show that CCl₄ intoxication disrupted all hepatic functions: protein synthesis

(with total protein decreasing by 26.2%), and caused severe hepatocellular damage, indicated by

increases in serum diene conjugates and MDA by 41.2% and 175.1%, respectively, compared to

the intact animal group.
General indicators, including survival rate, detailed biochemical analyses of blood serum and liver,

and data calculated based on the hepatoprotection coefficient, suggest that an intraperitoneal dose

of 5 mg/kg of anacardine may be recommended as an effective therapeutic dose.

Conclusion.

In carbon tetrachloride-induced hepatitis models, comparison of anacardine's

hepatoprotective effect with Karsil showed a reduction in serum diene conjugates (by 49%) and

TBARS levels in serum (by 36.4%) and liver (by 41.7%) compared to the control group.

Increased activity of ALT and decreased total protein levels, which are indicative of cytolysis,

were also normalized under the influence of the administered preparation.
