Abstract
Background
Natural bioactive components derived from plant secondary metabolites have been pronounced as valuable alternatives for anticipating and subsiding hepatotoxic effects and its chronic complications based on experimental verification. The focus of this review is to elucidate the commonly used modern medicine for the treatment of liver disease and how major phytoconstituents have been tested for hepatoprotective activity, mechanism of action of some promising agents from natural sources, and clinical trial data for treating in patients with different liver diseases by the aid of natural phytoconstituents.
Main text
The review shows fifteen major isolated phytoconstituents, their biological sources, chemical structures, utilized plant parts, type of extracts used, hepatoprotective assay method, and their possible mechanism of action on the hepatoprotection. Nine promising hepatoprotective leads from natural sources with their chemistry and hepatoprotective mechanism are mentioned briefly. The review further includes the recent clinical trial studies of some hepatoprotective leads and their clinical outcome with different liver disease patients. Scientific studies revealed that antioxidant properties are the central mechanism for the phytoconstituents to subside different disease pathways by upsurging antioxidant defense system of cells, scavenging free radicals, down surging lipid peroxidation, improving anti-inflammatory potential, and further protecting the hepatic cell injury. In this review, we summarize recent development of natural product-based hepatoprotective leads and their curative potential for various sort of liver diseases. Furthermore, the usefulness of hit and lead molecules from natural sources for significant clinical benefit to discover new drug molecule and downsizing the problems of medication and chemical-induced hepatotoxic effects is extrapolated.
Conclusion
Further research are encouraged to elucidate the pharmacological principle of these natural-based chemical agents which will stimulate future pharmaceutical development of therapeutically beneficial hepatoprotective regimens.

Anti-inflammatory, analgesic, and acute toxicity evaluation of Litchi chinensis seed extract in albino rat
Litchi chinensis is a edible fruits of soapberry family commonly known as lychee; is traditionally used for the treatment of inflammation, headache, and body pain. The present study investigated the toxicity, anti-inflammatory, and analgesic activity of the ethanolic crude extract of Litchi chinensis to support its traditional use in its folk medicine and to screen the phytochemical constituents. 70% ethanolic extract of seeds of Litchi chinensis (LCSE) was prepared and preliminary phytochemical screening was performed. Acute toxicity of LCSE was carried out based on OECD guidelines 423. In vivo anti-inflammatory and analgesic effect of the extract was evaluated using carrageenan-induced paw edema and hot plate methods in Wistar albino rat's model. Results revealed that LCSE contains phenols, tannins, flavonoids, saponins, steroids, and alkaloids. LD50 values were found to be higher than 5000 mg/kg body weight; no any sign of toxicity, behavior changes, moribund, and mortality were observed in LCSE treated animals. Oral administration of LCSE at the dose of 150, 300, and 600 mg/kg produced a significant (p<0.05) dose-dependent inhibition in carrageenan-induced rat paw edema and hot plate. These results suggest that LCSE is non-toxic, and shows potent anti-inflammatory and analgesic activities over Wistar albino rats. These finding demonstrate that lychee seed extract acts as a good therapeutic candidate for the safe anti-inflammatory agents.</jats:p
A systematic review and meta-analysis on pharmacist-led interventions for the management of peptic ulcer disease.
Pharmacists are essential for developing pharmacotherapy plans, conducting clinical assessments, and overseeing drug monitoring. Their interventions help prevent medication errors and adverse drug events and enhance medication safety. This study aimed to systematically review pharmacist-led interventions for managing medication-related issues in patients receiving anti-ulcer treatments. A systematic review and meta-analysis was performed to explore four databases for studies published from 1904 up to June 2024. Nine studies were reviewed, including four retrospective, three case-control, one mixed-method, and one prospective pre-post study involving 34,099 participants. The average age of the patients was 61 years, and 50.23% were male. The study quality was high, with an average score of 6.22/7 on the modified Newcastle-Ottawa scale. All studies involved direct interactions between pharmacists and patients or physicians, and data were primarily collected from hospital electronic records. Pooled analysis demonstrated that pharmacist interventions significantly improved the rational use of anti-ulcer medications (OR: 4.5; 95% CI: 0.97 to 20.80; I2 = 89%, P = 0.05), as reported by studies. Pharmacist interventions have a significant impact on improving rational drug use, reducing costs and treatment duration, and enhancing appropriate medication use. These interventions also positively influenced medication adherence and the correction of irrational drug use
Antioxidant, Alpha-Amylase Inhibitory and Hypoglycemic Activity of Smallanthus sonchifolius Leaves from Nepal: An Integrated In Vitro, In Vivo, and In Silico Approach
In 2019, diabetes mellitus affected 9.3% of the global population and accounted for one in nine adult deaths. Plant-based antioxidants neutralize harmful free radicals, mitigate oxidative stress, and significantly prevent diabetes and its complications. This study evaluated the in vitro antioxidant, alpha-amylase inhibitory, in vivo oral hypoglycemic, and in silico antidiabetic potential of Smallanthus sonchifolius (S. sonchifolius) leaf extract. Mice (n = 25) were divided into five groups after a 16-h fast with access to water. The groups received distilled water (normal control), metformin (100 mg/kg, standard), or S. sonchifolius ethanolic extract at 100, 250, or 500 mg/kg to compare the antidiabetic potential of the extract with that of the control. Fasting blood glucose levels were measured in tail vein blood before the experiment and at 30, 60, and 120 min post-administration to evaluate the hypoglycemic activity of the extract and standard drug. The ethanolic extract exhibited dose-dependent alpha-amylase inhibition (IC50 value 0.136 mg/mL) and significant hypoglycemic effects, reducing blood glucose levels similar to those of the standard drugs voglibose and metformin. The maximum blood glucose reduction was 17.99% and 15.74% in the normal and glucose-loaded mice, respectively, at 500 mg/kg within 120 min. In silico analysis shows, polymatin B and chlorogenic acid demonstrating the highest binding affinity of −8.2 and −7.2 kcal/mol, respectively, in PPAR-γ (3G9E). Polymatin B and chlorogenic acid showed strong binding affinities of −7.3 and −7.5 kcal/mol, respectively, in alpha-amylase (4W93). These findings indicate that S. sonchifolius possesses significant hypoglycemic and antioxidant properties, suggesting its potential as an antidiabetic agent, warranting further clinical research
