AI Article Synopsis
- * Through network pharmacology, researchers identified 13 active compounds in SGF and 71 potential target proteins, with oxidative stress, inflammation, and apoptosis playing key roles in lead poisoning treatment.
- * Experimental findings demonstrated that SGF treatment not only reduced kidney damage in lead-exposed rats but also inhibited critical proteins in the NF-κB/MAPK signaling pathway, underscoring SGF's effectiveness against lead-induced nephrotoxicity.
Article Abstract
Lead (Pb) is a major environmental pollutant that can cause nephrotoxicity, hepatotoxicity, encephalopathy, and even death. Smilax glabra Roxb. has been used to treat heavy metal poisoning in China for over 500 years. We hypothesized that the Smilax glabra flavonoid extract (SGF) can ameliorate lead poisoning and investigated the possible mechanisms using network pharmacology. In total, 13 active compounds of Smilax glabra Roxb. and 71 overlapping potential targets were identified. The drug-compound-target-disease network analysis revealed that oxidative stress, inflammation, and apoptosis were mainly involved in the treatment of lead poisoning. Gene Ontology (GO) enrichment analysis showed that the biological processes involved in the therapeutic effect of Smilax glabra Roxb. against lead poisoning included biological processes, cellular components, and molecular functions. Additionally, 112 Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment pathways were obtained with the nuclear factor kappa B (NF-κB) and mitogen-activated protein kinase (MAPK) signaling pathways showing strong associations with lead poisoning by KEGG enrichment. The results of target pathway analysis showed that NF-κB was the most relevant gene involved in the therapeutic effect of Smilax glabra Roxb. against lead poisoning and was closely related to the MAPK signaling pathway. In vivo experiments confirmed that SGF treatment alleviated the pathological damage caused by lead-induced nephrotoxicity in weaning rats. Furthermore, SGF treatment markedly inhibited the expression of key proteins involved in the NF-κB/MAPK signaling pathway, highlighting the strong therapeutic effect of SGF against lead-induced nephrotoxicity. Results from network pharmacology and experimental verification indicated that SGF mitigated Pb-induced nephrotoxicity by downregulating the NF-κB/MAPK signaling pathway.

Under the guidance of HPLC-DAD analysis, ten new chromones featuring a rare [6,6]-spiroketal moiety, namely chaetovirexylariones A-J (-), together with two known congeners (-), were isolated from coculture of the endophytic fungi and , from the rhizome of the medicinal plant Roxb. Their structures were elucidated via a combination of NMR and HRESIMS data, and the absolute configurations of - were determined by the chemical conversion and single-crystal X-ray diffraction (Cu Kα) experiments, as well as the comparison of the experimental and calculated electronic circular dichroism (ECD) data. Compound is the first report as a racemate of this type of natural product.

Article Synopsis
- Acetaminophen (APAP) overdose can lead to acute liver injury (ALI), and current treatments for this condition are limited; however, astilbin, a compound from Smilax glabra with antioxidant properties, shows promise in protecting against ALI.
- In a study with mice, astilbin was administered prior to APAP exposure, and the results indicated that it helped reduce ALI by altering gut microbiota and increasing beneficial metabolites like hydroxytyrosol.
- Further analysis revealed that hydroxytyrosol also provided protective effects by reducing oxidative stress and inflammation in the liver, demonstrating that astilbin promotes liver health through its interaction with gut microbes and metabolites.
