Five undescribed diterpenoid alkaloids tanguticulines A-E and two undescribed amide compounds 5-methoxy-N-Salicylanthranilic acid methyl ester and 3, 5-dimethoxy-4- hydroxycinnamamide-4-O-β-D-glucopyranoside, were isolated from the whole plant of Aconitum tanguticum (Maxim.) Stapf. Their structures were assigned by detailed analysis of MS and NMR spectroscopic data. Compounds 1 and 5 were evaluated for their antivirus activities against influenza a (H1N1) virus in vitro. Both of them showed obvious inhibitory effect on the cytopathic changes induced by H1N1, with IC values of 2.9 μg mL and 2.4 μg mL, respectively.

() is an important medicinal plant in the Aconitum genus that is known for its diterpenoid alkaloids, which exhibit significant pharmacological activity and toxicity, thus making it valuable for both medicinal use and as a biopesticide. Although the biosynthesis of terpenoids is well characterized, the potential gene regulatory role of microRNAs (miRNAs) in terpenoid biosynthesis in remains unclear, and further research is needed to explore this aspect in this species. In this study, miRNA sequencing was conducted to analyze the miRNA population and its targets in .

Neutrophil extracellular traps (NETs) formation is a key process in inflammatory diseases like gout, but the underlying molecular mechanisms remain incompletely understood. This study aimed to establish a model to examine the formation of NETs induced by monosodium urate (MSU) and phorbol 12-myristate 13-acetate (PMA) and to elucidate their molecular pathways. Laser confocal microscopy was used to visualize NET formation, while flow cytometry was employed to detect reactive oxygen species (ROS) production.

stands out among the Ranunculaceae family for its notable use as an ornamental and medicinal plant. Diterpenoid alkaloids (DAs), the characteristic compounds of , have been found to have effective analgesic and anti-inflammatory effects. Despite their medicinal potential, the toxicity of most DAs restricts the direct use of in traditional medicine, necessitating complex processing before use.

Paclitaxel is a widely used chemotherapeutic agent for the treatment of breast cancer (BC), including as a front-line treatment for triple-negative breast cancer (TNBC) patients. However, resistance to paclitaxel remains one of the major causes of death associated with treatment failure. Multiple studies have demonstrated that miRNAs play a role in paclitaxel resistance and are associated with both disease progression and metastasis.
