AI Article Synopsis
- The study evaluated the cytotoxic effects of four alkaloids (berberine, canadine, anonaine, and antioquine) on rat hepatocytes and two cell lines (HepG2 and HeLa) and found that berberine, anonaine, and antioquine were significantly cytotoxic, while canadine was not.
- Molecular modeling suggested that the structure of berberine may be responsible for its cytotoxic effects, highlighting its pharmacophoric features.
- Canadine showed significant antioxidant activity and low toxicity, indicating its potential as a novel antioxidant agent worth further research.
Article Abstract
The cytotoxic effects of four alkaloids, berberine, canadine, anonaine, and antioquine were evaluated using three different cell cultures, a primary culture (rat hepatocytes) and two cell lines (HepG2 and HeLa). Our results indicate that berberine, anonaine, and antioquine possess a significant the cytotoxic effect. In contrast, canadine does not possess cytotoxic effect at concentrations tested here. A molecular modeling study indicates that the quaternary nitrogen, the aromatic polycyclic and planar structure of berberine could be the pharmacophoric patron to produce the cytotoxic effect. In parallel our results demonstrated that canadine possess a significant antioxidant activity. Stereoelectronic aspects of this alkaloid were found to be closely related to those displayed by alpha-tocopherol and its water-soluble analogue trolox. The antioxidant activities of canadine, combined with its low-toxic effect, indicated that the potential of this alkaloid as a novel class of antioxidant agent is very interesting and deserves further research.

Canadine Platinum(IV) Complexes Targeting Epithelial-Mesenchymal Transition as Antiproliferative and Antimetastatic Agents.
J Med Chem

Institute of Biopharmaceutical Research, Liaocheng University, Liaocheng 252059, P.R. China.
Epithelial-mesenchymal transition (EMT) is a critical process for cancer progression, which is crucial in inhibiting the immunity in tumors and further boosting tumor metastasis. The suppression of EMT represents a promising strategy for inhibiting metastatic tumors. Herein, a series of new canadine platinum(IV) conjugates with potent antiproliferative and antimetastatic activities were developed, which activated by suppressing EMT and provoking immune response in tumors besides causing DNA injury.

Article Synopsis
- This study explores how Chinese herbs could potentially treat insomnia through techniques like data mining, network pharmacology, and molecular-docking validation.
- Researchers collected insomnia prescriptions from Qi Wang and used various databases to identify key medicinal herbs, active components, and relevant biological targets that contribute to the treatment.
- The analysis revealed 117 prescriptions with significant herbs, identified 6,417 differentially expressed genes connecting insomnia and healthy controls, and constructed a complex "transcription factor-miRNA-mRNA" network highlighting potential pathways involved in the therapeutic effects.
Article Synopsis
- * A total of 79 chemical constituents were identified, particularly phenylpropanoids, flavonoids, and alkaloids, with 13 active ingredients linked to nine key biological targets related to RA.
- * In laboratory tests, several components were shown to significantly inhibit inflammatory factor secretion in immune cells, indicating their potential as main active substances for RA treatment.
Tetrahydroberberine alleviates high-fat diet-induced hyperlipidemia in mice via augmenting lipoprotein assembly-induced clearance of low-density lipoprotein and intermediate-density lipoprotein.

The promotion of excess low-density lipoprotein (LDL) clearance stands as an effective clinical approach for treating hyperlipidemia. Tetrahydroberberine, a metabolite of berberine, exhibits superior bioavailability compared to berberine and demonstrates a pronounced hypolipidemic effect. Despite these characteristics, the impact of tetrahydroberberine on improving excessive LDL clearance in hyperlipidemia has remained unexplored.

Nonalcoholic fatty liver disease (NAFLD) has developed into the most common chronic liver disease and can lead to liver cancer. Our laboratory previously developed a novel prescription for NAFLD, "Eight Zhes Decoction" (EZD), which has shown good curative effects in clinical practice. However, the pharmacodynamic material basis and mechanism have not yet been revealed.
