ABSTRACT

Selected gold complexes have been regarded as promising anti-cancer agents because they can bind with protein targets containing thiol or selenol moieties, but their clinical applications were hindered by the unbiased binding towards off-target thiol-proteins. Recently, a novel gold(III)-hydride complex (abbreviated as 1) with visible light-induced thiol reactivity has been reported as potent photo-activated anticancer agents (Angew. Chem. Int. Ed., 2020, 132, 11139). To explore new strategies to stimuli this potential antitumor drug, the effect of oriented external electric fields (OEEFs) on its geometric structure, electronic properties, and chemical reactivity was systematically investigated. Results reveal that imposing external electric fields along the Au-H bond of 1 can effectively activate this bond, which is conducive to its dissociation and the binding of Au site to potential targets. Hence, this study provides a new OEEF-strategy to activate this reported gold(III)-hydride, revealing its potential application in electrochemical therapy. We anticipate this work could promote the development of more electric field-activated anticancer agents. However, further experimental research should be conducted to verify the conclusions obtained in this work.

ABSTRACT

BACKGROUND: Non-alcoholic fatty liver disease (NAFLD)-related cirrhosis is mainly caused by NAFLD by causing inflammation which leads to fibrosis. The role of leptin in NAFLD-related cirrhosis has been rarely reported. CASE SUMMARY: This study presents the case of a 65-year-old male patient who was referred to The First Affiliated Hospital of Guangxi University of Chinese Medicine, Guangxi, China, for diagnosis and treatment for liver cirrhosis. Initially, the cause of liver cirrhosis was unknown. After radiology, laboratory examination, pathological results and analysis of the patient's signs and symptoms, the case was finally diagnosed with final NAFLD-related cirrhosis. Although this study reports a single case, the findings might expand the understanding of leptin's role in NAFLD-related cirrhosis and might provide a basis for the clinical diagnostic criteria, pathological features and treatment of NAFLD-related cirrhosis. CONCLUSION: Although the occurrence of marasmus NAFLD-related cirrhosis is rare, it needs to be distinguished from other liver diseases, including viral hepatitis, drug-induced liver disease, Wilson's disease and autoimmune liver disease. Aggressive treatment is needed to prevent the progression of NAFLD-related cirrhosis.
