Ferrocenyl-Triphenyltin Complexes as Lysosome-Targeted Imaging and Anticancer Agents.

Inorg Chem 2019 Jan 28;58(2):1710-1718. Epub 2018 Dec 28.

Institute of Anticancer Agents Development and Theranostic Application, The Key Laboratory of Life-Organic Analysis and Key Laboratory of Pharmaceutical Intermediates and Analysis of Natural Medicine, School of Chemistry and Chemical Engineering , Qufu Normal University , Qufu 273165 , China.

In this paper, two ferrocenyl-triphenyltin complexes were synthesized and characterized. Complex 2 is constructed as new multifunctional therapeutic platform for lysosome-targeted imaging and displayed much higher cytotoxicity than its analogue 1 by the introduction of a methyl group instead of a hydrogen atom in acylhydrazone. The cyclic voltammograms and reaction with GSH (glutathione) further confirmed that complex 1 has a reversible redox peak and can react with GSH, which indicate that complex 1 might lose its anticancer effect by undergoing reaction with GSH once it enters the cancer cell.

Overexpression of AtPCS1 in tobacco increases arsenic and arsenic plus cadmium accumulation and detoxification.

Planta 2016 Mar 13;243(3):605-22. Epub 2015 Nov 13.

Department of Environmental Biology, "Sapienza" University of Rome, Rome, Italy.

Main Conclusion: The heterologous expression of AtPCS1 in tobacco plants exposed to arsenic plus cadmium enhances phytochelatin levels, root As/Cd accumulation and pollutants detoxification, but does not prevent root cyto-histological damages. High phytochelatin (PC) levels may be involved in accumulation and detoxification of both cadmium (Cd) and arsenic (As) in numerous plants. Although polluted environments are frequently characterized by As and Cd coexistence, how increased PC levels affect the adaptation of the entire plant and the response of its cells/tissues to a combined contamination by As and Cd needs investigation.
