Thin layer chromatography (TLC) was performed using silica gel 60 F-254 (Merck)
plates with detection of spots being achieved by exposure to UV light. Column chromatography was done using Silica gel 60-200 µm (VWR). Eluent mixtures are expressed as volume to volume (v/v) ratios. 1 H and 13 C NMR spectra were measured on Bruker Avance III HD 400 MHz or Bruker Avance Neo 500 MHz spectrometers using the signal of the deuterated solvent as an internal standard. 101 The chemical shifts This ICP-MS enables working in different resolution modes (LR=400, MR=4000 and HR=10000) for a better discrimination between elements of interest and interferences. 102 For the metabolic studies Seahorse XFe96 Analyser by Agilent Technologies was used.
