“…To overcome these limitations, several Pt( ii / iv ) coordination compounds have been designed and proposed as antitumor chemotherapeutic agents. 1–5 Extensive studies on unconventional Pt( ii / iv ) coordination compounds, such as riluzole, 6 2-(benzothiazol-2-yl)-phenolato, 7 1,10-phenanthroline derivatives, 8 (8-hydroxy)quinoline derivatives, 9,10 jatrorrhizine/berberine/cryptolepine derivatives, 11 2-(2-pyridyl)benzimidazole, 12 flurbiprofen and zaltoprofen, 13 bis(diisopropylphenyl)iminoacenaphthene, 14 boron dipyrromethene ligands, 15 rhodamine dithiocarbamate, 16 pyridinyl and pyridine ligands, 17 4-phenylbutyric acid, 18 aspirin, 19 coumarin, 20 combretastatin A4, 21 and heptamethine cyanines, 22 have yielded promising results.…”
