AbstractOrganometallic platinum(II) terpyridine complexes with a caffeine derived N-heterocyclic carbene (NHC) ligand were investigated as possible anti-cancer drugs in comparison to analogs, which contain N-coordinated theobromine. In general the carbene complexes displayed significantly higher biological activity than the theobromine analogs. In particular, the caffeine derived organometallic platinum(II) complex [PtII(2,2′:6′,2″-terpyridine) (1,3,7,9-tetramethylxanthine-8-ylidene)](PF6)2 (1) displayed very promising cytotoxic activity towards several cancer cell lines, and showed in-vitro anti-angiogenic effects at sub-cytotoxic concentrations. Moreover, it induced neural differentiation-like morphological changes in breast adenocarcinoma (MCF-7) cells.
