Graphical Abstract

No trafficking: The antitumor-active trans-platinum/thiazole complex trans-PtTz demonstrated high reactivity to the transcription factor Sp1, which is overexpressed in tumor cells. The binding of trans-PtTz disrupts the DNA interaction with Sp1 in vitro and prevents the protein trafficking from the cytoplasm into the nucleus (see picture).
