Biochem/physiol Actions

Elesclomol (STA-4783) is a copper (II)-chelating malonohydrazide derivative that exerts its in vitro and in vivo anticancer efficacy via reactive oxygen species (ROS)/oxidative stress & apoptosis induction in a Cu(II)-dependent manner (GI50 = 12 nM without vs. 129 nM with Cu2+ removal by TRIEN in K562 culture; typical conc. range 0.1-2 μM in cultures). Elesclomol chelates extracellular Cu(II) for mitochondria delivery, where upon Cu2+ reduction (to Cu+) & ROS generation, copper-free elesclomol then exits cells for continual Cu(II) shuttling and accumulation in mitochondria. In addition to Cu2+, elesclomol can also chelate Co2+ and Ni2+, but not Fe3+ or Zn2+.

MTH1 helps prevent misincorporation of ROS-damaged dNTPs into genomic DNA; however, there is little understanding of how MTH1 itself is regulated. Here, we report that MTH1 is regulated by polyubiquitination mediated by the E3 ligase Skp2. In melanoma cells, MTH1

Elesclomol is an anticancer drug that is currently undergoing clinical trials. Elesclomol forms a strong 1:1 complex with Cu(II) and may exert its anticancer activity through the induction of oxidative stress and/or its ability to transport copper into the cell.
