Cobalt amine complexes and Ru265 interact with the DIME region of the mitochondrial calcium uniporter

We report our investigation into the MCU-inhibitory activity of Co3+ complexes in comparison to Ru265. These compounds reversibly inhibit the MCU with nanomolar potency. Mutagenesis studies and molecular docking simulations suggest that the complexes operate through interactions with the DIME motif of the MCU pore.

Automated summary

The investigation found that Co3+ complexes can inhibit MCU activity with nanomolar potency, and they operate through interactions with the DIME motif of the MCU pore.
