WebThe thread-like morphological features of functional mitochondria become fragmented when levels of reactive oxygen species (ROS) increase, and ROS can be generated via Fenton-like chemistry in the presence of ferrous iron (Fe2+). Endolysosomes are central to iron trafficking in cells and contain readily releasable Fe2+ stores. WebA class of so-called POP ligands (Xanthos, NiXantphos, DPEphos) are of a great interest to the coordination chemistry due to their wide P-M-P bite angles and ability to show either κ2- or κ3-binding modes. Such κ2–κ3-rearrangement is valuable for catalytic application and internal stabilization of intermediates. To widen the …
