A new building block for electroactive organic materials? Synthesis, cyclic voltammetry, single crystal X-ray structure, and DFT treatment of a unique boron-based viologen.

A boronium-based paraquat analog undergoes reductions at more negative potentials than paraquat itself, making it a promising building block for electroactive materials.

Acellular invertebrate hemoglobins as model therapeutic oxygen carriers: unique redox potentials.

Natural acellular polymeric hemoglobins (Hb) provide oxygen transport and delivery within many terrestrial and marine invertebrate organisms. It has been our premise that these natural acellular Hbs may serve as models of therapeutic hemoglobin-based oxygen carriers (HBOC). Our attention has focused on the acellular Hb from the terrestrial invertebrate, Lumbricus terrestris (Lt), which possesses a unique hierarchical structure and a unique ability to function extracellularly without oxidative damage.

Determination of the formal reduction potential of Lumbricus terrestris hemoglobin using thin layer spectroelectrochemistry.

The formal reduction potential (Eo') of Lumbricus terrestris hemoglobin was determined using thin layer spectroelectrochemistry as 0.073 (+/-0.005) V vs Ag/AgCl (0.

Role of redox potential of hemoglobin-based oxygen carriers on methemoglobin reduction by plasma components.

A functional requirement for all hemoglobin-based oxygen carriers (HBOCs) is the maintenance of the heme-iron in the reduced state. This is necessary for the reversible binding/release of molecular oxygen and minimization of methemoglobin (Fe+3) formation. Acellular hemoglobins are especially susceptible to oxidation and denaturation.
