CHARACTERIZATION OF A MODIFIED GRAPHITE ELECTRODE OBTAINED BY HEMIN ELECTROPOLYMERISATION

Studia Universitatis Babes-Bolyai Chemia, 2015
A new modified electrode (G/polyHm) was obtained by electropolymerisation of iron (III) protoporphyrin (IX) (hemin, Hm) at the surface of a graphite electrode (G), by repetitive scanning the potential between -0.85 and 0 V vs. Ag/AgCl,KClsat.

N‐methylation of histidine to tune tautomeric preferences in histidine‐heme coordination and enzyme‐mimetic catalysis

Smart Molecules
Enzymes with active sites involving histidine selectively utilize either the δ‐ or ε‐nitrogen atom (Nδ or Nε) of the histidine imidazole for catalysis.

Hemin enhances the 5-aminolevulinic acid-photodynamic therapy effect through the changes of cellular iron homeostasis

Photodiagnosis and Photodynamic Therapy
Background: Photodynamic therapy (PDT) has been utilized as a promising alternative cancer treatment due to its minimum invasiveness over the years. Exogenous 5-aminolevulinic acid (ALA) triggers protoporphyrin IX (PpIX) accumulation, which happens in ...

Resolving the effects of albumin glycation using the quartz crystal microbalance

MATEC Web of Conferences, 2013
Both lysine and arginine residues are particularly important at receptor sites for binding anionic ligands. These receptor sites may become compromised via non-enzymatic glycation.

Hemin-induced transient senescence via DNA damage response: a neuroprotective mechanism against ferroptosis in intracerebral hemorrhage

Communications Biology
Intracerebral hemorrhage (ICH) poses acute fatality and long-term neurological risks, in part due to hemin and iron accumulation from hemoglobin breakdown.

Exogenous Hemin Increases the Yield, Phenolic Compound Content, and Antioxidant Enzyme Activity of Dragon Fruit during the High-Temperature Period

Agronomy
Dragon fruits have abundant nutritional and antioxidant properties. High temperatures limit the growth and production of dragon fruits. Hemin can effectively alleviate abiotic stress in plants.
