Monoclonal antibodies against metalloporphyrins. Specificity of interaction with structurally different metalloporphyrins

FEBS Letters, 1994
Monoclonal antibodies against Pd‐coproporphyrin I have been obtained. The antibody specificity for free as well as for conjugated Pd‐coproporphyrin I is characterized. Affinity constants are estimated for 3 monoclonal antibodies effectively interacting with free Pd‐coproporphyrin I.

Sunlight‐Induced Lipid Oxidation and Degradation of Edible Oil Mediated by Hemoglobin: Implications for Food System Sustainability

Food Science &Nutrition, Volume 14, Issue 10, October 2026.
Sunlight‐activated hemoglobin (Hb) functions as a robust natural biocatalyst that promotes the degradation of edible oils through a dual, synergistic pathway. Photo‐excitation of Hb triggers simultaneous energy transfer, generating singlet oxygen (1O2) and electron transfer, forming highly reactive ferryl (HbFe(IV)═O) species.

π-π Aggregation in metalloporphyrins: Causative factors

, 1976
The strength of aggregation in PdII, NiII, Zn II, and CdII metalloporphyrins is shown by n.m.r. spectroscopy to depend upon interaction of the metal ion with the porphyrin π-system; within a selected series of 2,4-disbustituted deuteroporphyrin-IX ...

Mass spectrometry of metalloporhyrins. 1. Mass spectra of octaethylporphines cobalt, nickel, copper

Тонкие химические технологии, 2010
Mass spectra of octaethylporphyrines of cobalt, nickel, copper with electron ionization were obtained. Molecular ions with isotope peaks and the peaks formed by separation hydrogen atoms from porhyrins core have maximum intensity.

Modular Metalloprotein Nanowires With Semiconductor‐Scale Conductivity and Tunable Redox Behavior

Small Structures, Volume 7, Issue 10, October 2026.
Conductive protein nanowires are built by aligning three different metalloproteins along an ultrastable filament scaffold. The resulting micrometer‐length nanowires reach conductivities of 1.75 S cm−1. Redox behavior is set by the metalloprotein chosen, while conductivity is governed by the spacing the scaffold imposes, making both independently ...

Deciphering Recent Developments in Photocatalysis of Multimetallic Metal–Organic Frameworks and Their Composite Heterojunctions

ChemSusChem, Volume 19, Issue 18, 28 September 2026.
This review explores the potential of multimetallic organic framework (MMOF) composites as photocatalysts. It demonstrates the impact of the composite architecture on the photocatalytic performance and existing challenges. The paper highlights heterojunction mechanisms and the role of each partner composites in degradation, CO2 reduction, H2 production,

Rationales for the Choice of Metals for Super‐Reduced Biological Metal Centers: Cobalt in Cobalamin Versus Nickel in F430

Chemistry – A European Journal, Volume 32, Issue 35, 19 September 2026.
DFT calculations on porphyrin, corrin, and corphin complexes of cobalt, rhodium, iron, manganese, or nickel, and QM/MM calculations on enzyme models, explore the factors controlling the availably of super‐reduced metal(I) states. True metal(I) states are seen in corrin only for cobalt, in corphin only for nickel, and not at all in porphyrin.

Clinically Important Features of Porphyrin and Heme Metabolism and the Porphyrias

Metabolites, 2014
Heme, like chlorophyll, is a primordial molecule and is one of the fundamental pigments of life. Disorders of normal heme synthesis may cause human diseases, including certain anemias (X-linked sideroblastic anemias) and porphyrias.
