Porphyromonas gingivalis is a keystone bacterial pathogen of chronic periodontitis. P. gingivalis is unable to synthesise the porphyrin macrocycle and relies on exogenous porphyrin, including haem or haem biosynthesis intermediates from host sources. We show that under the iron-limited conditions prevailing in tissue environments, P. gingivalis expresses a haemophore-like protein, HusA, to mediate the uptake of essential porphyrin and support pathogen survival within epithelial cells. The structure of HusA, together with titration studies, mutagenesis and in silico docking, show that haem binds in a hydrophobic groove on the alpha-helical structure without the typical iron coordination seen in other haemophores. This mode of interaction allows HusA to bind to a variety of abiotic and metal-free porphyrins with higher affinities than to haem. We exploit this unusual porphyrin-binding activity of HusA to target a prototypic deuteroporphyrin-metronidazole conjugate with restricted antimicrobial specificity in a Trojan horse strategy that effectively kills intracellular P. gingivalis.

The doxorubicin – hemin interaction was studied by absorption and emission spectroscopy. The absorption spectra outline two processes, in function of the concentration range of hemin. The fluorescence emission of doxorubicin shows a pronounced hypochromic effect in presence of hemin. The best fit was obtained using an (1:1) and (1:2) interaction for both methods. The doxorubicin – hematoporphyrin and doxorubicin – FeIII systems were also investigated in similar experimental conditions, in order to outline the possible binding sites involved in the interaction. The quenching effect of hematoporphyrin is smaller than that of hemin, the binding parameters indicated an (1:1) interaction and are smaller than the corresponding values for hemin. For the doxorubicin – FeIII system, the association constants for (1:1) and (1:2) complexes are in a reasonable agreement in both methods used. Our results are consistent with a two site binding model, where the Fe III ions of hemin are involved to a higher extent than the planar porphyrin moiety in the hemin – doxorubicin interaction.

Therefore, this conceptually novel strategy might open impressive avenues to establish green and sustainable chemistry platforms. In my other articles, you can also check out more blogs about 16009-13-5

Complexation of iron(II) protoporphyrin IX (Fe2+PP) into a genetically engineered heme pocket on recombinant human serum albumin (rHSA) creates an artificial hemoprotein which can bind O2 reversibly at room temperature. Here we highlight a crucial role of a basic amino acid triad the entrance of the heme pocket in rHSA (Arg-114, His-146, Lys-190) for O 2 and CO binding to the prosthetic Fe2+PP group. Replacing His-146 and/or Lys-190 with Arg resolved the structured heterogeneity of the possible two complexing modes of the porphyrin and afforded a single O 2 and CO binding affinity. Resonance Raman spectra show only one geometry of the axial His coordination to the central ferrous ion of the Fe 2+PP.

Future efforts will undeniably focus on the diversification of the new catalytic transformations. We’ll also look at important developments of the role of 16009-13-5, and how the biochemistry of the body works.Electric Literature of 16009-13-5

An antimicrobial agent for the biocidal finish of polymers based on biocides is described, whose molecules have at least one nitrogen atom with a free electron pair. In order to achieve an extensive insolubility without loss of the biocidal effect, it is proposed that the biocide is coordinatively bound to a metal complex via the free electron pair of the nitrogen atom.

Glucocorticoids are used during prostate cancer (PCa) treatment. However, they may also have the potential to drive castration resistant prostate cancer (CRPC) growth via the glucocorticoid receptor (GR). Given the association between inflammation and PCa, and the anti-inflammatory role of heme oxygenase 1 (HO-1), we aimed at identifying the molecular processes governed by the interaction between HO-1 and GR. PCa-derived cell lines were treated with Hemin, Dexamethasone (Dex), or both. We studied GR gene expression by RTqPCR, protein expression by Western Blot, transcriptional activity using reporter assays, and nuclear translocation by confocal microscopy. We also evaluated the expression of HO-1, FKBP51, and FKBP52 by Western Blot. Hemin pre-treatment reduced Dex-induced GR activity in PC3 cells. Protein levels of FKBP51, a cytoplasmic GR-binding immunophilin, were significantly increased in Hemin+Dex treated cells, possibly accounting for lower GR activity. We also evaluated these treatments in vivo using PC3 tumors growing as xenografts. We found non-significant differences in tumor growth among treatments. Immunohistochemistry analyses revealed strong nuclear GR staining in almost all groups. We did not observe HO-1 staining in tumor cells, but high HO-1 reactivity was detected in tumor infiltrating macrophages. Our results suggest an association and crossed modulation between HO-1 and GR pathways.

A hemin/graphene composite, prepared by mixing an aqueous solution of graphene oxide (GO) with hemin and sonicating the suspension for 5 h at room temperature, was investigated for olefination of aldehydes using ethyl diazoacetate in the presence of triphenylphosphine. Efficient olefination of aromatic aldehydes with high (E)-selectivity was obtained, revealing that rGO/hemin is a promising heterogeneous catalyst for the olefination reaction. The as-synthesized catalyst could easily be recovered from the reaction mixture and was subsequently used for several runs without any significantly loss in activity and selectivity.

Three new labdane diterpenes, curcucomosins A-C (1-3), four known labdane diterpenes, 4-7, and a known diarylheptanoid, 8, were isolated from the aerial parts of Curcuma comosa. The structures of the new diterpenes were elucidated by spectroscopic data analysis. The fetal hemoglobin (Hb F) induction potency of the isolated compounds was examined using a K562 reporter cell line harboring the enhanced green fluorescence protein (EGFP) gene under the control of a Ggamma-globin promoter. Compound 6, isocoronarin D, exhibited the highest Hb F induction effect of 1.6-fold at 20 muM.

Ferritin is a giant protein composed of 24 subunits which is able to sequester up to 4500 atoms of iron. We proposed two kinds of heme binding sites in mammalian ferritins and provided direct evidence for peroxidase activity of heme-ferritin, since there is the possibility that “ferritin-heme” systems display unexpected catalytic behavior like heme-containing enzymes. In the current study, peroxidase activity of heme-bound ferritin was studied using TMB1, l-DOPA, serotonin, and dopamine, in the presence of H2O2, as oxidant substrate. The catalytic oxidation of TMB was consistent with first-order kinetics with respect to ferritin concentration. Perturbation of the binding affinity and catalytic behavior of heme-bound His-modified ferritin were also documented. We also discuss the importance of the peroxidase-/nitrative-mediated oxidation of vital molecules as well as ferritin-induced catalase inhibition using in vitro experimental system. Uncontrollable “heme-ferritin”-based enzyme activity as well as up-regulation of heme and ferritin may inspire that some oxidative stress-mediated cytotoxic effects in AD-affected cells could be correlated to ferritin-heme interaction and/or ferritin-induced catalase inhibition and describe its contribution as an important causative pathogenesis mechanism in some neurodegenerative disorders.

The reaction between hydrogen peroxide and catechol catalyzed by mimetic peroxidase hemin has been adapted to determination of trace amounts of H 2O2. The present work employs hemin as mimetic peroxidase to catalyze the oxidation of catechol by H2O2. Its intermediate is obtained in aqueous-organic two phases and the absorption peaks at 260 nm. The catalytic optimum conditions for hemin-H2O 2-catechol two phases system were studied. As low as 2 × 10-6 M H2O2 could be detected with a linear range from 3 × 10-6 M to 1 × 10-4 M via spectrophotometry.

Herein, to mimic complex natural system, polyelectrolyte multilayer (PEM)-coated mesoporous silica nanoreactors were used to compartmentalize two different artificial enzymes. PEMs coated on the surface of mesoporous silica could serve as a permeable membrane to control the flow of molecules. When assembling hemin on the surface of mesoporous silica, the hemin-based mesoporous silica system possessed remarkable peroxidase-like activity, especially at physiological pH, and could be recycled more easily than traditional graphene-hemin nanocompounds. The hope is that these new findings may pave the way for exploring novel nanoreactors to achieve compartmentalization of nanozymes and applying artificial cascade catalytic systems to mimic cell organelles or important biochemical transformations Dividing lines: Polyelectrolyte multilayer (PEM)-coated mesoporous silica nanoreactors were constructed to compartmentalize two different artificial enzymes to mimic a complex natural system (see figure).
