  • Ligands
  • 4-6 The reports of atom transfer reactions by pentagonal bipyramidal (PBP) Fe-oxido and amido complexes based on the qpy (2,2′:6′,2′′:6′′,2′′′:6′′′,2′′′′-quinquepyridine) and tris(2-picolyl)amine ligands complement the well-established atom transfer chemistry of lower-coordinate iron compounds. (rsc.org)
  • It consists of three p-vinylphenyl-3-nitroso-4-hydroxybenzoate ligands complexed with a ferrous ion. (wikipedia.org)
  • Ferroverdin is immune to chelating and oxidizing agents due to the strong interaction between the ligands and ferrous ion. (wikipedia.org)
  • salts
  • While their mechanism of antimalarialaction is still studied and debated,5−16 the prevailing view is that Fenton-type reduction by ferrous ironsources within the parasite is an essential, activating chemical event.Various in vitro studies7,11,13,17 have confirmed the intermediacyof carbon-centered radicals following exposure of arterolane-likemodel systems to inorganic iron(II) salts or iron(II) heme. (nih.gov)
  • The presence of reddish or orange mottles indicates localised re-oxidation of ferrous salts in the soil matrix, and is often associated with root channels, animal burrows or cracking of the soil material during dry spells. (wikipedia.org)
  • myoglobin
  • One of the first functional analogues of myoglobin was the ferrous derivative of the "picket fence porphyrin," which is structurally related to Fe(TPP), being derived via the condensation of 2-nitrobenzaldehyde and pyrrole. (wikipedia.org)
  • synthesis
  • Efficient and stereocontrolled synthesis of 1,2,4-trioxolanes useful for ferrous iron-dependent drug delivery. (nih.gov)
  • A stereocontrolled, expeditious (three steps), and efficient (67-71% overall yield) synthesis of 1,2,4-trioxolanes possessing the requisite 3″ substitution pattern that enables ferrous iron-dependent drug delivery is reported. (nih.gov)
  • refers
  • Ferroverdin refers to three different coordination compounds that were first isolated in 1955 by Chain, Tonolo, and Carilli. (wikipedia.org)
  • CAS numbers form an extreme example of names that do not perform this function: each CAS number refers to a single compound but none contain information about the structure. (wikipedia.org)
  • reduction
  • Ferrous iron-promoted reduction of a hindered peroxide bond underlies the antimalarial action of the 1,2,4-trioxane artemisinin and the 1,2,4-trioxolane arterolane. (nih.gov)
  • naturally
  • Tetraphenylporphyrin, abbreviated TPP or H2TPP, is a synthetic heterocyclic compound that resembles naturally occurring porphyrins. (wikipedia.org)
  • reveal
  • Standard free energies for the binding of NO and CO reveal high selectivity of the ferrous cyt c'' for NO, indicating its putative physiological role. (bireme.br)
  • high
  • The use of this compound compared with other iron preparations results in satisfactory reticulocyte responses, a high percentage utilization of iron, and daily increase in hemoglobin that a normal level occurs in a reasonably short time. (wikipedia.org)
  • provide
  • Certain compounds of chromium are used to provide chrome yellows, oranges, and greens, while various compounds of cadmium yield brilliant yellows, oranges, and reds. (britannica.com)
  • The superoxide dismutase activities of the pentagonal bipyramidal Fe(dapsox) and pentaaza macrocyclic iron compounds provide noteworthy examples of biological relevance. (rsc.org)
  • Approaches to track the activity of such cells in vivo with MRI have employed labeling with ferrous compounds to provide MR contrast effects. (ahajournals.org)
  • materials
  • Reactions within a cell change the incoming materials into new compounds, some of which are redistributed within the cell substance, others including the waste products leave the cell. (tolueislam.org)
  • water
  • We observed that 62,000 cells can be imaged 24 hours following intramuscular injection in vivo at 11.7 T. Accordingly, PFC NP show promise as an alternative to ferrous contrast agents for cell tracking in vivo as a nontoxic, unique, and quantifiable signal that can be imaged without obscuring background water signal. (ahajournals.org)
  • sometimes
  • Unlike natural porphyrins, H2TPP is substituted at the oxidatively sensitive "meso" carbon positions, and hence the compound is sometimes called meso-tetraphenylporphyrin. (wikipedia.org)
  • Name
  • In a few specific circumstances (such as the construction of large indices), it becomes necessary to ensure that each compound has a unique name: This requires the addition of extra rules to the standard IUPAC system (the CAS system is the most commonly used in this context), at the expense of having names that are longer and less familiar to most readers.
