Porphyrins and Metalloporphyrins
This is another of an increasing number of human gross anatomy books being published in abbreviated form. Throughout the book each left-hand page contains quite accurate written descriptions of structures that are illustrated as line drawings on the opposite right-hand page. Even though the text is written in a telegraphic style and the drawings are small, the book still contains 443 pages. It ...
متن کاملThe materials chemistry of porphyrins and metalloporphyrins
Porphyrins and metalloporphyrins provide an extremely versatile nanometer-sized building block for the control of materials properties. Films, solids and microporous solids have been explored as field-responsive materials (i.e. interactions with applied electric, magnetic or electromagnetic fields) and as ‘chemo-responsive’ materials (i.e. interactions with other chemical species as sensors or ...
متن کاملPorphyrins and Metalloporphyrins: Potential Hypoxic Agents
Synthetic water-soluble porphyrins and their metalloporphyrin derivatives with Co(III), Cu(II), Ru(II) and Pt(II), containing various functional groups within the meso-positions of the porphyrin, were synthesised and evaluated as hypoxic agents, especially as cytotoxins and radiosensitisers. Cobalt complexes of the porphyrins containing positively charged methylpyridinium groups showed selectiv...
متن کاملThe Interaction of Porphyrins and Metalloporphyrins with Apocytochrome b5*
The preparation of undenatured apocytochrome bs and the apoprotein of an iodinated and acetylated derivative of cytochrome bs made possible the examination of the characteristics of hemei binding in this heme protein (2). A specific imidazole group on the apocytochrome was implicated in this reaction by stoichiometric titration of this single group on the iodinated and acetylated apoprotein wit...
متن کاملEffects of polyhalogenated aromatic compounds on porphyrin metabolism.
Heme production is a vital metabolic process that occurs in the bone marrow and liver. Porphyrins are unused by-products of this biosynthetic process and normally occur in urine and other body fluids in low concentrations. Various disorders can disrupt the heme biosynthetic process, causing greater quantities of porphyrins in urine. The porphyrias are a group of diseases characterized by excess...
