Metalloporphyrins – An Update
Metalloporphyrins are structural analogs of heme and their potential use in the management of neonatal hyperbilirubinemia has been the subject of considerable research for more than three decades. The pharmacological basis for using this class of compounds to control bilirubin levels is the targeted blockade of bilirubin production through the competitive inhibition of heme oxygenase (HO), the ...
متن کاملPorphyrins 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 کاملDendrimer-Metalloporphyrins: Synthesis and Catalysis
A new class of sterically hindered dendrimer-metalloporphyrins was synthesized for use as shape-selective oxidation catalysts. A series of oxidatively robust poly(phenylesters) dendrimers were prepared through a convergent synthesis. Monodendrons were appended to the meta-positions of the 5,10,15,20-tetrakis(3′,5′-hydroxyphenyl)porphinatomanganese(III) chloride to obtain a sterically protected ...
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 کاملNovel Metalloporphyrins as Molecular MR Contrast Agents
Introduction: To date, no imaging methodology exists which can image prostate cancer in vivo with sufficient sensitivity and specificity for diagnostic utility. As a consequence, urological surgeons and oncologists proceed with treatment strategies based on ‘blind’ biopsy tissue specimens and limited diagnostic evaluations using conventional MRI and ultrasound. In these experiments, we have inv...
