Porphyrin and phthalocyanine antiscrapie compounds.
The transmissible spongiform encephalopathies (TSEs) are fatal, neurodegenerative diseases for which no effective treatments are available. The likelihood that a bovine form of TSE has crossed species barriers and infected humans underscores the urgent need to identify anti-TSE drugs. Certain cyclic tetrapyrroles (porphyrins and phthalocyanines) have recently been shown to inhibit the in vitro ...
متن کاملCage Compounds and Redox Synthesis
Intermetallic clathrates were discovered in the 1950s when the basic relations of alkali metals and group 14 elements were investigated [1, 2]. After the structural elucidation of Na8Si46 and NaxSi136 [3] the research field spread continuously, and representatives comprising Na, K, Rb and Cs were obtained. The only exception was the Li-containing clathrate and it was concluded that Li atoms are...
متن کاملPorphyrin Compounds Derived from Bacteria
The pigment contained in the extracts obtained from B. phosphorescens by freezing and thawing, and in the alkaline extracts of B. phosphorescens and yeast, resembles the "cytochrome c" of Hill and Keilin (6) and the "porphyratin B" of Schumm (7) in giving absorption bands at mmicro 552-550 and 522-520) but shows in addition a band about 575, as in the "hemochromogen A" obtained by Keilin (3) by...
متن کاملSynthesis of novel acetal thia-cage compounds.
The synthesis of novel acetal thia-cage compounds has been accomplished by the direct substitution for the oxygen atom by the sulfur atom in the reaction of the acetal groups of oxa-cages with Lawesson reagent (LR). Reaction of the tetraoxa-cage compound 2 with LR in dichloromethane at 25 degrees C sequentially gave the monothia-, dithia-, trithia-, and tetrathia-cage compounds 3, 6, 7, and 9. ...
متن کاملErythrocyte Acetylcholinesterase-Inhibitory Activity of Porphyrin Compounds
Acetylcholinesterase (AChE) inhibition is important because of its health-related implications. Three porphyrin derivatives, Tetraphenylporphinesulfonate (TPPS), 5, 10, 15, 20-Tetrakis (4sulfonatophenyl) porphyrinato Iron (III) Chloride (FeTPPS) and 5, 10, 15, 20-Tetrakis (4-sulfonatophenyl) porphyrinato Iron (III) nitrosyl Chloride (FeNOTPPS), were tested by Molecular Docking as inhibitors of ...
