Supramolecular nanoarchitectonics with TPPS porphyrin as a …
Tetraphenylporphyrin, abbreviated TPP or H2TPP, is a synthetic heterocyclic compound that resembles naturally occurring porphyrins. Porphyrins are dyes and cofactors found in hemoglobin and cytochromes and are related to chlorophyll and vitamin B12. The study of naturally occurring porphyrins is complicated by their low symmetry and the presence of polar substituents. Tet… SpletA ferric porphyrin complex that catalytically isomerizes peroxynitrite to nitrate both in vivo and in vitro.

SpletA porphyrin is a heterocyclic macrocycle derived from four pyrroline subunits interconnected via their α carbon atoms via methine bridges (=CH-). The macrocycle, therefore, is a highly-conjugated system, and, as a consequence, is deeply coloured - the name porphyrin comes from a Greek word for purple.The macrocycle has 22 pi … SpletThus we decided to investigate structure-activity relationships of a serie of anionic porphyrins toward Tobacco Bright Yellow - 2 (TBY-2) cells, namely 5,10,15,20-tetrakis(carboxyphenyl) porphyrin TPPC, its zinc analogue Zn-TPPC, 5,10,15,20-tetrakis(4-sulfonatophenyl) porphyrin TPPS, and its zinc analogue Zn-TPPS, 5,10,15,20-tetrakis(4 ... SpletThe present invention provides photosensitizing agents obtained by reducing a single double bond in the porphyrin macrocycle of a sulphonated meso-tetraphenylporphyrin, preferably a disulphonated meso-tetraphenylporphyrin such as TPPS¿2a?. The resulting sulphonated meso-tetraphenyl chlorins include compounds of formula (I) (wherein X is … hair salons in elkhorn wi
