A survey of acid catalysts in dipyrromethanecarbinol condensations leading to meso-substituted porphyrins
10.1002/jpp.387 2001-12-31 The successful use of dipyrromethanecarbinols in rational routes to porphyrinic macrocycles requires catalysis conditions that enable irreversible condensation, thereby avoiding substituent scrambling and formation of undesired porphyrin products. Previously,... |

Evaluation studies of technetium-99m-porphyrin (T3,4BCPP) for tumor imaging
10.1002/jpp.546 2001-12-31 A water-soluble porphyrin, 5,10,15,20-tetrakis[3,4-bis(carboxymethyleneoxy)phenyl] porphyrin (T3,4BCPP), was successfully labeled with 99mTc and biodistribution studies were performed in Wistar rats. Scintiimaging and in vivo distribution studies were also ca... |

Kinetics of zinc ion incorporation in base into a centrally aprotic beta-octabrominated cationic water-soluble porphyrin and its monolithium complex
10.1002/jpp.549 2001-12-31 The kinetics of zinc incorporation from pH 12 to 13 into the centrally aprotic BrP(4)2+ form of beta-octabromo-meso-tetrakis(N-methyl-4-pyridyl)porphyrin and its monolithium complex were studied at 25.0 °C, ionic strength (I) = 0.10. The reactions were first ... |

Synthesis of N-phytochlorin-substituted [60]fulleropyrrolidines
10.1002/jpp.550 2001-12-31 A series of new phytochlorin–fullerene dyads was prepared. Synthetic pathway includes attachment of glycine to aldehyde-containing phytochlorins via reductive amination, where 3- and 7-carbonyl-substituted pheophorbides exhibit surprisingly different reactivi... |

Spectroscopic studies of the interaction of cobalt(II) N,N′,N″,N″′-tetramethyltetra-3,4-pyridinoporphyrazine with amino acids and nitrogen oxides
10.1002/jpp.551 2001-12-31 The interaction of histidine, cysteine, NO and nitrite with cobalt(II) N,N′,N″,N″′-tetramethyltetra-3,4-tetrapyridinoporphyrazine ([CoIItmtppa]4+) is reported. Metal-based autoreduction of [CoIItmtppa]4+ occurs with the formation of the [CoItmtppa(−2)]3+ spec... |

A non-tetradecarboxylative synthesis of 2,7,12,17-tetraphenylporphycene
10.1002/jpp.552 2001-12-31 A new synthetic method for 2,7,12,17-tetraphenylporphycene (2e, TPPo) which avoids tetradecarboxylation by sublimation of the intermediate tetracarboxylic acid 8 is reported. Thus, the use of a pyrrol 13a bearing two orthogonal ester groups allows the synthes... |

PDT-related photophysical properties of conformationally distorted palladium(II) porphyrins
10.1002/jpp.553 2001-12-31 The photodynamic therapy (PDT) related photophysical properties of five palladium(II) porphyrins with increasing steric demand of the meso-substituents were investigated by steady state and time-resolved absorption and luminescence spectroscopy. The steric st... |

5,15-Diaryl-β-substituted-porphyrinato-manganese(III) chlorides as probes for structure–activity relationships in porphyrin-based epoxidation catalysts
10.1002/jpp.554 2001-12-31 Manganese complexes of 5,15-diaryl-β-substituted-porphyrins were prepared and their behaviour as oxidation catalysts was studied. The role of the pyrrolic and meso-substituents on the activity and selectivity of these catalysts was studied to reveal new struc... |
