Molecular Complex of a Cationic Porphyrin andp-Nitrophenol. Verification of the Porphyrin Dimerization

Synthesis of cationic porphyrin modified amino acids.

Derivatives of amino acids bearing a porphyrin moiety on a side chain were synthesized by coupling a porphyrin to a glutamic acid side chain; the utility of these compounds was demonstrated by their use in solid-phase synthesis of a peptide bearing a cationic porphyrin and by studying its DNA-binding properties.

DNA groove binding of an asymmetric cationic porphyrin and its Cu(II) complex: Resolved by spectroscopic, viscometric and molecular docking studies

In the present study, the interaction between water-soluble cationic asymmetric porphyrin, 5-(1-Hexadecyl pyridinium-4-yl)-10, 15, 20-tris (1-Butyl pyridinium-4-yl) Porphyrin Chloride, and its copper (II) derivative with calf thymus DNA (CT-DNA) were studied by means of spectroscopic techniques, viscosity measurements and molecular docking. The monitoring of the changes in visible absorbance sp...

Structure of DNA-porphyrin complex.

We report the 2.4 A resolution X-ray structure of a complex in which a small molecule flips a base out of a DNA helical stack. The small molecule is a metalloporphyrin, CuTMPyP4 [copper(II) meso-tetra(N-methyl-4-pyridyl)porphyrin], and the DNA is a hexamer duplex, [d(CGATCG)]2. The porphyrin system, with the copper atom near the helical axis, is located within the helical stack. The porphyrin b...

Molecular porphyrin – fullerene architectures *

This article describes the utilization of porphyrin and fullerene architectures— yielding artificial light-harvesting antenna and reaction center mimics—to tune the electronic coupling element between electron donor and electron acceptor and ultimately to affect the total reorganization energy. Most importantly, the effects that these parameters have on the rate, yield, and lifetime of the ener...
