DNA intercalation and photosensitization by cationic meso substituted porphyrins.

Several cationic porphyrins are known to bind to DNA by intercalative and outside binding modes. This study identifies the cis and trans isomers of bis(N-methyl-4-phridiniumyl)diphenyl porphyrin as DNA intercalators based on evidence from a DNA topoisomerase I assay. Moreover, both isomers are shown to be potent photosensitizers of DNA, inducing multiple S1 nuclease sensitive breaks in the phos...

Optimal Sunlight Harvesting in Photovoltaics and Photosynthesis

Materials employed to harvest sunlight are commonly recognized to be at a premium when their optical absorption peaks in the visible, extends to the infrared, is panchromatic, and is matched to the solar spectrum. By contrast, natural photosynthetic absorbers such as chlorophylls and carotenoids display absorption spectra with narrow peaks for yet-unknown evolutionary reasons. Beyond such gener...

Fasting and apoptosis: a mini review

Fasting, that is usually described as abstinence from all food and drink for a period of time, has been experienced for ages. Health, protest, religious expressions of devotion and purification are the most important reasons for fasting. Many changes occur in the body during fasting including metabolic, mineral, hormonal, immunological and psychological. Its use as one of the oldest therapies a...

5,10-A2B2-type meso-substituted porphyrins--a unique class of porphyrins with a realigned dipole moment.

Current applications in porphyrin chemistry require the use of unsymmetrically substituted porphyrins. Many current industrial interests in optics and biomedicine require systems with either push-pull (electron-donating and -withdrawing groups) or amphiphilic systems (hydrophobic and hydrophilic groups). In this context we present the class of 5,10-A(2)B(2)-type porphyrins for which two differe...

Spectroscopic and computational study of β-ethynylphenylene substituted zinc and free-base porphyrins.

A series of tetraphenylporphyrins appended at the β-pyrrolic position with an ethynylphenylene- or ethynylpyridine-substituent have been subjected to spectroscopic and density functional theory (DFT) analyses. The mean absolute deviation between corresponding experimental and DFT-derived vibrational spectra is up to 10.2 cm(-1), suggesting that the DFT B3LYP/6-31G(d) method provides an accurate...
