Photoreactivation1, 2 is the reversal of the harmful effects, such as growth delay,
mutagenesis, and killing, of far UV (200-300 nm) on organisms by concurrent or subsequent …

The photochemical reaction between an excited state of carbonyl compounds and an alkene
to give the oxetane deriving from a cycloaddition reaction (the Paternò–Büchi reaction) is …

The second edition of this best-selling handbook is bigger, more comprehensive, and now
completely current. In addition to thorough updates to the discussions featured in the first …

Structural analysis, biochemistry and model studies have provided new insights into the
mechanism of action of photolyases. The light-driven electron and energy transfer events …

The (6-4) photolyase catalyzes the photoreversal of the (6-4) dipyrimidine photoproducts
induced in DNA by ultraviolet light. Using the cloned Drosophila melanogaster (6-4) …

Guanine is the most easily oxidizable base in DNA under various oxidative conditions (see
section 4), including in the presence of the hydroxyl radical (OH•) and related radicals …

Triplet-mediated pyrimidine (Pyr) dimerisation is a key process in photochemical damage to
DNA. It may occur in the presence of a photosensitiser, provided that a number of …

In a process called photoreactivation, blue light reverses the chemical damage done to DNA
by ultraviolet light. One mediator of this effect is the enzyme CPD photolyase; a second …

The Paternò-Büchi reaction is a photochemical reaction between a carbonyl compound and
an alkene to give the corresponding oxetane. In this review the mechanism of the reaction is …

Novel electron-transfer-induced intermolecular [2+ 2] cycloaddition reactions between an
aliphatic cyclic enol ether and several unactivated olefins have been demonstrated on the …
