Photochemical properties of gemifloxacin: A laser flash photolysis study

Photosensitive damage of dipeptides: mechanism and influence of structure

“…14 Due to their high reactivity, various reaction targets have been identified including free forms of tryptophan (Trp), tyrosine (Tyr), and methionine. 15–18…”

Investigation on the photoinduced chemical reaction between p-benzoquinone and tryptophan in homogeneous solution

“…Although endogenous photosensitizers are usually present at relatively low concentrations, their influence on the photochemical reaction of organisms cannot be ignored; actually a large number of reactions between endogenous photosensitizers and amino acids have been reported. 5,6…”

“…9,10 In 2015, the reaction between Trp and gemifloxacin was reported by Xu et al , who investigated the quenching of excited triplets of gemifloxacin by Trp, and the bimolecular quenching rate constant was determined to be 2.2 × 10 7 M −1 s −1 . 5 In 2020, Fracassetti et al reported the effect of gallic acid and sulfur dioxide on photoinduced oxidation of methionine, which revealed that gallic acid inhibited the increase of Met sulfoxide while sulfur dioxide promoted the production of Met sulfoxide. 6…”
