It has been related to neurological diseases (Parkinson or Alzheimer’s) because of unfolded protein response phenomena. WebDisulfide bonds are covalent bonds formed by the oxidation of cysteine side-chains and are present in at least 20% of proteins, but their function is not fully understood. In our study, …
WebMay 4, 2024 · Disulfide bonds have been widely used to develop reduction-responsive drug-delivery systems (DDS) for cancer therapy. We propose that disulfide bonds might be also used as an oxidation-responsive linkage just like thioether bonds, which can be oxidized to hydrophilic sulfoxide or sulphone in the presence of oxidation stimuli. To test our … WebMay 20, 2024 · Disulfide oxidation can therefore give rise to long-lived oxidants on proteins that can undergo further reaction with thiols, including GSH and other proteins, to give …
