Thiol drugs examples
WebFor example, the fluorescence of a fluorophore conjugated to a drug through an S S bond is quenched via a photoinduced electron transfer mechanism. Reacting with glutathione (GSH), the S S bond is cleaved and undergoes an intramolecular nucleophilic attack at the carbamate moiety to yield a five-membered ring, both releasing the drug and ... WebThiol groups are readily oxidized by the mammalian peroxidases, either directly through electron abstraction or indirectly through the action of their hypohalide products. For example, spin trapping and oxygen consumption experiments with LPO have shown that this enzyme can oxidize the thiol groups of cysteine, cysteamine, N-acetylcysteine, …

WebCdTe QDs has been demonstrated in many studies to possess good outstanding optical and photo-physical properties. However, it has been established from literature that the toxic Cd2+ that tends to leak out into nearby solutions can be protected by less toxic ZnS or ZnSe shells leading to the synthesis of core-shells and multi-core-shells. Hence, this has …
