1,5-Dithiacyclooctane is shown to chemically react more efficiently and to remove singletoxygen from solution more rapidly than either thiane or 1,4-dithiane. These unusual characteristics of the 1,5-dithiacyclooctane reaction were explored using ab initio quantum chemical methods. A large number of persulfoxides, thiadioxiranes, and hydroperoxy sulfonium ylides were located and their structures analyzed
efficiently than the popular asparagusic acid. Added as competitive agents, CTOs inhibit the uptake of various COC transporters and SARS-CoV-2 lentivectors. Orthogonal trends found with different transporters support the existence of multiple cellular partners to account for the diverse expressions of thiol-mediateduptake. Dominant self-inhibition and high activity of dimers imply selective and synergistic

Exchange dynamics: Reported are structure-property-function relationships of cyclic thiosulfonate molecules—disulfide-bond disrupting agents (DDAs)—that downregulate the Epidermal Growth Factor Receptor (HER) family in parallel and selectively induce apoptosis of EGFR+ or HER2+ breast cancer cells. Shown recently, the DDAs covalently bind to the active site cysteine residue(s) of selected protein disulfide
