Inhibition of methionine sulfoxide reduction by dimethyl sulfoxide
BMB Reports, 2009 Dimethyl sulfoxide (DMSO) is widely used in chemistry and biology as a solvent and as a cryoprotectant. It is also used as a pharmaceutical agent for the treatment of interstitial cystitis and rheumatoid arthritis. Previous reports described DMSO as being reduced by methionine-S-sulfoxide reductase (MsrA).

Highly Enantioselective Oxidations of Ketene Dithioacetals Leading to Trans Bis-sulfoxides
, 2016 Ketene dithioacetals undergo a Sharpless-type asymmetric oxidation using (+)-DET, Ti(OiPr)4, and cumene hydroperoxide to give the trans bis-sulfoxides 4a−f with essentially complete control of enantioselectivity and diastereoselectivity.
