Alexander disease mutations differentially sensitize glial fibrillary acidic protein (GFAP) to posttranslational modifications and network disruption by oxidants [PDF]
Redox BiologyThe type III intermediate filament protein glial fibrillary acidic protein (GFAP) plays a key role in astrocyte and brain homeostasis. Mutations in GFAP can result in Alexander's disease (AxD), a severe neurodegenerative disease.

The hydrogen atom transfer reactivity of sulfinic acids. [PDF]
Chem Sci, 2018 Sulfinic acids are characterized to be very good H-atom donors to each of alkyl and alkoxyl radicals. In order to participate in useful radical chain reactions, the sulfonyl radicals must undergo fast propagating reactions to avoid autoxidation, which is surprisingly rate-limited by the reaction of sulfonyl radicals with oxygen.

Electrochemical oxidation of clonazepam drug in the presence of arylsulfinic acid in aqueous solutions: A green method for synthesis new sulfonamide derivatives [PDF]
شیمی کاربردی روز, 2023 The electrochemical oxidation of clonazepam (CLNP) has been studied in presence of some aryl sulfinic acids as nucleophiles in aqueous buffered solution by means of cyclic voltammetry, and controlled- potential coulometry.

Secondary aerosol formation from dimethyl sulfide – improved mechanistic understanding based on smog chamber experiments and modelling [PDF]
Atmospheric Chemistry and Physics, 2021 Dimethyl sulfide (DMS) is the dominant biogenic sulfur compound in the ambient marine atmosphere. Low-volatility acids from DMS oxidation promote the formation and growth of sulfur aerosols and ultimately alter cloud properties and Earth's climate.

Novel one-step preparation of sulfinic acid derivatives from sulfinic acid.
Chemical and Pharmaceutical Bulletin, 1980 Convenient one-step syntheses of sulfinamides and sulfinate esters from sulfinic acids were achieved by using coupling reagents, such as 2-chloro-1-methylpyridinium iodide, γ-saccharine chloride, N, N'-dicyclohexylcarbodiimide, and diethyl azodicarboxylate and triphenylphosphine. Ammonolysis of sulfinate esters also gave sulfinamides.
