Methyl sulfone

Methyl sulfone (CAS No.: 67-71-0) is a small organic sulfur compound belonging to the sulfone class and is widely recognized as a naturally occurring oxidized metabolite derived from endogenous methanethiol metabolism and intestinal microbial activity, as well as from the oxidation of dimethyl sulfoxide. In biomedical research, it is primarily categorized as a bioactive metabolite and analytical reference standard with reported anti-inflammatory, antioxidant, and analgesic properties, and has been investigated for its potential neuroprotective effects. Mechanistically, methyl sulfone has been shown to inhibit choriocapillary endothelial cell proliferation and is thought to modulate oxidative stress responses and inflammatory signaling pathways, although its precise molecular targets remain incompletely defined. In vitro studies generally report biological activity in the micromolar range, consistent with modest potency typical of small endogenous metabolites. It is frequently utilized in cell-based assays to examine endothelial function, inflammatory responses, and oxidative stress modulation, and is also employed in pharmacological and forensic contexts as a reference compound or adulterant marker. Experimental applications in both in vitro and in vivo systems typically involve concentration ranges and dosing regimens that are adjusted according to specific study designs, particularly in investigations related to inflammation, neuroprotection, and metabolic biochemistry.
