Use ofDimethyl sulfoxide (DMSO) is an aprotic solvent that dissolves both polar and nonpolar compounds. Dimethyl sulfoxide has anti-freezing and bacteriostatic properties[1][2]. Properties Articles7647 Name dimethyl sulfoxide Synonym More Synonyms Dimethyl sulfoxide Biological Activity Description Dimethyl sulfoxide (DMSO) is an aprotic solvent that dissolves both polar and nonpolar compounds. Dimethyl sulfoxide has anti-freezing and bacteriostatic properties[1][2]. Related Catalog Research Areas >> Infection Research Areas >> Inflammation/Immunology Signaling Pathways >> Anti-infection >> Bacterial In Vitro DMSO is an organic solvent that is freely miscible with water, lipids and organic agents. These properties allow for exceptional membrane penetration. The mechanism of action of DMSO is thought to be a combination of anti-inflammatory effects, nerve blockade, smooth muscle relaxation, and collagen inhibition[2]. References [1]. C F Brayton.
