Trimethylsulphoxonium chloride

Trimethylsulfoxonium chloride is a quaternary ammonium salt that is used as a phospholipid membrane disruptor. It has been studied for its clinical profile and antiviral activity in vitro. Trimethylsulfoxonium chloride also has anti-fungal and anticancer properties, which are due to its ability to inhibit the synthesis of lipid-containing macromolecules. This drug may be useful as a growth regulator in plants. Trimethylsulfoxonium chloride is prepared by an asymmetric synthesis using acetone and ethyl chloroacetate. The reaction mechanism is not well understood but it may involve the addition of the thiol group to the sulfur atom of the sulfoxide ion, followed by hydrolysis of the phosphate ester and elimination of water.
