Although sulfur dioxide (SO2) finds widespread use in the food industry as its hydrated sulfite form, a number of aspects of SO2 biology remain to be completely understood. Of the tools available for intracellular enhancement of SO2 levels, most suffer from poor cell permeability and a lack of control over SO2 release. We report 1,2-cyclic sulfite diesters as a new class of reliable SO2 donors that dissociate in buffer through nucleophilic displacement to produce SO2 with tunable release profiles. We provide data in support of the suitability of these SO2 donors to enhance intracellular SO2 levels more efficiently than sodium bisulfite, the most commonly used SO2 donor for cellular studies.
Photoreactions of cyclic sulfite esters: Evidence for diradical intermediates
White, Rick C.,Arney Jr., Benny E.,Ihmels, Heiko
experimental part, p. 1208 - 1212 (2012/09/22)
The photochemistry of a phenyl and 1, 2-diphenyl substituted sulfite ester is reported. The performance of photoreactions under relatively mild reaction conditions enables the detection of products that have not been observed in previous studies. It is concluded that, complementary to the initially proposed carbene intermediates, diradicals may also be considered.
