Thiol-activated hydrogen sulfide donor 8l and 8о prepared from penicillamine release H2S upon reaction with reducing agents containing sulfhydryl groups such as cysteine and reduced glutathione in a similar manner to 5a. The H2S releasing rates depend on concentrations of thiols, and donor 8о gives a slower H2S releasing rate than donor 8l. These donors are useful to investigate the effects of H2S releasing rates on cellular functions. *H2S donor 8l and 8o were developed by Dr. Ming Xian of Washington State University.
