Chemical conjugates of H 2S-donors and non-steroidal anti-inflammatory drugs (NSAIDs) are being investigated as anti-inflammatory and chemoprevention agents [ 1]. Dithiolethiones, in particular 5-(4-methoxyphenyl)-3 H-1,2-dithiole-3-thione ( 1a, ADT), are H 2S donors and exhibit marked antioxidant activity (free-radical binding, lipid peroxidation inhibition) [ 2]. Desmethylanethol trithione ( 1b, ADTOH) is a known ADT metabolite and is used as a synthon to prepare new promising NSAID conjugate derivatives [ 3]. Available triterpenoids such as ursolic acid (UA, 2a) and its synthetic derivatives were also reported to have anti-inflammatory, antioxidant, and antitumor activity [ 4].
