In order to understand precise biological roles of sulfur dioxide (SO2), reliable SO2 donors, compounds that produce SO2 under physiological conditions, are necessary. The design and development of 1-phenyl-benzosultine as an efficient SO2 donor is reported. This compound undergoes cycloreversion to generate SO2 upon dissolution in aqueous buffer at 37 degrees C with a yield of 89% and a half-life of 39 min and shows SO2-like biological activity in a DNA cleavage assay.

Sulfurdioxide (SO2) is a gaseous environmental pollutant which is routinely used in industry as a preservative and antimicrobial. Recent data suggests that SO2 may have value as a therapeutic agent. However, due to its gaseous nature, localizing SO2 generation is challenging. Herein, various 1,3-dihydrobenzo[c]thiophene 2,2-dioxides (benzosulfones) were prepared as candidates for photochemically activated
二氧化硫(SO 2)是一种气态环境污染物,在工业上通常用作防腐剂和抗菌剂。最新数据表明,SO 2可能具有治疗作用。然而,由于其气态性质,本地化SO 2的产生是具有挑战性的。在此,制备各种1,3-二氢苯并[ c ]噻吩2,2-二氧化物(苯并砜)作为光化学活化的二氧化硫(SO 2)产生的候选物。发现这些化合物在缓冲液中稳定,但在紫外线照射下会被光解产生SO 2。。我们的数据表明苯砜的光解取决于取代基,并且给电子基团的存在导致SO 2的产率提高。
