Sulfane Sulfur Probe 4

一种用于检测硫烷硫物种（sulfane sulfur species）的荧光探针；在硫烷硫物种存在时，该探针可发生亲核反应，生成荧光素（激发/发射波长分别为494nm/515nm），同时生成两分子的1,2-苯并二硫杂卓-3-酮。该探针已被用于确定小鼠原代神经元中H2S3的定位，并检测日本豆苗根中的多硫化物。A fluorescent probe for sulfane sulfur species; subject to nucleophilic reaction in the presence of sulfane sulfur species resulting in the formation of fluorescein, which displays ex/em = 494/515 nm, respectively, and two molecules of 1,2-benzodithiol-3-one; has been used to determine localization of H2S3 in primary mouse neurons and to detect polysulfides in L. japonicus seedling roots.分子式C34H20O7S2分子量604.6O=C(O1)C2=C(C=CC=C2)C31C4=CC=C(OC(C5=C(S)C=CC=C5)=O)C=C4OC6=C3C=CC(OC(C7=CC=CC=C7S)=O)=C6
