Dithiocarbamates of various substituted tetrahydro-β-carbolines were synthesized and tested for hepatoprotective activity against carbon tetrachloride (CCl4) -induced liver damage in mice. Structure-activity relationships were investigated. Some neighboring group participation of the 3-substituent with the dithiocarbamate group appeared to be important for the manifestation of activity. The compounds (1a, 2a, and 3i) with hydrophilic substituents at the 3 poisition exhibited significant activity. Substitution at the 9 position of the 3-carboxylic acid (1a) lowered the activity.
合成了多种取代四氢-β-吲哚-二硫代氨基甲酸盐,并测试了其在小鼠中对四氯化碳 (CCl4) 诱导的肝损伤的肝保护活性。研究了结构-活性关系。3位取代基与二硫代氨基甲酸盐基团的相邻基团参与似乎对活性的体现非常重要。在3位具有亲水性取代基的化合物(1a、2a 和 3i)表现出了显著的活性。在3-羧酸(1a)的9位进行取代则降低了活性。
