Synthesis of new indole-2-carboxamide and 3-acetamide derivatives and evaluation their antioxidant properties
摘要:
In recent years, antioxidant compounds play an important role as a health-protecting factor. Antioxidants protect cells against the damaging effects of reactive oxygen species (ROS). An imbalance between antioxidants and ROS results in oxidative stress, which leads to cellular damage and it is linked to many vital diseases. It was shown that heme oxygenase (HO) provides efficient cytoprotection against oxidative stress. In this study, a series of indole-2-carboxamide and 3-acetamide derivatives was tested for in vitro effects on HO activity and 2,2-diphenyl-1-picrylhydrazyl (DPPH) inhibition. Among the synthesized compounds, N-[3-(dimethylamino)propyl]-1H-indole-2-carboxamide 3 was found as the most activator of HO and N-(2-(dimethylamino)ethyl)-2-(1H-indol-3-yl)acetamide 8 was found the most potent inhibitor for DPPH at 10(-4) M concentration.

A series of heterocyclic N-[(diethylamino)alkyl]arenamides related to acecainide was prepared and examined for antiarrhythmic activity. The compounds were synthesized from the corresponding known heterocyclic carboxylic acids or esters by using standard amide formation methods. The effects of the compounds on the electrophysiological properties of canine Purkinje fibers and ventricular muscle strips
