New Derivatives of 3,4-Dihydroisoquinoline-3-carboxylic Acid with Free-Radical Scavenging, d-Amino Acid Oxidase, Acetylcholinesterase and Butyrylcholinesterase Inhibitory Activity
A series of 3,4-dihydroisoquinoline-3-carboxylic acid derivatives were synthesised and tested for their free-radical scavenging activity using 2,2-diphenyl-1-picrylhydrazyl radical (DPPH(·)), 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) radical (ABTS(·+)), superoxide anion radical (O(...

Sumario: | A series of 3,4-dihydroisoquinoline-3-carboxylic acid derivatives were synthesised and tested for their free-radical scavenging activity using 2,2-diphenyl-1-picrylhydrazyl radical (DPPH(·)), 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) radical (ABTS(·+)), superoxide anion radical (O(2)(·−)) and nitric oxide radical ((·)NO) assays. We also studied d-amino acid oxidase (DAAO), acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE) inhibitory activity. Almost each of newly synthesised compounds exhibited radical scavenging capabilities. Moreover, several compounds showed moderate inhibitory activities against DAAO, AChE and BuChE. Compounds with significant free-radical scavenging activity may be potential candidates for therapeutics used in oxidative-stress-related diseases. |
