Fig. 3From: Synthesis, in vitro biological evaluation and molecular modelling of new 2-chloro-3-hydrazinopyrazine derivatives as potent acetylcholinesterase inhibitors on PC12 cellsAntioxidant activities of synthesized compounds. Scavenging activity of prepared compounds on A ABTS radicals and B DPPH radicals (Ascorbic acid is used as a standard), and C concentration values of Fe2+ which indicate significant antioxidant properties in all of the synthesized compoundsBack to article page
