Antioxidant activity of 5,10-dihydroindeno[1,2-b]indoles containing substituents on dihydroindeno part

Apoptotic, antioxidant and antiradical effects of majdine and isomajdine from Vinca herbacea Waldst. and kit

“…Generation of the ABTS radical cation forms the basis of one of the spectrophotometric methods that have been applied to the measurement of the total antioxidant activity of pure substances, aqueous mixtures and beverages 20 . A more appropriate format for the assay is a decolourisation technique in which the radical is generated directly in a stable form prior to the reaction with putative antioxidants.…”

“…The reaction of the pre-formed radical with free radical scavengers can be easily monitored by following the decay of the sample absorbance at 734 nm 20 . The principle of the DMpD •+ assay is that DMpD can form a stable and coloured radical cation (DMpD •+ ) at acidic pH and in the presence of a suitable oxidant solution.…”

Acethylcholinesterase inhibitory potential and antioxidant properties of pyrogallol

“…Total volume was adjusted to 2 mL and kept at room temperature during 30 min. Absorbance was measured at 450 nm in spectrophotometer 12 .…”

Synthesis of some tetrahydropyrimidine-5-carboxylates, determination of their metal chelating effects and inhibition profiles against acetylcholinesterase, butyrylcholinesterase and carbonic anhydrase

“…-binding capacity of tetrahydropyrimidine-5-carboxylates (1-3) was spectrophotometrically recorded at 522 nm 93 . In brief, to a mixture of FeCl 2 (0.1 mL, 0.6 mM), tetrahydropyrimidine-5-carboxylates (1-3) were added at three different concentrations (10-30 mg/mL) in methanol (0.4 mL).…”
