Investigation of the scavenging mechanism of tyrosyl radical by hydroxybenzohydroxamic acid derivatives: A DFT study.

Highlights: [•] Kinetic data indicate that trimidox is more active radical scavenger than other investigated compounds. [•] The most favorable mechanism for studied compounds is hydrogen atom transfer (HAT). [•] The results indicate that compounds with adjacent hydroxyl group on phenyl ring are most efficient hydrogen-donor systems. [•] The computational values are in accordance with experimental findings. [ABSTRACT FROM AUTHOR]
