Structure-activity relationship analysis of imprimatinC1.
(a) Molecular structures of the imprimatinC1 derivative compounds. (b) Bioactivities of the compounds regarding pathogen-induced cell death in Arabidopsis cells in suspension. Each cell death rate is shown as a value normalised to the mean value in mock treatments with the pathogen for each experimental group. Data are expressed as the mean ± SD (n = 4).
