NF-κB (p65 subunit) DNA binding capacity in nuclear extracts of HL60R cell line. The cells were treated for 24 h with compounds at the corresponding IC₅₀ values. Results are expressed as arbitrary units/μg protein of HL60R nuclear extracts and the mean ± SE of three independent observations, * p < 0.01 versus control; ^a p < 0.05: AO derivates versus precursor, ^A p < 0.05: LU derivates versus precursor (one-way ANOVA followed by Tukey’s test).
