Figure 2From: Identification of plant-derived natural products as potential inhibitors of the Mycobacterium tuberculosis proteasome Dose response curves of inhibitory activities of MG132, baicalein, pectolinarin, myricetin, hispidulin, isoliquiritigenin and quercetin. The IC50 values were calculated by fitting with the four parameter logistic (4-PL) model: A. MG132 IC50=27.97 μM, R2=0.99. B. baicalein IC50=45.65 μM, R2=0.97. C. pectolinarin IC50=49.96 μM, R2=0.97. D. myricetin IC50=55.39 μM, R2=0.96. E. hispidulin IC50=58.31 μM, R2=0.97. F. isoliquiritigenin IC50=63.90 μM, R2=0.99. G. quercetin IC50=71.29 μM, R2=0.96. R2, adjust R square values. Dose response curves of inhibitory activity were presented. Data are shown as mean ± SD of three independent experiments.Back to article page
