(A) Copper chelation assay of CMT-308 measured by reduction in absorbance at 632 nm; kojic acid (KA) at 0.5 mM was used as the positive control; (B) effect of CMT-308 on α-glucosidase enzyme activity, measured with pNG substrate; (C) antioxidant activity of CMT-308 measured by DPPH radical scavenging assay with ascorbic acid (AA) used as positive control at 2.5 µg/mL (~14 µM); * p < 0.05 and # p < 0.01 vs. Ctrl; one-way ANOVA with Dunnett’s test; data are mean ± SD of triplicate determinations.
