^aThe IC₅₀ values are shown as the mean for at least two experiments.

^bAnti-proliferative activities were determined by(3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) tetrazolium (MTT) reduction method.

^cAnti-proliferative activities were determined by CCK-8 method.

ND: not detected.
