Abstract

In this paper, the anti-cancer activity and molecular mechanisms of the isomers of AD-1 and AD-2 (20()-AD-1, 20()-AD-2, 20()-AD-1 and 20()-AD-2) were investigated. The results indicated that all of the four compounds obviously suppressed the viability of various cancer cells, and the anti-cancer activity of 20()-AD-1 and 20()-AD-2 was significantly better than 20()-AD-1 and 20()-AD-2, especially for gastric cancer cells (BGC-803). Then, the differences in the anti-cancer mechanisms of the isomers were investigated. The data showed that 20()-AD-1 and 20()-AD-2 induced apoptosis and decreased MMP, up-regulated the expression of cytochrome C in cytosol, transferred Bax to the mitochondria, suppressed oxidative phosphorylation and glycolysis and stimulated reactive oxygen species (ROS) production. Apoptosis can be attenuated by the reactive oxygen species scavenger N-acetylcysteine. However, 20()-AD-1 and 20()-AD-2 barely exhibited the same results. The results indicated that 20()-AD-1 and 20()-AD-2 suppressed cellular energy metabolism and caused apoptosis through the mitochondrial pathway, which ROS generation was probably involved in. Above all, the data support the development of 20()-AD-1 and 20()-AD-2 as potential agents for human gastric carcinoma therapy.
