| Outline of Final Research Achievements |
The project aimed to discover novel anti-cancer agents by employing an anti-austerity strategy and to elucidate the mechanism of action through protein and metabolome analysis. Extensive investigation on the anti-cancer activity of the active principals from the medicinal plants Ferula hezarlalehzarica, Ancistrocladus abbreviatus, Calotropis gigantea, Artemisia vulgaris, Anneslea fragrans, Ancistrocladus ealaensis, Bosenbergia pandurata、Uvaria dac, Chamaecyparis obtusa, Citrus hystrix, Derris scandens, Callistemon citrinus has been investigated. The investigation of the mechanism of action of the selected novel anticancer agents was accomplished. In particular, the novel compound, a 5,8-linked naphthyl isoquinoline alkaloid Ancistrolikokine E3 was discovered as a promising anticancer agent that eliminates cancer cells' tolerance to nutrient starvation. Ancistrolikokine E3 was found to inhibit Akt/mTOR/Autophagy Signaling Pathway and causes pancreatic cancer cell death.
