Our research group aims to utilize biological resources from tropical and subtropical plants for environmental conservation and human health improvement. We explore the stress tolerant mechanism of tropical plants to develop stress-tolerant crops, and to increase agricultural productivity. Our focus has bee on the biological function of terpenoids in mangrove trees. These lipids increased with salt stress, and our research group has proposed its putative role in protecting mangrove trees from salt stress for the first time. Another research topic is the application of biological activity of natural resources to treat the lifestyle-related diseases such as obesity, atherosclerosis and cancer. One recent study put much focus on the tumor selective cytotoxicity of natural compounds in tropical and subtropical plants. Among these, nitidine has been isolated and characterized as a cancer specific anti-cancer agent. Continuing research work in this field may open up the possibility for development of safe cancer chemotherapy with low side effects.
