Outline of Final Research Achievements |
In this study, we searched for new natural products and bioactive natural products by using culture methods that mimics the growth environment of microorganisms such as interactions between microorganisms existing in the same soil, and interactions between animal cells (immune cells) and microorganisms including pathogenic microorganisms. As a result, we isolated new natural products with cell death-inducing and anti-inflammatory effects and several known natural products, and analyzed the mechanisms of action of bioactive natural products.
