| Outline of Final Research Achievements |
We proposed a new approach, diversity-enhanced extracts, for increasing the diversity of natural product-like compounds. Diversity-enhanced extracts are prepared from chemical reactions that remodel molecular scaffolds directly on extracts of natural resources. The subsequent isolation of each compound produced from such reactions affords a diverse natural product-like library. Direct, three successive chemical reactions were performed on plant extracts containing a large amount of terpenes to prepare diversity-expanding extracts, which were then separated to give more than 20 kinds of phenolic and pyrone-type merotelpenoids. As a result of carrying out extensive biological activity screening for these compounds, bioactive substances such as osteoclast differentiation inhibitory activity were found.
