| Outline of Final Research Achievements |
Fibrodysplasia ossificans progressiva (FOP) is a rare congenital disorder of progressive and widespread postnatal heterotopic bone formation in soft tissues. Accordingly, we have screened microbial metabolites for inhibitors of bone morphogenetic protein (BMP) signaling on two types of cell-based assay system with a pathological mutation of FOP. As a result, three novel compounds, designated scopranones, were isolated from the culture broth of Streptomyces sp. BYK-11038. Scopranones have an unusual common structure with two atypical scooplike moieties linked at the tails to form part of a unique 3-furanone ring. In addition, destruxins and citreoviridins were isolated from fungal cultures broths, and lamellolactones and dyssidenins were isolated from sponges.

| Academic Significance and Societal Importance of the Research Achievements |
今回新規化合物として見出したscopranoneは、その新規な構造から有機化学の研究者によって全合成が達成され、構造活性相関研究が進められている。また、生合成研究にも興味が持たれ、遺伝子レベルでの解析も行われていることから、他の研究領域にも注目される化合物を提供できている。さらに、治療法が全く確立されていない難病FOPの予防治療薬の開拓を目的とした本研究は、社会的貢献度の高い内容と考えられる。
