Gymnastatins F−H, Cytostatic Metabolites from the Sponge-Derived Fungus Gymnascella dankaliensis
摘要:
Gymnastatins F - H (2-4) and gymnamide ( 5) have been isolated from the mycelial MeOH extract of the Halichondria sponge-derived fungus Gymnascella dankaliensis. Their stereostructures have been established on the basis of spectroscopic analyses using 1D and 2D NMR techniques. The stereochemistry of gymnastatin H ( 4) was determined by its synthesis. Among these compounds, gymnastatins F ( 2) and G ( 3) possess a unique bicyclo[3.3.1] nonane ring as natural products, and they were found to exhibit potent growth inhibition against the P388 cancer cell line.
A compound of general formula (I), wherein Y, W, R1, R2, R3, R4, R5, R6, R7, R8, R9, R10, R11, and the dashed lines take various meanings, for use in the treatment of cancer.
