Ugibohlin: A New Dibromo-seco-isophakellin from Axinella carteri

Chemical investigation of a marine sponge, Axinella carteri, collected on a reed slope of Talakanen Island, Phillipines, has afforded the new metabolite ugibohlin (1), along with its known cyclic derivative dibromoisophakellin (2). Structure elucidation of the isolated metabolites involved high-fiel...

Zusammenfassung:	Chemical investigation of a marine sponge, Axinella carteri, collected on a reed slope of Talakanen Island, Phillipines, has afforded the new metabolite ugibohlin (1), along with its known cyclic derivative dibromoisophakellin (2). Structure elucidation of the isolated metabolites involved high-field 2D NMR spectroscopy including 1H−H COSY, HSQC, and HMBC. Revised chemical shift assignments are provided for 2.
