title: Triangulynes A-H and trangulynic acid, new cytotxic polyacetylenes from the marine sponge Pellina triangulata.
abstract: Nine new polyacetylenes, triangulynes A-H (1-8) and triangulynic acid (9), have been isolated from the marine sponge Pellina triangulata (Oceanapiidae) through cytotoxicity-guided fractionation. Structural elucidations and stereochemistry assignments were based on chemical and spectral studies.
