Brominated polyacetylenes from the Philippines sponge Diplastrella sp.
Five novel brominated polyacetylenic diols, diplynes A-E (2-6), and three sulfated analogues, diplyne A 1-sulfate (7), diplyne C 1-sulfate (8), and 2-deoxydiplyne D sulfate (9), were isolated from the Philippines sponge Diplastrella sp. by employing bioassay-guided fractionation using the HIV-1 integrase inhibition assay. The novel metabolites were characterized by interpretation of spectroscopic data.
