Abstract

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.

摘要

通过使用HIV-1整合酶抑制试验进行生物测定指导的分级分离，从菲律宾海绵双盘海绵属（Diplastrella sp.）中分离出五种新型溴化聚乙炔二醇，双炔A-E（2-6），以及三种硫酸化类似物，双炔A 1-硫酸盐（7）、双炔C 1-硫酸盐（8）和2-脱氧双炔D硫酸盐（9）。通过光谱数据分析对这些新型代谢产物进行了表征。
