  • Title: Two new C22 1,2-dioxane polyketides from the marine sponge Acarnus cf. bergquistae.
    Author: Yosief T, Rudi A, Wolde-ab Y, Kashman Y.
    Journal: J Nat Prod; 1998 Apr; 61(4):491-3. PubMed ID: 9584404.
    Abstract:
    Two new cyclic peroxide-containing polyketide C22 methyl esters, peroxyacarnoic acid methyl esters A and B, 1 and 2, have been isolated from the Red Sea marine sponge Acarnus cf. bergquistae. Both 1 and 2 are proposed to contain a single 1,2-dioxane ring, an eneyne functionality, and a terminal double bond or triple bond, respectively. The structures were elucidated mainly through 1D and 2D NMR spectral analysis.
