title: Cyclodidemniserinol trisulfate, a sulfated serinolipid from the Palauan ascidian Didemnum guttatum that inhibits HIV-1 integrase.
abstract: [structure--see text] Bioassay-guided fractionation of extracts of the Palauan ascidian Didemnum guttatum led to the isolation of cyclodidemniserinol trisulfate (1) as an inhibitor of HIV-1 integrase, which is an attractive target for anti-retroviral chemotherapy. The structure of cyclodidemniserinol trisulfate (1), the stereochemistry of which was only partially determined, was elucidated by interpretation of NMR and mass spectral data.
