| Abstract
| - Four new indoles, ancorinolates A−C and bis-ancorinolate B, which contain sulfamate and sulfategroups, were isolated from the aqueous extract of the sponge Ancorina sp. In addition, ancorinazole,an indolo[3,2-a]carbazole also possessing sulfamate and sulfate groups, was isolated from twoseparate New Zealand collections of Ancorina sp. Ancorinazole is the first indolo[3,2-a]carbazoledescribed as a natural product. Ancorinolates A (1) and C (3) showed weak HIV-inhibitory activityin the XTT-based, anticytopathicity assay.
