Hesperine, a new imidazole alkaloid and α-synuclein binding activity of 1-methyl-1,2,7,8-tetrahydro-2,8-dioxoadenosine from the marine sponge Clathria (Thalysias) cf. hesperia

| Summary: | During a high-throughput screen of 300 Australian marine invertebrate extracts, the extract of the marine sponge Clathria (Thalysias) cf. hesperia was identified with α-synuclein binding activity. The bioassay-guided purification of this extract resulted in the isolation of 1-methyl-1,2,7,8-tetrahydro-2,8-dioxoadenosine (2) as the α-syn binder along with one new compound, hesperine (1), and five known compounds, indole-3-carboxaldehyde (3), (Z)-2′-demethylaplysinopsin (4), 2-amino-4′-hydroxyacetophenone (5), 4-hydroxybenzoic acid (6) and 4-hydroxybenzaldehyde (7). Herein, we report the structure elucidation of hesperine (1) and α-syn binding activity of 1-methyl-1,2,7,8-tetrahydro-2,8-dioxoadenosine (2) |
