A new dimeric acylphloroglucinol derivative, andinin A (1), was isolated from the underground plant parts of Hypericum andinum, along with three known dimeric acylphloroglucinols, uliginosin A (2), uliginosin B (3), and isouliginosin B (4). The structure of 1 was elucidated using 1D and 2D NMR and MS experiments and by comparison with previously reported(More)
Uliginosin B is a natural phloroglucinol derivative, obtained from Hypericum species native to South America. Previous studies have shown that uliginosin B presents antidepressant-like and antinociceptive effects. Although its mechanism of action is still not completely elucidated, it is known that it involves the activation of monoaminergic(More)
Uliginosin B (ULI) is a natural acylphloroglucinol that has been proposed as a new molecular scaffold for developing analgesic and antidepressant drugs. Its effects seem to be due to its ability to increase monoamines in the synaptic cleft by inhibiting their neuronal uptake without binding to their respective transporters, but its exact mode of action is(More)
