Anesthesia or seizure-like behavior? The effects of two Amazonian plants, Acmella oleracea and Piper alatabaccum in zebrafish (Danio rerio).
    Brazilian journal of biology = Revista brasleira de biologia, 2022, Volume: 82

    Currently, available fish anesthetics can produce important side effects, including respiratory arrest and distress. Easy-to-implement alternatives with low toxicity are needed to ensure fish health as well as to help artisanal fisheries and fish sellers in handling and transporting fishes, and native plants seems to be the best alternative. We aimed to implement an anesthetic protocol using crude ethanolic extracts from flowers and leaves of two Amazonian plants, the Acmella oleracea and Piper alatabaccum. We first tested the extracts for anesthesia, using the zebrafish as model. Even though in some treatments the animals apparently entered deep anesthesia, many of them presented aberrant behaviors and even died. Thus, we performed new experiments testing the extracts effects on seizure-like behaviors of the fish. Only the leaf extract of A. oleracea has potential effects for fish anesthesia. Both the flower extract from this plant and the leaf extract from P. alatabaccum induced seizure-like behavior in the animals. In conclusion, besides bringing a possible new anesthetic protocol for fish, our work draws attention for the neurotoxic effects the anesthetic solutions may cause, since several studies defend other Piper species as anesthetic for fish and A. oleracea flowers' extract was already pointed as fish anesthetic.

Piplartine, an amide alkaloid from Piper tuberculatum, presents anxiolytic and antidepressant effects in mice.
    Phytomedicine : international journal of phytotherapy and phytopharmacology, 2007, Volume: 14, Issue:9

    In the present work, we studied the effects of piplartine (PIP), an amide alkaloid isolated from the roots of Piper tuberculatum (Piperaceae), in the elevated plus maze, open field, rota rod, pentylenetetrazole (PTZ)-induced seizures, and forced swimming tests, in mice (Swiss, male, 25 g) to assess anxiolytic, sedative, muscle relaxant, anticonvulsant and antidepressant effects, respectively. Results showed that PIP (50 and 100 mg/kg, i.p.), similarly to diazepam, significantly increased not only the number of entrances (100% and 66%, respectively) but also the time of permanence in the open arms (104% and 199%, respectively), indicating that PIP presents an anxiolytic activity. Both effects were completely blocked by the previous administration of flumazenil what suggests the involvement of benzodiazepine type receptors. In the open field test, although PIP did not alter the number of crossings, it significantly increased grooming (103% and 119%) and rearing (60% and 23%), at the doses of 50 and 100 mg/kg respectively, as compared to controls. However, in the rota rod test, PIP was devoid of effect. Although in the PTZ-induced convulsion test, PIP did not alter the latency time for the onset of the first convulsion, as compared to controls, it significantly reduced in 58% and 60%, respectively, the animal's latency time to death. Furthermore, a significant and dose-dependent decrease in the immobility time, as evaluated by the forced swimming test, was observed after PIP administration (41% and 75% decrease, at the doses of 50 and 100 mg/kg, respectively), suggesting an antidepressant effect, similarly to that observed with imipramine, a classical antidepressant drug used as standard. In conclusion, we showed that PIP presents significant anxiolytic and antidepressant activities, making this drug potentially useful in anxiety and depression.
