Abstract

Alzheimer's disease (AD), a progressive neurodegenerative disorder of the aged brain with no known cause or cures, has become a major medical and social problem for industrialized countries. Cerebral deposition of amyloid-β peptide (Aβ) is a critical feature of AD. The use of medicinal plants as an alternative form of prevention, or even as a possible treatment of AD, is therefore interesting areas of research. Sesquiterpene lactones and a sesquiterpene alcohol are compounds found in H. brasiliense that have several anti-oxidative and anti-inflammatory effects. In the present study, we investigated whether these compounds have neuroprotective effects in an amyloid-β peptide-induced Alzheimer's disease mouse model. Mice were injected with Aβ1-42 peptide intracerebroventricularly and were subsequently injected (i.c.v.) with 1µg/site of IGM-A (15-acetoxy-isogermafurenolide), IGM-H (15-hydroxy-isogermafurenolide), PDA (Podoandin), EHP (1,2-epoxy-10α-hydroxy-podoandin), HDS (13-hydroxy-8,9-dehydroshizukanolide), and ARD (aromadendrane-4β,10α-diol). Seven days after treatments the animals had their memory tested in the inhibitory avoidance. After the behavioral testing of animals the brains were removed and subjected to biochemical tests for oxidative stress. The results showed that ARD, HDS and PDA significantly ameliorated the Aβ1-42 peptide-induced memory impairment in the passive avoidance task (P<0.05). In addition, GSH activity was increased while the TBARS levels were decreased by treatment with these compounds. These results suggest that these compounds inhibit the cognitive deficit of animals induced peptide amyloid and may be potential candidates for Alzheimer's disease therapy.

  • The neuroprotective effects of the tested compounds were more correlated with the existence of the guaiane ring than with the presence of the lactone ring.

    “However, the neuroprotective effects possessed by these tested compounds were found more correlated to the existence of the guaiane ring in comparison to the presence of the lactone ring for which mechanism of action is described by Michael-type nucleophilic addition.”
  • ARD, HDS, and PDA isolated from Hedyosmum brasiliense ameliorated Aβ peptide-induced memory impairment in passive avoidance models (p < 0.05).

    “During the investigation, it was observed that aromadendrane-4β,10α-diol (ARD), 13-hydroxy-8,9-dehydroshizukanolide (HDS) and podoandin (PDA), efficiently ameliorated the Aβ peptide-induced memory impairment in models of the passive avoidance task (p < 0.05).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
