abstract = {Parkinson's disease (PD) is classified as a synucleinopathy
due to the accumulation of protein inclusions rich in the
alpha-synuclein (aSyn) protein. Identifying effective
pharmacological therapies is important to slow the
progression and minimize the symptoms of these diseases.
Cannabis sativa has a diverse chemical profile depending on
its genotype, including several classes of substances, such
as cannabinoids, flavonoids, terpenes, and alkaloids. In
this study, we evaluated the effects of four C. sativa
extracts with different phytocannabinoid chemical profiles
in two cellular models that reproduce alterations in
cellular homeostasis common during the cellular phase of PD
and other synucleinopathies. We used Saccharomyces
cerevisiae strains transformed with plasmid DNA and
genetically modified human cells (H4), both expressing aSyn.
The results showed that all the extracts were antioxidants,
decreasing intracellular oxidation levels and increasing the
number of daughter cells in yeast cells, but did not prevent
mitochondrial damage. Besides, the extracts reduced the
number of intracellular inclusions in H4 cells and increased
the number of cells without inclusions. Phytochemical
characterization revealed extracts rich in
Tetrahydrocannabinol - THC (69.88 $\%),$ Cannabidiol - CBD
(52.64 $\%),$ and Cannabinol - CBN (47.38 $\%$ and 58.64
$\%),$ and we concluded that, regardless of these
percentages, all C. sativa extracts showed protective
biological activity against toxicity caused by
alpha-synuclein production, both in yeast cells and H4
cells.},
