It is for Alzheimer’s disease, but the same approach might work (I hope has to work) for PD

From this list of molecules, one drug, ALI6, showed promising results in cell-based experiments.

Jiang and his team cultured mouse brain cells and exposed them to the toxic b-amyloid proteins, then treated some cells with ALI6 and compared levels of cell death between groups. ALI6 treatment almost completely prevented the cell death caused by b-amyloid, suggesting that the drug could eventually be explored to treat Alzheimer’s disease.

ALI6 is a promising candidate. Not only is it non-toxic but it can also move from the bloodstream to the brain, a critical trait for any drug aimed at treating central nervous system disorders such as Alzheimer’s disease. In addition, ALI6 offers a distinct advantage over other treatments.

It would be great if it worked Alzheimer's and Parkinson's too. However, vast amounts of money have been wasted pursuing treatments for amyloid, which is a response to the presence of pathogens, instead of pursuing the pathogens themselves. Not every pathogen causes immediate acute illness. Medicine seems to have a blind spot in this regard.
