Resveratrol’s neglected siblings


We have previously discussed the powerful antioxidant Resveratrol, and reviewed the research suggesting that it could be beneficial in the context of Parkinson’s disease (Click here to read that post).

I have subsequently been asked by several readers to provide a critique of the Parkinson’s-associated research focused on Resveratrol’s twin sister, Pterostilbene (pronounced ‘Terra-still-bean’).

But quite frankly, I can’t.

Why? Because there is NO peer-reviewed scientific research on Pterostilbene in models of Parkinson’s disease.

In today’s post we will look at what Pterostilbene is, what is known about it, and why we should seriously consider doing some research on this compound (and its cousin Piceatannol) in the context of Parkinson’s disease.

So this is likely to be the shortest post in SoPD history.


Because there is nothing to talk about.

There is simply no Parkinson’s-related research on the topic of today’s post: Pterostilbene. And that is actually a crying shame, because it is a very interesting compound.

What is Pterostilbene?

Like Resveratrol, Pterostilbene is a stilbenoid.

Stilbenoids are a large class of compounds that share the basic chemical structure of C6-C2-C6:

Resveratrol is a good example of a stilbenoid. Source: Wikipedia

Stilbenoids are phytoalexins (think: plant antibiotics) produced naturally by numerous plants. They are small compounds that become active when the plant is under attack by pathogens, such as bacteria or fungi. Thus, their function is generally considered to part of an anti-microbial/anti-bacterial plant defence system for plants.

The most well-known stilbenoid is resveratrol which grabbed the attention of the research community in a 1997 study when it was found to inhibit tumour growth in particular animal models of cancer:
