Prestwick Phytochemical Library

Prestwick Phytochemical Library:
A set of small natural molecules
from natural origin

The phytochemical library is a collection of 320 purified compounds, mostly from plants. Rich in diverse chemotypes, compounds were selected by medicinal chemists to fit with follow-up chemistry.

This library is made of various classes of compounds: flavonoids, lignans, alkaloids, quinones, etc…., the compounds originating from randomly selected plants, but all known for having pharmacological activity.
