NP-Scout

NP-Scout is a free web service for the:
  • Identification of natural products in large molecular libraries
  • Quantification of natural product-likeness of small molecules
  • Visualization of atoms and areas in small molecules characteristic of natural products or synthetic molecules (based on similarity maps)

NP-Scout utilizes random forest classifiers trained on data sets consisting of more than 265k natural products and synthetic molecules.

For more information, see the About page.
