  Structural Similarity Between NPASS Natural Products and NPD580Similarity is measured using the Tanimoto coefficient (Tc) , which compares the binary fingerprints of two molecules. Tc is calculated as the intersection divided by the union of '1' bits in the fingerprints, ranging from 0 to 1, with 1 indicating highest similarity.
Tanimoto coefficient is calculated based on PubChem 881-bit substructure fingerprints.
  Similar Natural Products High Similarity: Tc>=0.85; Intermediate Similarity: 0.7 <= Tc < 0.85; Remote Similarity: 0.5 <= Tc < 0.7
