MolPort New Compound Libraries 2015

Enrich your compound collection with diverse compounds made in 2015.

Currently 6.3 million commercially available HTS compounds can be purchased through MolPort. 200,000 of these are new unique compounds added to our database this year. We verified with suppliers which compounds were made in 2015 and filtered them by available quantity and lead time. The result is a set of 160,000 new compounds.

Pre-filtered compound sets

We make these compounds available to our clients as three libraries:

  • Rule of 5 set
  • sp3-enriched set
  • Fragments set

The selection criteria and number of compounds of each library are outlined in Table 1.

Diversity compound sets

For easy sampling of the new chemical space we created three diversity sets. We analyzed and removed compounds that were similar to compounds available prior to 2015. For in-set diversity we clustered compounds by chemical fingerprint with similarity index 0.85 (Tanimoto) and selected the most representative compound from each cluster. Structures that have high negative drug-likeness to registered drugs and high calculated toxicity score (Mutagenic, Tumorigenic, Irritant) were removed from final selection.
