Pre-plated Diversity Sets

Life Chemicals presents its exclusive Pre-plated Diversity Sets (PS6) composed of a total of 50,000 novel screening compounds with optimal physicochemical properties selected by dissimilarity search from the Life Chemicals HTS Compound Collection of newly synthesized molecules. It has been designed to facilitate phenotypic (cell-based) and target-based high throughput screening (HTS) efforts by providing access to a collection of structurally-diverse small molecules in a convenient manner.

For your convenience, there are Diversity Subsets of 5,000, 10,000, 15,000, and 20,000 compounds with no structure overlap. They are complementary and can be combined to create more extensive diverse screening libraries (e.g., 30,000, 40,000, and up to 50,000 compounds in total).

Moreover, we also offer additional readily-available screening sets: Pre-plated Diversity Sets PS5 (50,000 compounds) and PS4 (20,000 compounds), combinable into 120,000 non-overlapping compound superset.

The Pre-plated Diversity Sets and its Subsets are ideal tools for drug discovery projects that require a wide range of chemical structure dissimilarity and quality drug-like and lead-like compounds to screen against new or validated biological targets from different classes, or where little information is available on a targeted protein structure.

Key features:

  • Mean Tanimoto value of the Diversity Set PS6 is 0.409 with even lover values in the subsets (calculated with ECFP fingerprints)
  • No overlap with our previous Diversity Sets PS4 and PS5
  • Lipinski Rule of Five and Veber criteria compliant compounds
  • No reagents. No reactive and unstable molecules
  • PAINS filters families A, B, C applied
  • Lilly MedChem Rules compliant


  • 10mM solutions in DMSO
  • Different volumes available: 10 uL, 25 uL, 50 uL
  • 384-well microplates (Greiner bio-one ref: 781280 or 784201)
  • 320 compounds per plate; 1-2, 23-24 columns empty

More parameters of the Diversity Subsets are listed in Table 1 below. The compound distribution for each parameter is illustrated in Figure 1.

Screening compounds from the Pre-plated Diversity Set also belong to one or more of the proprietary Targeted and Focused Screening Libraries designed by Life Chemicals. The compound distribution between the main types of screening compound libraries is shown in Fig. 2. Fig. 3 illustrates a few representative examples of final compounds in the Pre-plated Diversity Set and how they relate to the in-house premium scaffolds through different intermediate Building Blocks.
