Mechanistic Set

11 x 96-Well Plates


The mechanistic diversity set, which consists of 879 compounds, was derived from the 37,836 open compounds that have been tested in the NCI human tumor 60 cell line screen. In contrast to the original diversity set of 1,990 compounds, which was chosen on the basis of structural diversity, this mechanistic diversity set was chosen to represent a broad range of growth inhibition patterns in the 60 cell line screen, based on the GI50 activity of the compounds. Compounds that have been tested in the 60 cell line screen were clustered using the FASTCLUS procedure in the SAS statistical package. This algorithm is based on MacQueen's k-means algorithm, which minimizes the sum of squared distances from the cluster means. The procedure resulted in 1272 clusters. A single representative compound from each cluster, for which an adequate supply of material was available, was chosen. Some clusters are not represented in the set, as insufficient material was available.  All compounds in this set are 1mM in 100% DMSO.


Diversity Set III

20 x 96-Well Plates


The diversity set was derived from the almost 140,000 compounds available on plates. Only compounds for which at least one gram of material is available were considered. This was done to allow a large number of copies to be made and to assure adequate amounts to supply refill requests. The 80,000 compounds meeting this criterion were then reduced to the final set using the program Chem-X (Oxford Molecular Group). Chem-X uses defined centers (hydrogen bond acceptor, hydrogen bond donor, positive charge, aromatic, hydrophobic, acid, base) and defined distance intervals to create a particular finite set of pharmacophores. 3-point pharmacophores were used with the default settings, resulting in almost 1,000,000 possible pharmacophores. The selection protocol considers each molecule, all its pharmacophores and each of its conformational isomers. During the generation of the diversity set, the pharmacophores for any candidate compound are compared to the set of all pharmacophores found in structures already accepted into the set. If the current structure has more than 5 new pharmacophores, it is added to the set. An additional objective with the NCI Diversity Set III was to create a diverse set of compounds that were amenable to forming structure-based hypotheses. Thus, molecules that were relatively rigid, with 5 or fewer rotatable bonds, having a tendency to be planar, 1 or less chiral centers, and pharmacologically desirable features (i.e., did not contain: obvious leaving groups, weakly bonded heteroatoms, organometallics, polycyclic aromatic hydrocarbons, etc.) were given priority in the final selection. This resulted in a set of 3046 compounds. This set was sent to the Molecular Libraries Small Molecular Repository where they were checked for purity via LC/Mass Spec. Only compounds with a purity of 90% or better by this method were accepted. This resulted in a final set of 1597 compounds. All compounds in this set are 10mM in 100% DMSO.

This set was created in response to numerous drug discovery research groups that expressed a desired to study a variety of scaffold structures having multiple functional groups.
