Searching for pharmacophores in large coordinate data bases and its use in drug design.

Pharmacophores, three-dimensional arrangements of chemical groups essential for biological activity, are being proposed in increasing numbers. We have developed a system to search data bases of three-dimensional coordinates for compounds that contain a particular pharmacophore. The coordinates can be derived from experiment (e.g., Cambridge Crystal Database) or be generated from data bases of connection tables (e.g., Cyanamid Laboratories proprietary compounds) via the program CONCORD. We discuss the results of searches for three sample pharmacophores. Two have been proposed by others based on the conformational analysis of active compounds, and one is inferred from the crystal structure of a protein-ligand complex. These examples show that such searches can identify classes of compounds that are structurally different from the compounds from which the pharmacophore was derived but are known to have the appropriate biological activity. Occasionally, the searches find bond "frameworks" in which the important groups are rigidly held in the proper geometry. These may suggest new structural classes for synthesis.[1]
