Abstract:
A new method of designing and generating compounds having an increased probability of being drugs, drug candidates, or biologically active compounds, in particular having a therapeutic utility, is disclosed. The method consists of identifying a group of bioactive compounds, preferably of diverse therapeutic uses or biological activities and built on a common building block. In this group of compounds, side chains modifying the building block are identified and used to generate a second set of compounds according to the proposed methods of "hybridization", "single substitution" or "incorporation of frequently used side chains". If the compounds in the second set built on the same building block contain an unusually large number of drugs, preferably with diverse therapeutic uses or biological activities, they constitute a "hot spot". A focused combinatorial library of the "hot spot" is then generated, preferably by methods of combinatorial chemistry, and compounds of this library are screened for a variety of therapeutic uses or biological activities. The method generates drugs, drug candidates, or biologically active compounds with a high probability, without requiring any prior knowledge of biological targets.

Abstract:
Compounds are provided that bind allosterically to the catalytic domain of MMP-13 and comprise a hydrophobic group, first and second hydrogen bond acceptors and at least one, and preferably both, of a third hydrogen bond acceptor and a second hydrophobic group. Cartesian coordinates for centroids of the above features are defined in the specification. When the ligand binds to MMP-13, the first, second and third (when present) hydrogen bond acceptors bond respectively with Thr245, Thr247 and Met 253, the first hydrophobic group locates within the S1' channel of MMP-13 and the second hydrophobic group (when present) is relatively open to solvent. The compounds specifically inhibit the matrix metalloproteinase-13 enzyme and thus are useful for treating diseases resulting from tissue breakdown, such as heart disease, multiple sclerosis, arthritis, atherosclerosis, and osteoporosis.
