Title:
HETEROCYCLIC COMPOUNDS, COMBINATORIAL LIBRARIES THEREOF AND METHODS OF SELECTING DRUG LEADS
Document Type and Number:
WIPO Patent Application WO2003059876
Kind Code:
A3
Abstract:
The present invention provides new heterocyclic compounds that have a relatively flexible backbone. These compounds may be used to produce new combinatorial libraries that will permit screening for lead compounds and selection of drug candidates for a variety of uses in human medicine, veterinary medicine and in agriculture. The members of libraries provided by the invention differ from each other (in addition to the conventional chemical and positional diversity attained by the different substituents on the ring) in two novel aspects : (a) the ring size; and (b) the chirality of the substituents on the ring. This leads to conformational diversity and flexibility that allows the selection of the most active compound, not only on the basis of the nature and proper arrangement of the substituents attained by the known chemical and positional diversity, but also based on the ability to undergo conformational complementarity attained by the conformational diversity. The present invention further provides combinatorial libraries comprising a plurality of the heterocyclic compounds of the present invention, and methods of screening the combinatorial libraries for compounds having a beneficial biological effect. The screening methods provided herein may be automated and/or computerized, for example by using a computer program to virtually screen the combinatorial libraries in order to identify compounds that are predicted to adopt bioactive conformations that will give rise to the desired biological effect.
