The MOLECULES approach is based on the traditional Split-and-combine Strat egy for Synthesis of combinatorial libraries comprising two TECHNICAL FIELD OF THE INVENTION or more Synthetic Steps. Plurality nucleic acid templates are used, each having at one end a chemical reactive site and 0001. The present invention relates to a method for dispersed throughout the Stand a plurality of codons regions, Synthesising templated molecules. The method implies a each of Said codon regions in turn Specifying different high local concentration of reactive groups intended to codons. Separately, each of the Strands, identified by a first participate in a formation of a linkage, thus increasing the codon region, is reacted at the chemical reaction sites with probability of linkage formation. The invention also relates Specific Selected reagents. Subsequently, all the Strands are to a library, that is a plurality of templated molecules, pooled and Subjected to a Second partitioning based on a wherein each of the. templated molecules are attached to the Second codon region. The split-and-combine method is template which directed the synthesis thereof. conducted an appropriate number of times to produce a library of typically between 10 and 10 different com BACKGROUND pounds. The Split-and-combine method is cumberSome and 0002 The generation of molecules carrying new proper generates only a relatively Small library. ties remains a challenging task. Recently, a number of 0006 Gartner ZJ and Liu D R (J. Am. Chem.

These approaches allow the more than a single chemical entity is to participate in the researcher to generate and Screen a huge number of mol formation of an encoded molecule, it is necessary to have a ecules in a short time. This should lead to better molecules building block Spaced from a reactive site of the template by carrying the desired properties. one or more codons. Typically, the distance between the 0003. The central dogma of biology describes the one building block and the reactive site of the template amounts way flow of information from DNA to RNA to protein. to Several nucleotides, e.g. 30 nucleotides, which implies Recently, methods Such as phage display, peptides-on-plas that the reaction at the largest distance from the template mids, ribosome display and mRNA-protein fusion have been reactive site is less promoted relative to a chemical entity developed, allowing the transfer of information from the carried by a building block annealed to a codon next to the level of protein/peptide to RNA or DNA. This has enabled reactive Site. the use of molecular evolution to be applied on huge numbers of peptides that are exposed to an enrichment 0007. The present invention aims at suggesting a solution process, where after the enriched pool of molecules for increasing the local concentration of reactants to promote (enriched for a particular feature, Such as binding to receptor the probability of a reaction. protein) are amplified, by exploiting information flow from the peptide to DNA and then amplifying the DNA.
