Abstract: Disclosed is a method for obtaining a bifunctional complex comprising a display molecule part and a coding part, wherein a nascent bifuntional complex comprising a chemical reaction site and a priming site for enzymatic addition of a tag is reacted at the chemical reaction site with one or more reactants, and provided with respective tag(s) identifying the reactant(s) at the priming site is using one or more enzymes.

Abstract: The present invention relates to a method for generating a second-generation library. In a first step, a library of encoded molecules associated with an identifier nucleic acid comprising codons identifying chemical entities that have participated in the formation of the encoded molecule is provided. In a second step, the library is partitioned and encoded molecules having a certain property are selected. Codons of identifiers of selected encoded molecules are subsequently identified, and a second-generation library is prepared using at least some of the chemical entities coded for by the identified codons. The new focussed library may be used for another partition step to select encoded molecules with a certain property.

Abstract: The present invention is directed to the synthesis of molecules guided b connector polynucleotides (CPNs capable of hybridizing to complementary connector polynucleotides (CCPNs) harbouring at least one functional entity comprising at least one reactive group. At least one of said CCPNs capable of hybridize to at least two CPNs. Each CPN will “call” for one or more CCPNs capable of hybridization to the CPN. Following the formation of a supramolecular hybridization complex comprising a plurality of CPNs and a plurality of CCPNs, the reaction of functional entity reactive groups result I the formation of a molecule comprising covalently linked functional entities. The formation of the molecule involves the transfer of functional entities from one or more “donor CCPNs” to at least on “acceptor CCPN” with which the transferred functional entities were not associated prior to the transfer.

Abstract: A building block having the dual capabilities of transferring genetic information and functional entity precursor to a recipient reactive group is disclosed. The building block may be used in the generation of a single complex or libraries of different complexes, wherein the complex comprises an encoded molecule linked to an encoding element. Libraries of complexes are useful in the quest for pharmaceutically active compounds.
