A compound library may include a plurality of conjugate molecules, said conjugates comprising a small organic molecule covalently coupled to a nucleic acid moiety. The nucleic acid moiety may include or consist of 7-deazapurines and/or 7-deaza-8-azapurines, and, optionally, modified pyrimidine nucleotides and/or unmodified pyrimidine nucleotides. Further, a library for screening compounds binding to a target molecule and methods of synthesizing said library is also disclosed.

The disclosure relates to broad spectrum, direct acting antiviral agents. Disclosed is a group of novel nucleoside and nucleotide analogs having a 4-substituted imidazol-2-one heterocycle in place of the pyrimidine base of natural nucleic acid components and their prodrug derivatives (see Formula I).
