 Ronald,
 I think you should give a look at the following publication:

 ConCept: de Novo Design of Synthetic Receptors for Targeted Ligands

 Abstract:
 Low-molecular-weight receptors that bind targeted guest molecules have a wide
 range of potential applications but are difficult to design. This paper
 describes an evolutionary method for computer-aided design of such receptors
 that works by linking together chemical components from a user-defined library
 around a stable conformation of the targeted ligand. The software can operate in
 three modes: de novo design, in which it builds a wide variety of receptors from
 small components; macrocycle design, in which it builds homopolymeric
 macrocycles around the ligand; and elaboration of an existing receptor
 structure. The top candidates generated by the automatic construction process
 are further studied with detailed affinity calculations whose validity is
 supported by prior studies of experimentally characterized host-guest systems.
 All three modes of operation are illustrated here through the design of novel
 adenine receptors.
 HTH,
 Roberto
