Abstract

Abstract: Receptors based upon 3, 6-diaminocarbazole have been synthesized that bind to adenosine derivatives with an interaction energy of approximately 8 kcal/mol in CDC13 and over 3 kcal/mol in CD30D. The purine nucleus is bound within a cavity by simultaneous Watson-Crick and Hoogsteen base-pairing, hydrogen bonding to N3, and stacking on both of its aromatic faces. Hydrogen bond interactions can be estimated at approximately 0.5- ...
