Bile acid-based receptors containing 2,6-bis(acylamino)pyridine for recognition of uracil derivatives

Hydrogen-bonding interactions of steroid-based cyclic and acyclic receptors containing 2,6-bis(acylamino)pyridine with uracil derivatives were studied in CDCl3. Acyclic receptors show better binding behaviour as compared to cholaphanes with uracil derivatives.
