Structure−Function Studies on a Synthetic Guanosine Receptor That Simultaneously Binds Watson−Crick and Hoogsteen Sites
摘要:
A series of receptors (11-16) designed to simultaneously bind the Watson-Crick and Hoogsteen sites of guanosine were synthesized, and their binding of guanosine tri-O-pentanoate (32) was probed via H-1 NMR complexation studies in 5% DMSO-d(6)-chloroform-d. The guanosine receptors were synthesized with aminonaphthalene or aminoquinoline auxiliary groups tethered to N-4 of cytosine via a methylene or carbonyl group. A structure -function relationship was established allowing energetic contributions made by components of nucleoside analogues to be probed and more general design rules formulated that may guide the development of more efficacious DNA bases.
