摘要

An amino-functionalized 2-deoxystreptamine (2-DOS) mimic was conjugated by an amide bond to a neamine moiety containing a carboxylic acid in ring II. A library of A-site RNA and its mutants was prepared to examine RNA binding characteristics of the additional 2-DOS moiety attached to neamine. The 2-DOS mimic conjugated to the neamine increased binding affinity up to 200-folds compared to that of neamine. The conjugate binds to native A-site RNA and its mutants with up to 6-fold difference in sequence selectivity.Copyright © 2011 Elsevier Ltd. All rights reserved.
