An endogenous nuclear enzyme, RNase H, is an important component in determining the efficacy of antisense oligodeoxynucleotides (ODNs). In an effort to improve the potency of antisense ODNs, conjugates with three different nuclear targeting signal peptides were prepared. These short

A novel method is described for the cyclization of peptides--or segments of polypeptides--which requires a free N-terminal alpha-amino group and a distal amino acid residue containing a nucleophilic side chain. The reaction is conducted in two steps, both in the
