Terminal Phosphate Group

Synthesis of a novel cyanoethyl-type linker suitable for the solid-phase synthesis of oligodeoxynucleotides possessing terminal 3'-phosphate group is described. Since the linker is a 2-substituted 2-cyanoethanol, the release of the synthesized oligonucleotide from the solid support is accomplished by β-elimination in the ammonia deprotection step.

Scaffold Diversity

There is considerable interest in the development of libraries of non-peptidic macrocycles as a source of ligands for difficult targets. We report here the solid-phase synthesis of a DNA-encoded library of several hundred thousand thioether-linked macrocycles. The library was designed to be highly diverse with respect to backbone scaffold diversity and to minimize the number of amide N-H bonds, which compromise cell permeability. The utility of the library as a source of protein ligands is demonstrated through the isolation of compounds that bind streptavidin, a model target, with high affinity.
