A Dde-based carboxy linker for solid-phase synthesis
摘要:
The Dde-derived carboxy protecting group, 4-{N-[1-(4,4-dimethyl-2,6-dioxocyclohexylidene)-3-melhylbutyl]amino}benzyl ester (ODmab) has been developed into a carboxy functional linker. The stability of the linker to standard acid and base conditions employed in Fmoc/tBu SPPS has been demonstrated and its utility illustrated by the construction of model peptides, Leu-enkephalin and Human Angiotensin II.

the convenient assembly of two peptidechains as a single “pro”‐peptide on the same solidsupport. Following the peptide cleavage and post‐synthetic modifications, this bis‐linker tether can be removed in one‐step by chemical means. This method was used to synthesize a drug delivery‐cargo conjugate, TAT‐PKCi peptide, and a two‐disulfide bridged heterodimeric peptide, thionin (7‐19)‐(24‐32R), a thionin

N-1-(4,4-dimethyl-2,6-dioxocyclohexylidene)ethyl (Dde) linker for the solid-phasesynthesis of oligosaccharides is described. The oligosaccharide products can be cleaved from the resin by hydrazine, ammonia or primary amines, but the linker is stable under the conditions of oligosaccharidesynthesis. The first sugar can be attached to the resin linker via a vinylogous amide bond, or by ether linkage using
