Solid-phase synthetic route to multiple derivatives of a fundamental peptide unit.

William L Scott et al.

Molecules (Basel, Switzerland), 15(7), 4961-4983 (2010-07-27)

Amino acids are Nature's combinatorial building blocks. When substituted on both the amino and carboxyl sides they become the basic scaffold present in all peptides and proteins. We report a solid-phase synthetic route to large combinatorial variations of this fundamental
