Synthesis of Carbohydrate-Templated Amino Acids and Methods of Using Same

The present invention generally relates to tetrahydropyranyl-derivatized amino acids, their syntheses and their incorporation into peptides and peptidomimetics. The tetrahydropyran moiety constrains the side chain of an amino acid, thereby providing a molecule that may act as a sugar- or amino acid-mimetic as well as a scaffold for combinatorial synthesis.

Synthesis of glucose-templated lysine analogs and incorporation into the antimicrobial dipeptide sequence kW-OBn

The synthesis of two glucose-templated (GlcT) lysine analogs GlcTK and GlcTk in which the side chain of d- and l-lysine (k and K) is conformationally constrained via incorporation into a d-glucose scaffold is described. A key-step in the synthesis is a high yielding, reductive ring opening of an exocyclic glucose-derived epoxide to form a α-hydroxy ester that can be converted into GlcTK and GlcTk. To demonstrate the use of these building blocks in peptide synthesis, we replaced d-lysine in the antimicrobial dipeptide sequence kW-OBn (W = l-tryptophan) and determined the antibacterial activity against various gram-positive and gram-negative organisms. Our results show that the replacement of d-lysine by unprotected GlcTk in dipeptide kW-OBn results in reduced antibacterial activity.

Synthesis of sugar-lysine chimera with integrated gluco-configured 1,3-hydroxyamine motif

The paper describes the synthesis of glucose-configured sugar-lysine chimeras in which the side chain of lysine is conformationally constrained via incorporation into a D-glucose scaffold. Key step in the synthesis is a high-yielding, reductive ring opening of an exocyclic glucose-derived epoxide to form an α-hydroxyester that can be converted into chimeric sugar-lysine analogues. To demonstrate the use of these novel chimeric sugar-lysine building blocks in peptide coupling, we replaced D-lysine in the antimicrobial dipeptide sequence kW by a D-glucose-D-lysine chimera.
