Page/Page column 4-5, (2010/02/10)
Anticancer peptides which incorporate furanoid sugar amino acids and compositions made using these peptides are described. Methods for synthesis of the peptides and for preparing the furanoid sugar amino acids are disclosed. The peptides and compositions made using the peptides have pharmacological applications of these peptides especially in the treatment and prevention of cancer and tumors.
Synthesis and structural studies of oligomers of 6-amino-2,5-anhydro-6-deoxy-D-mannonic acid

A novel cycloetherification process involving a facile 5-exo S(N)2-type ring closure by intramolecular opening of a terminal aziridine ring by a γ-hydroxyl group, led to the stereoselective synthesis of 6-amino-2,5-anhydro-6-deoxy-D-mannonic acid (1). Oligomerization of 1 by solution phase peptide coupling methods gave oligomers 2-5. While most of the oligomers, in either protected or deprotected form, did not show any significant secondary structure, octamer 5 (P = H) exhibited a very strong positive band at 216 nm in its CD spectrum in MeOH and TFE, indicating the possibility of the presence of an ordered structure in solution. Its 1H NMR spectra in various polar solvents, however, failed to produce any distinct dispersion of the amide proton chemical shifts. Compounds 1-5 were found to be inactive in hypoglyceamic tests in rats. (C) 2000 Elsevier Science Ltd.
