Abstract: An improved method for the prevention of the inactivation of natural killer (NK) cells and the enhanced activation of NK cells in the presence of monocytes using a combination of a natural killer cell activator and a compound effective to inhibit the production or release of intracellular hydrogen peroxide, or a hydrogen peroxide scavenger, is disclosed. The method is useful, for example, in the treatment of solid tumors, metastases and viral infection.

Abstract: There are disclosed alpha-helix mimetics and methods relating to the same for imparting or stabilizing alpha-helicity to a peptide or protein. In one aspect, the alpha-helix mimetics contain eleven- to fourteen-membered rings covalently attached at the end or within the length of the peptide or protein. The alpha-helix mimetics render the resulting peptide or protein more stable with regard to thermal stability, as well as making the peptide or protein more resistant to proteolytic degradation. In addition, the alpha-helix mimetics may be used in standard peptide synthesis protocols.
