Abstract: A method for constructing a spiral tube support apparatus used in countercurrent chromatography, improvements to countercurrent chromatography tube support design, and methods of using the improved countercurrent chromatography apparatus are described. The spiral tube support apparatus may be constructed by a shape forming process such as a three dimensional printing process that in turn uses a laser sintering technique, and can be made out of any easily formed material. Shape changes on both the tube support and the top improve the performance of the tube support and ease of manufacturing. The improved tube support and new method of creation permit use in both micro or macro scale preparations and use in small or large molecule preparations. In particular, specific solvent systems are described that permit purification of proteins.

Abstract: This invention is directed to the analogs of viscosin, pharmaceutical compositions thereof and to methods of using viscosin and analogs thereof as biosurfactants and as antibacterial, antiviral and antitrypanosomal therapeutic compounds. In particular, compositions that inhibit the growth of the pathogens Mycobacterium tuberculosis, Herpes Simplex Virus 2 and/or Trypanosoma cruzi are disclosed.

Abstract: Bombesin is an amphibian peptide that has a structure closely related to that of several mammalian peptides, including Gastrin Releasing Peptide (GRP) and Neuromedins B and C. Bombesin, GRP and related peptides exert their in vivo effects by binding to specific receptors present on cells of the gastrointestinal tract, the central nervous system, and tumors. The invention relates to novel bombesin derivatives which act as bombesin receptor antagonists by blocking the binding of bombesin, GRP or related peptides to cellular receptors. By blocking the binding of bombesin, GRP and related peptides to cellular receptors on cancer cells, these antagonists inhibit the growth of tumor cells that respond to the growth-promoting action of bombesin. These antagonists are expected to block the binding of bombesin, GRP or related peptides to similar receptors on cells in the gastrointestinal tract or the central nervous system.
