solubilised by four different stereoisomeric dendriticpeptides to form gel-phase materials in toluene was investigated. The second generation dendriticpeptides were based on D- and L-lysine buildingblocks, and each contained three chiral centres. By designing dendriticpeptides in which the configurations of the chiral centres were modified, and applying them as gelator units, the assembly of stereoisomers
Agents and methods for chemoprevention and treatment of neoplasia are described, the agents including a selective inhibitor of inducible nitric oxide synthase and a combination of a selective inhibitor of inducible nitric oxide synthase and an inhibitor of cylcooxygenase-2 in a pharmaceutical composition. The agents and methods are used for chemoprevention and treatment of neoplasia including colorectal cancer and other cancers affecting epithelial cells throughout the body. The agents can also be used to treat the fibrosis that occurs with radiation therapy, as well as adenomatous polyps, including those with familial adenomatous polyposis (FAP).

Amino acids derived diacetylene hydrogelators 1 and 2 which have glycine or alanine moiety as head group were synthesized by several steps. The influences on the hydrogen-bonding interaction between amino acids moieties of hydrogelators in the polymerization by UV irradiation were investigated. The glycine-based hydrogel 1 resulted in the generation of stronger absorption peak at 540 nm at room temperature by UV-irradiation. Interestingly, the red color of the glycine-based diacetylene hydrogel 1 was gradually changed into blue color by decreasing temperature. Finally, the absorption band with 640 nm of glycine-based diacetylene hydrogel 1 showed at 77 K. On the other hand, the alanine-based hydrogel 2 had no significant color change at 77 K. These different color changes between the hydrogels 1 and 2 are attributed to the strong intermolecular hydrogen-bonding interaction between glycine moieties of the hydrogelator 1, as confirmed by FT-IR observation. These results indicate that the hydrogen-bonding strength of the self-assembled hydrogel is a strong influence on the degree of polymerization.
