Geranyl Derivatives of Isoquinoline Alkaloids Show Increased Biological Activities
摘要:
Three types of isoquinoline alkaloids were tested for antimicrobial, cytotoxic, anti-malarial, anti-oxidant, and anti-HIV activities, as well as inhibitory activity against Epstein-Barr virus early antigen (EBV-EA) activation induced by 12-O-tetradecanoylphorbol-13-acetate (TPA) in Raji cells. N- or O-Geranylation contributed to increased potency in four types of activities except anti-HIV and anti-oxidant. Some types of alkaloids may be useful as lead compounds for developing potential chemotherapeutic agents. N,N-Geranylated salsolinol was significantly active in three different assays, antimicrobial, cytotoxic, and EBV-EA, and may be a most useful compound.
The invention relates to an image support medium for creation of an aesthetic image that is an work or object for display. This support medium includes a polymer in an amount sufficient to enable the image to have at least one aesthetic element. In different embodiments, the image support medium is an image support stabilizer, the polymer is a synthetic absorbent or conductive polymer, or the polymer is a transparent or synthetic translucent polymer and a property of this transparent or translucent polymer is enhanced to facilitate the creation or preservation of the image by at least one stabilizer. The invention also relates to a method for preparing this image support medium. The method includes forming a reaction mixture comprising a monomer in an amount sufficient to provide or enable the image to have an aesthetic element, and processing the reaction mixture into a 2- or 3-dimensional shape.
