  Cyclic and branched acyl chain galactoglycerolipids and their effect on anti-tumor-promoting activity

  摘要：

  Fifteen new galactoglycerolipid analogues, in which one or two branched, alicyclic or aromatic acyl chains are linked to 2-O-beta-D-galacto-sylglycerol (6'-position or 1,6' positions), were prepared and tested for their anti-tumor-promoting activity using a short-term in vitro assay for Epstein-Barr virus early antigen (EBV-EA) activation. All compounds were active in inhibiting the EBV activation promoted by the tumor promoter 12-O-tetradecanoylphorbol-13-acetate (TPA), the branched compounds resulting in the most active glycoglycerolipid analogues of the series. The branched 2-O-[6-O-(3-methylbutanoyl)-beta-D-galactopyranosyll-sn-glyceroI (1a) and the structurally related alicyclic 2-O-[6-O-(2-cyclohexylethanoyl)-beta-D-galactopyranosyl]-sn-glycerol (1d), when tested in an in vivo two-stage carcinogenesis test, exhibited inhibitory effects on mouse skin tumor promotion.

  A medical resin composition is produced by mixing a powder of a polymer (A) comprising repeating units having an ester group and a liquid of a vinyl ester monomer (B) having 6 or more carbon atoms to increase a viscosity and, according to demand, further performing a polymerization reaction. The thus produced resin composition inhibits leaching of irritative substances, reduces any adverse effects on the human body by endocrine disruptors, etc. and can be prepared with high operational efficiency. The resin composition is suitably used as a dental resin composition such as a tissue conditioner, a functional impression material, a lining material, a denture base material or a mouth piece material.
