  摘要：

  A series of mono-glycoloylamino derivatives was synthesized by treatment of the corresponding aromatic monoamine derivatives with glycoloyl chloride derivatives in pyridine or dichloromethane, in the presence of a base such as triethylamine or pyridine. Hydrolysis of acetoxy compounds in aqueous ammonia and methanol solution produced hydroxy derivatives with ease. These compounds were tested in the rat PCA (passive cutaneous anaphylaxis) assay by oral administration. Thiazole and thiadiazole derivatives showed moderate inhibition in this assay. In contrast, benzothiazole and benzonitrile derivatives exhibited marked inhibition. In particular, compound 5t also showed marked inhibition of eosinophil adhesion to TNF (tumor necrosis factor) -alpha-treated HUVEC (human umbilical vein endothelial cells) in the range of 10(-8)-10(-5) M.
