A series of phenyl-substituted pyrones, pyridines, and pyrimidines bearing a 5-tetrazolyl or N-(5-tetrazolyl) carbamoyl group as an acidic moiety was synthesized. The compounds were tested for antiallergic activity by passive cutaneous anaphylaxis (PCA) assay in rats after oral administration. Among the compounds synthesized. N-(5-tetrazolyl)-6-phenylpyridine-2-carboxamides (53, 54 and 55) were found to display remarkably high potency.
合成了一系列以 5-四唑基或 N-(5-四唑基)氨基甲酰基为酸性分子的苯基取代的吡喃、吡啶和嘧啶。这些化合物在大鼠口服后通过被动皮肤过敏试验(PCA)测试其抗过敏活性。合成的化合物包括发现 N-(5-四唑基)-6-苯基吡啶-2-甲酰胺(53、54 和 55)具有显著的高效力。
