  制备并测试了各种N-芳基-N'-苯基硫脲、N,N'-二芳基硫脲和N-(1,2,4-三唑-3-基)-N'-芳基硫脲的解偶联活性。结果表明，对于解偶联活性而言，二芳基硫脲的苯基4-位取代非常重要。含有两个或更多卤素原子的二苯基硫脲表现出强烈的活性。在两个苯基上都含有硝基的化合物显示出最高的活性。这些结果表明，化合物对疏水性和酸性对于解偶联活性具有首要重要性。当硫脲被吡啶和1,2,4-三唑环取代时，活性显著下降。还研究了苯基异硫氰酸酯与3-氨基-1,2,4-三唑的反应。

  Synthesis and Pharmacological Activity of Triazole Derivatives Inhibiting Eosinophilia

  摘要：

  In order to develop novel antiasthmatic agents based on a new mechanism of action, a series of 3-substituted 5-amino-1-[(methylamino)(thiocarbonyl)]-1H-1,2,4-triazole derivatives were synthesized and evaluated in a model in which eosinophilia was induced in the ah-way through intravenous (iv) injection of Sephadex particles on days 0, 2, and 5. After screening of several hundred derivatives, we finally identified the highly potent eosinophilia inhibitor 5-amino-3-(4-chlorophenyl)-1-[(methylamino)(thiocarbonyl)]-1H-triazole (23c, GCC-AP0341), which had ID50 values of 0.3 and 0.07 mg/kg when administered orally (os) and intraperitoneally tip), respectively. This compound showed complete inhibition of the hypersensitivity induced by ascaris inhalation at an ip dose of 1 mg/kg as well as low toxicity, with an LD(50) value of > 2.0 g/kg in mice. Extensive study of its mechanism of action revealed that 23c inhibited eosinophil survival induced by interleukin-5 (IL-5), but had little or no effect on leukotriene D-4 (LTD(4)) or platelet-activating factor (PAF)-induced responses. Taken together, these results suggest 23e as a novel candidate for the treatment of chronic asthma. Further studies are now underway.

  Various N-aryl-N'-phenylthioureas, N, N'-diarylthioureas and N-(1, 2, 4-triazol-3-yl)-N'-arylthioureas were prepared and examined for uncoupling activities. The results indicate that substitution at the 4-position of the phenyl groups of diaryl thioureas is very important for uncoupling activities. Diphenyl thioureas substituted with two or more halogen atoms exhibited strong activities. The highest activity was exhibited by a compound containing nitro groups on both phenyl groups. These results indicate that the hydrophobicity and acidic nature of the compound are of primary importance for uncoupling activities. A remarkable decrease in activity was observed with the thioureas which were substituted with pyridine and 1, 2, 4-triazole rings. The reaction of phenyl isothiocyanate with 3-amino-1, 2, 4-triazole was also studied.
