This activity is comparable to stilbamidine, hydroxystilbamidine, and pentamidine in this test. In contrast, 2,5-bis(4-guanylphenyl)-1,3,4-oxadiazole shows a sharp reduction in activity in our test system. Generally, the cyclic guanyl analogues exhibit low orders of activity, and toxicity begins to appear at moderate dosage levels. All guanyl and cyclic guanyl compounds were synthesized from bisnitrile
2,5-双(4-胍基苯基)-1,3-恶唑,2,5-双(4-胍基苯基)-1,3,4-恶二唑和-1,3,4-噻二唑和3,6-已经合成了双(4-胍基苯基)哒嗪及其一些“环状胍基”类似物。2,5-双(4-胍基苯基)-1,3-恶唑和-1,3,4-噻二唑对小鼠的罗氏锥虫表现出良好的活性,没有急性毒性,以3 mg / kg的剂量水平可以治愈。在该测试中,该活性与stilbamidine,hydroxystilbamidine和pentamidine相当。相反,在我们的测试系统中,2,5-双(4-胍基苯基)-1,3,4-恶二唑的活性急剧下降。通常,环状鸟苷类似物表现出低级活性,并且在中等剂量水平下开始出现毒性。
