isoforms. All the synthesized compounds were also tested for their in vivo antiinflammatory activity by two different bioassays namely, carrageenan-induced oedema and acetic acid-induced increase in capillary permeability in mice. In addition, analgesic and ulcerogenic activities were determined. The combined antiinflammatory data from in vivo animal models showed that compound 3k exhibited anti-inflammatory
人口中预期寿命的增加使阿尔茨海默氏病(AD)成为日益严重的公共卫生问题。迫切需要找到预防和延缓疾病的方法。结果表明,单胺氧化酶-B(MAO-B)抑制剂和抗炎药可能有效治疗AD。因此,合成了一系列新型的1-硫代氨基甲酰基-3-取代的苯基-5-(2-吡咯基)-4,5-二氢-(1H)-吡唑衍生物作为有希望的MAO-B抑制剂,并研究了其抑制能力。单胺氧化酶(MAO)的A和B同工型的选择性活性。大多数合成的化合物对MAO-A(化合物3e-3h)和MAO-B(化合物3i-3l)同工型均显示高活性。还通过两种不同的生物测定法测试了所有合成的化合物的体内抗炎活性:角叉菜胶引起的水肿和乙酸引起的小鼠毛细血管通透性增加。此外,还确定了镇痛和促溃疡活性。来自体内动物模型的综合抗炎数据显示,化合物3k具有与消炎痛相当的抗炎活性,且无致溃疡作用。由于化合物3k同时具有抗炎镇痛活性和MAO-B抑制作用,因此需要进一步的详细研究。
