  3-[1-(2-Benzoxazolyl)hydrazino]propanenitrile derivatives: inhibitors of immune complex induced inflammation

  摘要：

  3-[1-(2-Benzoxazolyl)hydrazino]propanenitrile derivatives were evaluated in the dermal and pleural reverse passive Arthus reactions in the rat. In the pleural test these compounds were effective in reducing exudate volume and accumulation of white blood cells. This pattern of activity was similar to that of hydrocortisone and different from that of indomethacin. The structural requirements for inhibiting the Arthus reactions were studied by systematic chemical modification of 1. These structure-activity relationship studies revealed that nitrogen 1' of the hydrazino group is essential for activity and must be electron rich, whereas chemical modifications of other sites of 1 had only a modest effect on activity.

  摘要：

  合成了几种对胃肠道蠕动具有兴奋作用的2-哌嗪基苯并噁唑衍生物，并研究了它们对豚鼠回肠收缩的影响。与5-HT3受体激动剂5-羟色胺和邻氯苯基双胍相比，季铵哌嗪基苯并噁唑结构具有受限的构象和立体结构。苯环、氮原子和末端胺的相对位置被认为是形成肠道5-HT3受体激动剂的药效团。在用大鼠进行的阻断血清素诱发反射性心动过缓[Bezold-Jarisch(B-J)反射]的试验中，每个合成化合物的诱发B-J反射的比例是不同的。这些结果表明，在这些5-HT3受体激动剂中，苯并噁唑环的取代基会影响大鼠的诱发B-J反射活性。
