tested for affinity to nicotinic acetylcholine receptor binding sites in rat brain and for analgesic activity in the mouse hot plate assay. Numerous types of modifications were consistent with high affinity for [3H]cytisine binding sites. By contrast, only selected modifications resulted in retention of analgesic potency in the same range as 1 and 2. Analogs of 2 with one or two methyl substituents at
制备了类似物A-98593(1)及其对映体ABT-594(2),在吡啶环上具有多个取代基,并测试了与大鼠脑中烟碱乙酰胆碱受体结合位点的亲和力以及在小鼠热板测定中的镇痛活性。多种修饰类型与对[3H]胱氨酸结合位点的高亲和力相一致。相比之下,仅选择的修饰导致止痛效果保持在与1和2相同的范围内。还制备了在氮杂环丁烷环的3位带有一个或两个甲基取代基的2的类似物,发现它们的活性实质上较低。两种测定。
