the nitrogen atom is replaced with a neutral methyl sulfide, a neutral methyl selenide, a charged dimethylsulfonium iodide, and a charged dimethylselenonium iodide. These analogues were tested for their ability to inhibit the K+-stimulated release of [3H]acetylcholine from striatal slices. At 30 microM concentration, the charged sulfonium and selenonium salts possessed significant agonist activity while
在生理pH值下,多巴胺可以不带电荷的胺或带电荷的铵盐形式存在。为了了解哪些物种更适合与多巴胺受体相互作用,我们合成了多巴胺类似物,其中的氮原子被中性甲基硫化物,中性甲基硒化物,带电的二甲基碘化碘和二甲基硒化碘化物。测试了这些类似物抑制由K +刺激的纹状体切片中[3H]乙酰胆碱释放的能力。在浓度为30 microM时,带电荷的sulf盐和硒盐具有显着的激动剂活性,而相应的中性物质则没有活性,这表明带电荷的物质最适合多巴胺激动剂活性。此外,将甲基硫转化为相应的亚砜和砜。然而,这些氧化产物均不具有作为多巴胺能激动剂的显着活性。
