the human CB(1) cannabinoid receptor has been evaluated. These compounds are derived from the previously described cannabinoid ligands 5,5'-diphenylimidazolidine-2,4-dione (hydantoins). The replacement of the oxygen by a sulfur leads to an increase of the affinity while the function-i.e., inverse agonism-determined by [(35)S]GTPgammaS experiments remains unaffected. Finally, to evaluate the molecular
合成了一组30个取代的5,5'-二苯基-2-硫代氧杂咪唑啉-4-酮(硫代乙内酰脲)衍生物,并评估了它们对人CB(1)大麻素受体的亲和力。这些化合物衍生自先前描述的大麻素配体5,5'-二苯基咪唑烷-2,4-二酮(乙内酰脲)。用硫取代氧会导致亲和力增加,而[[35] S] GTPgammaS实验所确定的功能(即反向激动作用)仍然不受影响。最后,为了评估可能影响巯基乙内酰脲亲和力的分子参数,对代表性的巯基乙内酰脲和乙内酰脲衍生物进行了分子静电势以及亲脂性计算。总之,5,5'-双-(4-碘苯基)-3-丁基-2-硫代氧杂咪唑啉丁-4-酮(31)和3-烯丙基-5,
