A series of hydroxylated 2-aminotetralins were prepared in the search for irreversible labels for D2 dopamine receptors. N-2-Haloacetyl and N-2-haloalkyl substituents were chosen as potential receptor alkylating groups. Titrimetric studies were carried out on [N-(chloroethyl)-N-methylamino]tetralins 10, 10a, 24, and 26 to demonstrate that aziridinium ions were formed as reactive intermediates from
为了寻找D2多巴胺受体的不可逆标记,制备了一系列羟基化的2-氨基四氢萘。选择N-2-卤代乙酰基和N-2-卤代烷基取代基作为潜在的受体烷基化基团。在[N-(氯乙基)-N-甲基氨基]四氢化萘10、10a,24和26上进行了滴定研究,以证明叠氮鎓离子是由这些化合物形成的反应性中间体。通过对化合物10的1 H NMR研究证实了这一观察结果。所制备的大多数氨基四氢萘蛋白均与垂体前叶D2多巴胺受体表现出相当高的亲和力结合,并表现出激动剂特性。给出了结构活性结果以及旨在鉴定不可逆受体结合剂的初步研究。[N-(2-氯乙基)-N-丙基氨基] -6,
