The pyridine analogs of 5-hydroxy-2-(di-n-propylamino)tetralin (5-OH-DPAT), 4-6, were synthesized, and their biological activity was compared to that of 5-OH-DPAT. Compounds 4 and 6 exhibited activity similar to 5-OH-DPAT in dopamine (DA) D2 and D3 receptor binding and in autoreceptor activation as measured by their ability to reverse the gamma-butyrolactone-induced increase in rat DA synthesis. Behaviorally
合成了5-羟基-2-(二正丙基氨基)四氢化萘的吡啶类似物(5-OH-DPAT)4-6,并将它们的生物活性与5-OH-DPAT进行了比较。化合物4和6在多巴胺(DA)D2和D3受体结合以及在自体受体激活中表现出与5-OH-DPAT相似的活性,通过它们逆转由γ-丁内酯诱导的大鼠DA合成增加的能力来衡量。从行为上讲,低剂量时4和6降低大鼠(sc)的运动能力(LMA),但高剂量时LMA的增加幅度不及5-OH-DPAT,这表明4和6对DA的选择性更高。自体受体。尽管有4只大鼠的口服活性较低,但6只似乎保留了其大部分行为潜能。类似物5在体内或体外显示几乎没有活性。
