monoamine oxidases A (MAO A) and B (MAO B) determined. Para-substituents with low dipole moment increased the affinity to MAO A, whereas groups with high dipole moment yielded compounds with no or weak affinity. In contrast, the properties affecting MAO B affinity were the polarity and bulk of the para-substituent, with large hydrophobic substituents producing compounds with high MAO B affinity. In addition
已合成了一系列对位取代的4-苯基哌啶/哌嗪,并确定了它们对重组大鼠大脑皮层单胺氧化酶A(MAO A)和B(MAO B)的亲和力。低偶极矩的对位取代基增加了对MAO A的亲和力,而高偶极矩的基团则产生了无亲和力或弱亲和力的化合物。相反,影响MAO B亲和力的特性是对位取代基的极性和体积,其中较大的疏水性取代基会产生具有较高MAO B亲和力的化合物。另外,在自由运动的大鼠中测试了这些化合物,并测量了对验尸后神经化学的影响。在对MAO A而非对MAO B的亲和力与纹状体内3,4-二羟基苯基乙酸(DOPAC)和3-甲氧基酪胺(3-MT)的水平之间显示出线性相关性。
