Several new 3 beta-(4'-substituted phenyl)-, 3-beta-(3'-substituted phenyl)-, and 3 beta-(3',4'-disubstituted phenyl)tropane-2 beta-carboxylic acid methyl esters were prepared and assayed for inhibition of [3H]WIN 35,428 binding to the dopamine transporter. The 3 beta-(3',4'-dichloro) and 3 beta-(4'-chloro-3'-methyl) analogues (2w and 2y; RTI-111 and RTI-112, respectively) with IC50 values of 0.79
几种新的3β-(4'-取代的苯基)-,3-β-(3'-取代的苯基)-和3β-(3',4'-二取代的苯基)tropane-2β-羧酸甲酯制备并测定对[3H] WIN 35,428与多巴胺转运蛋白结合的抑制作用。3个beta-(3',4'-dichloro)和3个beta-(4'-chloro-3'-methyl)类似物(分别为2w和2y; RTI-111和RTI-112),IC50值为0.79和0.81 nM显示最高亲和力。研究了从经典和比较分子场分析(CoMFA)方法获得的定量构效关系(QSAR)模型对合理药物设计的贡献。CoMFA模型是使用具有SYBYL默认值的空间和静电势导出的,而经典模型是根据pi和MR参数导出的。使用12个化合物的训练集,两个模型都用于预测训练集内外的化合物的结合亲和力。CoMFA研究为影响与DA转运蛋白结合的空间和静电因素提供了新的见解,并为我们最初的发现提供了额
