Title compound, 8, has been synthesized from isoquinolinone, 1 (an improved preparation for which is presented) and separated into its antipodes with D- and L-di-p-toluoyltartaric acids. These antipodes and the racemic precursor have been evaluated (and found active) in two in vivo systems for their effects. The most potent of the three, (+)-8, has an ED50 of 7.13 mumol/kg for inhibition of spontaneous
标题化合物8是由异喹啉酮1(提出的一种改良制剂)合成的,并与D-和L-di-p-甲苯基酒石酸分离成对映体。这些对映体和外消旋体前体已经在两个体内系统中进行了评估(发现具有活性),以证明它们的作用。三种中最有效的(+)-8抑制自发活性的ED50为7.13μmol/ kg,抗伤害感受的ED50为7.45μmol/ kg,而(S)-(分别为4.44和4.81μmol/ kg -)-尼古丁。化合物(-)-8和7的效力约为四分之一。异构体(+)-8具有3aR,9bS构型,后者对应于通过X射线晶体学测定的(S)-(-)-烟碱。但是,(+)-8无法竞争[3H]-烟碱结合,其药理作用并未被美卡明胺阻断。
