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。

Constrained nicotine analogues were synthesized and coupled to the carrier protein KLH. The immunogenic effects were compared to those using our previously designed flexible nicotine hapten. Immunization of mice with the constrained hapten conjugates resulted in highly increased antibody titers and affinity for nicotine.

The invention provides an adenovirus-antigen conjugate comprising an adenovirus with a coat protein and an antigen of an addictive drug conjugated to the coat protein of the adenovirus. The invention also provides an adenoviral vector comprising a nucleic acid sequence which encodes an antibody directed against the addictive drug. The invention further provides a method of inducing an immune response against an addictive drug or reducing the effect of an addictive drug in a human by ad-ministering to the human the aforementioned adenovirus-antigen conjugate or antibody encoding adenoviral vector.
