The present invention provides hapten derivatives that are useful for the preparation of antigens, antibodies and reagents having superior performance characteristics for use in immunoassays for the detection of LSD and nor-LSD. In the present invention the LSD nucleus is derivatized out of the indole nitrogen to form an aminoalkyl derivative. Derivatives have also been synthesized out of the piperidine nitrogen of the LSD nucleus. The resulting haptens can then be further modified at these functionalized positions for linking to appropriate antigenic or labelling groups to provide reagents for LSD immunoassays having excellent sensitivity and selectivity for both LSD and nor-LSD.
本发明提供了一种可用于制备抗原、抗体和试剂的半抗原衍生物,这些试剂在用于检测LSD和去甲-LSD的免疫分析中具有优良的性能特征。在本发明中,LSD核心通过吲哚氮原子衍生化形成氨基烷基衍生物。还从LSD核心的哌啶氮原子合成了衍生物。然后可以在这些功能化位置进一步修饰得到的半抗原,以便与适当的抗原或标记基团连接,为LSD免疫分析提供具有对LSD和去甲-LSD都具有极佳灵敏性和选择性的试剂。
