hallucinogenic drugs whose detection in body fluids could be simplified by immunochemical assay kits. Antibodies for these assays are obtained by the immunization of laboratory animals with conjugates of a hapten similar to the target analyte and a suitable protein. Therefore we synthesized novel haptens derived from tryptamine-based drugs, with N,N-dimethyltryptamine (DMT), 5-methoxy-N,N-dimethyltryptamine
色胺是一组致幻药物,可以通过免疫化学检测试剂盒简化其在体液中的检测。用于这些测定的抗体是通过使用与目标分析物类似的半抗原和合适的蛋白质的缀合物对实验动物进行免疫而获得的。因此,我们合成了基于色胺的药物衍生的新型半抗原,选择N , N-二甲基色胺(DMT)、5-甲氧基-N , N-二甲基色胺(5-MeO-DMT)和N , N-二异丙基色胺(DiPT)作为半抗原。目标分析物。它们的结构用以羧基结尾的短连接体进行修饰。将半抗原与牛血清白蛋白(BSA)缀合,并用缀合物免疫兔子。获得的多克隆抗体表现出良好的反应性,构建的ELISA的LOD在0.006–0.254 ng mL -1范围内。因此,它们适合开发免疫化学测定试剂盒。
