发现精神活性药物的一个主要障碍是无法预测小分子如何改变复杂的行为。我们报道了一种高通量、定量筛选改变斑马鱼幼虫行为的药物的开发和应用。我们发现,观察到的表型的多维性使分子能够根据共同的行为进行分层聚类。行为分析揭示了精神药物分子的保守功能,并预测了特征不明显的化合物的作用机制。此外,行为分析暗示了新的因素,如乙醚-a- a-go-go相关基因(ERG)钾通道和控制休息和运动活动的免疫调节剂。这些结果证明了斑马鱼高通量行为分析在发现和表征精神药物以及剖析复杂行为的药理学方面的力量。
A major obstacle for the discovery of psychoactive drugs is the inability to predict how small molecules will alter complex behaviors. We report the development and application of a high-throughput, quantitative screen for drugs that alter the behavior of larval zebrafish. We found that the multi-dimensional nature of observed phenotypes enabled the hierarchical clustering of molecules according to shared behaviors. Behavioral profiling revealed conserved functions of psychotropic molecules and predicted the mechanisms of action of poorly characterized compounds. In addition, behavioral profiling implicated new factors such as ether-a-go-go-related gene (ERG) potassium channels and immunomodulators in the control of rest and locomotor activity. These results demonstrate the power of high-throughput behavioral profiling in zebrafish to discover and characterize psychotropic drugs and to dissect the pharmacology of complex behaviors.
