上下文语境如下：
Before the introduction of high-throughput screening (HTS) and combinatorial screening libraries, most screening for new CNS drugs was performed using biochemical methods, followed quickly by descriptive animal studies that could indicate whether or not a compound penetrated the BBB. A lead compound would then be profiled against receptor panels to look for selectivity. For instance, a synthetic derivative ABT-594, a very potent nonopiate analgesic, derived from the Central American tree frog compound epibatidine,5was profiled against more than 70 receptors and ion channels before clinical investigation. 返回小木虫查看更多
