Description IDRA-21 is a positive AMPA receptor modulator.
In vivo 口服IDRA 21能显著提高年轻成年恒河猴在延迟匹配样本(DMTS)任务中的表现。在0.15-10 mg/kg剂量范围内,改善的模式持续到单剂量给药后的48小时。在给予IDRA 21的最佳剂量后,对于长时间延迟(最困难)的试验,任务准确率比对照组提高了34%。为了确定这一积极的记忆反应是否可以保持,动物们随机分配了固定剂量的IDRA 21。重复剂量间隔3天,以便考虑潜在的累积效应。IDRA 21导致任务准确性逐渐提高,在三周的间歇给药计划期间,平均保持在对照组表现水平以上。单独一组年龄超过20岁的老年猴在对照测试期间的DMTS表现效率方面受损,与年轻队列相比。IDRA 21也提高了老年恒河猴在相同剂量范围内的任务准确性,但反应没有年轻动物那样强烈。老年受试者对药物剂量的个体敏感性也更高,他们的任务潜伏期比年轻组短[1]。
