IDRA-21是种AMPA受体（英语：AMPA receptor）的正別構調節劑（英语：Allosteric modulator），也是苯丙噻二嗪（英语：Benzothiadiazine）的衍生物，也是一种手性分子，(+)-IDRA-21是其活性形式。[1]

在动物实验中，IDRA-21表现出了有促进学习的效果，并能明显改善学习和记忆。在逆转阿普唑仑或东莨菪碱诱发的认知障碍方面，有着约比茴拉西坦（英语：Aniracetam）10到30倍的效力，[2][3]且在单次服用后，可产生长达48小时的持续效应，[4]其作用机制，被认为是通过促进大脑突触间的诱导LTP达到的。[5]

正常情况下，IDRA-21或许不产生神经毒性，[6]但可能会加重中风或癫痫发作后，因全身缺血所造成的神经元损伤。[7]

与安帕金（英语：Ampakine）或苯甲酰哌啶衍生的AMPA受体增效剂相比，IDRA-21药效优于CX-516（英语：CX-516），低于CX-546（英语：CX-546）。[8]与IDRA-21相比，效力更好的苯丙噻二嗪（英语：Benzothiadiazine）类衍生物已被开发出来，[9][10]但这些衍生物，各所获的研究程度并不一样，苯甲酰基哌啶（benzoylpiperidine）和苯甲酰基吡咯烷CX系列（benzoylpyrrolidine CX-series）药物，在临床开发中更受青睐，这或是由于它们在高剂量使用时，具有更有利的毒性特征。[11]
