and possesses a higher biological activity with respect to the other one. The S enantiomer was proved to be the eutomer for both IDRA21 and S18986, two of the most studied BTD AMPA positive allosteric modulators. However, recent data highlighted an opposite stereoselectivity for some substituted BTDs (7-chloro-9-(furan-3-yl)-2,3,3a,4-tetrahydro-1H-benzo[e]pyrrolo[2,1-c][1,2,4]thiadiazine 5,5-dioxide
苯并噻二嗪类化合物(BTDs)作为促智剂和神经保护剂具有潜在的治疗活性,因此受到了广泛的关注。充当AMPA阳性变构调节剂的BTD增强了谷氨酸能神经传递,而没有通常与直接激动剂相关的副作用。关于外消旋BTDs进入受体结合袋的结合方式的研究表明,一种对映异构体相对于另一种对映异构体建立了更有利的相互作用并且具有更高的生物学活性。该小号对映异构体被证明是两个IDRA21和S18986中,两个研究最多的BTD AMPA正变构调节的乙酸eutomer。然而,最近的数据强调了某些取代的BTD(7-氯-9-(呋喃-3-基)-2,3,3的立体选择性相反a,4-四氢-1 H-苯并[ e ]吡咯并[2,1- c ] [1,2,4]噻二嗪5,5-二氧化物和7-氯-2,3,4-三甲基-3,4 -dihydro-2 H-苯并[ e ] [1,2,4]噻二嗪1,1-二氧化物)显示出意外的结构-活性关系。在这项工作中,
