silico studies suggested that 1 interacts stereoselectively with AMPArs. Single stereoisomers of 1 were prepared in order to evaluate their biological activity. However, studies regarding the configurational stability of the investigated compounds suggested a rapid epimerization at C3 in aqueous solvents, and we can expect the same reaction in vivo. Thus, electrophysiological experiments were performed
能够激活AMPA受体(AMPArs)的化合物的潜在治疗优势导致人们寻求新的AMPAr阳性调节剂。其中,8-氯-2,3,5,6-四氢-3,6-二甲基-吡咯并[1,2,3- de ] -1,2,4-苯并噻二嗪1,1-二氧化物(1)具有由于它是AMPA受体中最活跃的苯并噻二嗪衍生的正调节剂之一,因此引起了特别的注意。它具有两个立体异构中心C3和C6,因此可以作为四个立体异构体存在。在这项工作中,计算机初步研究表明1与AMPAr立体选择性地相互作用。1的单一立体异构体为了评估它们的生物活性而准备了它们。但是,有关所研究化合物的构型稳定性的研究表明,在水性溶剂中,C3处的差向异构迅速发生,我们可以期望在体内发生相同的反应。因此,对两种差向异构混合物(3 *,6 R)-和(3 *,6 S)-8-氯-2,3,5,6-四氢-3,6-二甲基-吡咯烷酮进行了电生理实验。[1,2,3- de ] -1,2,4-苯并噻二嗪1
