  5-Arylbenzothiadiazine Type Compounds as Positive Allosteric Modulators of AMPA/Kainate Receptors

  摘要：

  The potential therapeutic benefit of compounds able to activate AMPA receptors (AMPAr) has led to the search for new AMPAr positive modulators. On the basis of crystallographic data of the benzothiadiazines binding mode in the S1S2 GluA2 dimer interface, a set of 5-aryl-2,3-dihydrobenzothiadiazine type compounds has been synthesized and tested. Electrophysiological results suggested that 5-heteroaryl substituents on the benzothiadiazine core like 3-furanyl and 3-thiophenyl dramatically enhance the activity as positive modulators of AMPAr with respect to IDRA21 and cyclothiazide. Mouse brain microdialysis studies have suggested that 7-chloro-5-(3-furyl)-3-methyl-3,4-dihydro-2H-1,2,4-benzothiadiazine 1,1-dioxide crosses the blood-brain barrier after intraperitoneal injection. Biological results have been rationalized by a computational docking simulation that it has currently employed to design new AMPAr-positive modulator candidates.

  A compound of formula I is described: which showed to be surprisingly and significantly effective as an allosteric modulator of the AMPA receptor and is therefore particularly suitable for the treatment of mnemocognitive disorders ascribable to an alteration of glutamatergic neurotransmission, such as age-related disorders, anxiety, progressive neurodegenerative disorders, depressive disorders, schizophrenia, obsessive-compulsive disorders and bipolar disorder.

  描述了一种化学式为I的化合物：它被发现是一种令人惊讶且显著有效的AMPA受体异构调节剂，因此特别适用于治疗由谷氨酸能神经递质传递失调引起的记忆认知障碍，如与年龄相关的障碍、焦虑症、进行性神经退行性疾病、抑郁症、精神分裂症、强迫症和躁狂症。
