The nAChR has been considered an interesting potential

The α7 nAChR has been considered an interesting potential target for numerous therapeutic indications over the last two decades, with GTS-21 one of the first candidates proposed for Alzheimer's disease [2], [3], [23]. Unfortunately, although many α7-selective agonists have been developed [21], none have made it W 54011 synthesis successfully through clinical trials for cognitive disorders, although small-scale trials continue with GTS-21 and schizophrenia [24]. Appreciation for the potential importance of the cholinergic anti-inflammatory pathway as an avenue for treating diverse indications such as asthma, arthritis, and neuropathic pain has redirected the field to search for different kinds of drugs for these different sorts of diseases, and Linking number paradox may be that attention will shift toward drugs like NS6740 that were once dismissed as an “anti-therapeutic” for cognition.
