Polycyclic amides 2 and 5-9 were successfully synthesised and their lipophilicity profiles were evaluated using reverse-phase HPLC. All synthesised compounds possessed P2X7R antagonistic properties when tested on rat spinal cord microglia cells. Extensive screening for binding to other neuroreceptor subtypes demonstrated their P2X7 selectivity.

Herein we describe our recent attempts to target the P2X7 receptor for potential treatment of neurological disorders. This work focusses on different polycycles including carborane, adamantane or cubane, joined by either a cyanoguanidine or an amide linker to phenyl or isoquinoline moieties. We have demonstrated the superiority of the adamantyl moiety over other polycycles in terms of synthetic accessibility and biological (cellular) activity. We have also shown that an amide or cyanoguanidine linker can greatly alter the biological activity of compounds. This SAR study provides important insights into the types of functionality required to target the P2X7 receptor. (C) 2017 Elsevier Ltd. All rights reserved.

Relative to other polycyclic frameworks (1-3), a carborane cage (4 and Cs center dot 5) exerts a significant biological effect as an inhibitor of the purinergic P2X(7) receptor (P2X(7)R) which allows one to target depression in vivo and thus demonstrate, for the first time, that a carborane has the capacity to modify CNS activity.[GRAPHICS]

GluN2B subtype-selective NMDA antagonists represent promising therapeutic targets for the symptomatic treatment of multiple CNS pathologies. A series of N-benzyl substituted benzamidines were synthesised and the benzyl ring was further replaced with various polycyclic moieties. Compounds were evaluated for activity at GluN2B containing NMDA receptors where analogues 9, 12, 16 and 18 were the most potent of the series, replacement of the benzyl ring with polycycles resulted in a complete loss of activity.
