In this paper we report the design, synthesis and pharmacological evaluation of new N-substituted 2-amino-1,4-dihydroquinazolines, 2-amino-1,4-dihydropyridopyrimidines and 2-amino-4,5-dihydro-1,3-benzodiazepines as α2-adrenoceptors ligands. Computational studies show that the proposed substitutions and guanidine-containing ring size will probe an extensive area of the active site. Preparation of these molecules involved novel routes than those previously utilised in our laboratory for the preparation of the acyclic aryl-guanidine counterparts. Compounds 8b and 18c showed the highest affinity and antagonistic activity, within their series, towards the α2-adrenoceptor in human brain tissue in?vitro experiments. Structure-activity relationships have been established for the design and biological evaluation of novel α2-adrenoceptor ligands.

A series of novel arylpyrid-3-ylmethanones (7a-aa) were designed as modulators of α7 nicotinic acetylcholine receptors (nAChRs). The methanones were found to be type I positive allosteric modulators (PAMs) of human α7 nAChRs expressed in Xenopus ooctyes. Structure-activity relationship (SAR) studies resulted in the identification of compound 7v as a potent and efficacious type I PAM with maximum modulation of a nicotine EC 5 response of 1200% and EC50 = 0.18 μM. Compound 7z was active in reversing the effect of scopolamine in the novel object recognition (NOR) paradigm with a minimum effective ip dose of 1.0 mg/kg (2.7 μmol/kg). This effect was blocked by the selective α7 nAChR antagonist methyllycaconitine (MLA). These compounds are potent type I positive allosteric modulators of α7 nAChRs that may have therapeutic value in restoring impaired sensory gating and cognitive deficits in schizophrenia and Alzheimer's disease.
