The adrenergic receptors or adrenoceptors are a family of G-protein coupled receptors split into α and β subclasses. The adrenoceptors have important roles in regulating a myriad of physiological conditions and their malfunction has been implicated in the pathophysiology of a number of diseases. Disclosed herein are a series of novel guanidine and 2-aminoimidazoline compounds which are ligands of the alpha2-adrenoceptor (α2-ARs) subclass of adrenergic receptors. The invention also provides for pharmaceutical compositions comprising the novel compounds. The compounds are suitable for use in the manufacture of medicaments for the treatment of α2-ARs associated disorders, such as depression, schizophrenia, glaucoma and analgesia.

The preparation of a number of (bis)ouanidine and (bis)2-aminoimidazoline derivatives as potential alpha(2)-adrenoceptor antagonists for the treatment of depression is presented. Human brain tissue was used to measure their affinity toward the alpha(2)-adrenoceptors in vitro. Compounds 6b, 8b, 9b, 10b, 15b, 17b, 18b, 20b, and 21b displayed a good affinity (pK(i) > 7) and were evaluated in in vitro functional [(35)S]GTP gamma S binding assays in human prefrontal cortex to determine their agonistic or antagonistic activity. Among these compounds, 17b and 20b showed the expected behavior for an antagonist and were subject to in vivo microdialysis experiments in rats. Significantly, these experiments confirmed the antagonistic properties of 17b and 20b, and therefore both compounds can be considered as potential antidepressants.

Benzamidine and benzguanidine functionality have been found to increase both antibacterial and adjuvant activity of small molecules against Gram-negative pathogens. Herein, we examine the antibacterial activity of a series of dimeric small molecules with benzamidine, benzguanidine, dimethyl amine, and pyridine moieties against multidrug resistant Pseudomonas aeruginosa.
