A new family of imidazoline-arylene macrocycles have been constructed through the simultaneous formation of four imidazoline rings in one step. These macrocycles can efficiently complex with fullerenes C60 and C70 through the formation of ground-state complexes.

Non-adrenergic ligands that bind to imidazoline receptors (I-R), a selective ligand that binds to alpha2-adrenoceptors (alpha2-AR) and mixed ligands that bind to both receptors were tested for their action on water intake behavior of 24-h water-deprived rats. All drugs were injected into the third cerebral ventricle. Except for agmatine (80 nmol), mixed ligands binding to I-R/alpha2-AR such as ...

Integrated experimental and computational studies reveal a new mechanism for Fe-catalyzed imidazoline synthesis through combined nitrene transfer acetonitrile attack of styrenyl radical intermediate.

Compounds with an imidazoline or guanidinium moiety elicit a variety of stimulatory and inhibitory cell responses in both central and peripheral tissues. Many of these effects are mediated by interaction with alpha-adrenergic receptors, but these molecules also selectively recognize other membrane-bound proteins with high affinity. We used a functionalized derivative of the imidazoline molecule...

in this study using clonidine (a mixed ?2 /i1 receptors agonist), tizanidine (pure ?2-receptor agonist), rilmenidine (i1 receptor agonist) and yohimbine (?2-receptor antagonist), we tried to clarify the role of imidazoline and ?2-receptors in morphine withdrawal syndrome. morphine-dependence was induced by administration of increasing doses of morphine in mice. after the last administration of ...
