In the title complex, [CuCl(2)(C(11)H(17)N(4)O(2))(2)], the Cu(II) ion, lying on an inversion center, is six-coordinated in a distorted octa-hedral [Cu(N(2)O(2)Cl(2))] environment by two N,O-bidentate nitronyl nitroxide radical ligands and two trans-chloride anions. In the imidazoline-1-oxyl-3-oxide unit of the ligand, the four methyl groups and the C atoms to which they are bonded are disorder...

Imidazol(in)e compounds show the diversity of pharmacological effects including mydriasis, hypotension, sedation, bradycardia and hypothermia. At first it was postulated that these effects are mediated via α2-adrenoceptors exclusively. Clonidine is well known as a model agent to produce pupillary dilation in rats. However, it became obvious later that clonidine-like imidazol(in)e adrenoceptor a...

Heart Failure To the Editor: We read with great interest the paper by Swedberg et al.1 With respect to it, we will supply additional information that might aid in the understanding of the failure of imidazoline’s agonists to improve chronic congestive heart failure (CCHF) in patients. We have assessed all plasma neurotransmitters in some 30 000 normal and diseased subjects. Included were noradr...

BACKGROUND Moxonidine, a novel imidazoline-alpha2-adrenergic receptor-selective analgesic, was recently identified as antinociceptive but has yet to be evaluated in neuropathic pain models. alpha2-adrenergic receptor-selective analgesics, and high-efficacy opioids, effectively inhibit neuropathic pain behaviors in rodents. In contrast, morphine potency and efficacy decreases in states of neurop...

I. Overview of the computation Reviewing the setup from our lecture notes of last year [S1], we let R denote a crystallographic root system with V the ambient real Euclidean space, along with the usual choices (simple roots, positive roots,...), and W the Weyl group. Given a reduced expression for the longest element of the Weyl group, say w0 = si1 · · · sil , there is an induced ordering β ∨ 1...

In the title compound, C(9)H(9)ClN(2), a substituted imidazoline, the six- and five-membered rings are twisted from each other, making a dihedral angle of 17.07 (5)°. In the crystal structure, a short Cl⋯Cl [3.3540 (3) Å] inter-action is observed. Neighbouring mol-ecules are linked together by inter-molecular N-H⋯N hydrogen bonds into a one-dimensional infinite chain along the [101] direction a...

The inhibition of short-circuit current (Isc) in isolated frog skin and the induction of surface potentials in lipid bilayer membranes produced by the diuretic drug amiloride and a number of its chemical analogues was studied. The major conclusions of our study are: (a) The charged form of amiloride is the biologically active species. (b) Both the magnitude of Isc and the amiloride inhibitory e...
