The physiopathology of non-insulin-dependent diabetes mellitus is associated with a dysfunction in the regulation of insulin secretion. The alpha 2-adrenoceptors have been reported to be involved in this alteration, although alpha 2-antagonists containing an imidazoline ring may stimulate insulin secretion independently of alpha 2-adrenoceptor blockage. Recently, a new "imidazoline-binding site...
We have recently identified imidazoline I(1)-receptors in the heart. In the present study, we tested regulation of cardiac I(1)-receptors versus alpha(2) -adrenoceptors in response to hypertension and to chronic exposure to agonist. Spontaneously hypertensive rats (SHR, 12-14 weeks old) received moxonidine (10, 60, and 120 microg/kg/h s.c.) for 1 and 4 weeks. Autoradiographic binding of (125)I-...
The title compound C(12)H(17)N(3)O(2) (+)·Cl(-) consists of a discrete [NITpPyH](+) cation [NITpPy = 2-(4'-pyrid-yl)-4,4,5,5-tetra-methyl-imidazoline-1-oxyl-3-oxide] and a chloride anion. The NITpPy mol-ecule is protonated at the N atom of the pyridyl ring. The anions and cations are connected via N-H⋯Cl hydrogen bonds.
Key words: patellar tendon; bilateral tendon rupture; lems were reported. Her current medications included chronic renal failure; secondary hyperparathyroidism; an angiotensin converting enzyme inhibitor, a long-haemarthrosis acting calcium channel blocker, a centrally acting imidazoline derivative, and famotidine. Ferrous sulfate and subcutaneous recombinant human erythropoietin were given for...
Arginine contains the guanidinium group and thus has structural similarity to ligands of imidazoline and alpha-2 adrenoceptors (alpha-2 AR). Therefore, we investigated the possibility that exogenous arginine may act as a ligand for these receptors in human umbilical vein endothelial cells and activate intracellular nitric oxide (NO) synthesis. Idazoxan, a mixed antagonist of imidazoline and alp...
A series of phenoxy-substituted methylimidazoline derivatives were synthesized and used to define the ligand recognition properties of the imidazoline-binding domain (IBD) on monoamine oxidase (MAO)-B and its role in substrate processing. The rank order of potency for selected compounds in competitive binding studies with the imidazoline [(3)H]idazoxan was different from that in enzyme activity...
In the title compound, guanidinium chloridotrioxidochrom-ate(VI), (CH(6)N(3))[CrClO(3)], both the cation and anion are generated by crystallographic mirror symmetry, with one O and one N atom and the Cr, Cl and C atoms lying on the mirror plane. The bond lengths in the guanidinium cation are inter-mediate between normal C-N and C=N bond lengths, indicating significant delocalization in this spe...
