In the title compound, [CuCl(2)(C(14)H(12)N(2))], the complex molecule has m symmetry, with the mirror plane oriented parallel to the planar molecule and the ligated Cu(II) atom. The metal centre has a distorted tetra-hedral coordination formed by two N atoms from one 2,9-dimethyl-1,10-phenanthroline ligand and two Cl atoms. There is inter-molecular π-π stacking between adjacent 2,9-dimethyl-1,...

In the structure of the title compound, [Ag(C(2)H(3)O(2))(C(12)H(6)N(2)O(2))]·3H(2)O, the Ag(I) atom is coordinated by both 1,10-phenanthroline-5,6-dione N atoms and one O atom from the acetate anion. The three water mol-ecules are involved in extensive hydrogen bonding to each other and to the acetate O and 1,10-phenanthroline-5,6-dione O atoms. In addition, there are weak C-H⋯O inter-actions.

A new series of pyrrolo[3',4':3,4]pyrrolo[1,2-a]furoquinolines/phenanthrolines and pyrrolo[1,2-a]phenanthrolines were efficiently built up from an 8-hydroxyquinoline derivative or phenanthroline via 1,3-dipolar cycloaddition reaction involving non-stabilized azomethine ylides, generated in situ from the parent furo[3,2-h]quinoliniums/phenanthroliums, in presence of a copper(II) chloride-phenant...

A series of arene Ru(II) complexes coordinated with phenanthroimidazole derivatives, [(η⁶-C₆H₆)Ru(l)Cl]Cl(1b L = p-ClPIP = 2-(4-Chlorophenyl)imidazole[4,5f] 1,10-phenanthroline; 2b L = m-ClPIP = 2-(3-Chlorophenyl)imidazole[4,5f] 1,10-phenanthroline; 3b L = p-NPIP = 2-(4-Nitrophenyl)imidazole[4,5f] 1,10-phenanthroline; 4b L = m-NPIP = 2-(3-Nitrophenyl) imidazole [4,5f] 1,10-phenanthroline) were ...

Cupric phenanthroline was used to catalyze the formation of disulfide bonds in cAMP-dependent protein kinase II. Incubation of holoenzyme alone with cupric phenanthroline resulted in no disulfide bond formation. In contrast, when holoenzyme was preincubated with cAMP prior to treatment with cupric phenanthroline, specific interchain disulfide bonding was found between the regulatory (R) and cat...

Several classes of compounds are able to induce a spectrum of drug-metabolizing enzymes without inducing cytochrome P450s. Examples include antioxidants such as tert-butyl-4-hydroxyanisole and its metabolite tert-butylhydroquinone, dithiolthiones such as oltipraz, and N-heterocycles such as 1,7-phenanthroline. The events associated with induction of UDP-glucuronosyltransferases (UGT), glutathio...

The nuclease activity of 1,10-phenanthroline-copper ion can be targeted to specific DNA sequences by attachment of the ligand to the 5' end of complementary deoxyoligonucleotides via a phosphoramidate linkage. To synthesize the adduct, the phosphorimidazolide of the deoxyoligonucleotide is prepared using a water-soluble carbodiimide and is then coupled to 5-glycylamido-1,10-phenanthroline. Afte...

Investigations into V-agent interaction with 1,10-phenanthroline nitrate Ln(III) complexes (Eu and Tb) were carried out using luminescence and UV-Vis spectroscopy. Addition of several equivalents of agent resulted in the loss of luminescence intensity and the observation of free 1,10-phenanthroline by UV-Vis. We propose a displacement mechanism in which the V-agent acts as a bidentate ligand to...

In the title compound, [Zn(C(5)O(5))(C(12)H(8)N(2))(2)], the Zn atom is in a slightly distorted octa-hedral environment. The mol-ecule lies across a twofold rotation axis, around which two 1,10-phenanthroline ligands are arranged. There are short contacts between the 1,10-phenanthroline groups and the O atoms of the croconate ligand, which probably stabilize the crystal structure via weak C-H⋯O...
