Breast cancer stem cells (CSCs) are a sub-population of tumour that can promote breast relapse and metastasis. Current treatments unable to completely remove CSCs, therefore it is essential develop new chemotherapeutics CSCs at clinically compatible doses. Here we present the synthesis, characterisation, anti-breast CSC properties copper(II) complexes, [Cu(L2)(1,10-phenanthroline)]PF6 (2) [Cu(L...

Coordination of Zn(2+) to a ditopic phenanthroline-macrocycle receptor takes place in three steps, the first one being the coordination to the phenanthroline, followed by the slow movement of the metal to the polyamine macrocycle and a final re-arrangement to coordinate the pendent arm.

The synthesis, characterization, electrochemical and photophysical properties of three novel polypyridine rhenium(I) complexes coordinated to an organoselenide ligand, 4-(phenylseleno)-pyridine (PhSepy), structurally related ligands, fac-[Re(CO)3(NN)(PhSepy)]+ NN = 1,10-phenanthroline (phen), 4,7-diphenyl-1,10-phenanthroline (ph2phen) pyrazino[2,3-f]-1,10-phenanthroline (dpq), are reported. In ...

A new selective medium (PC agar) for the isolation of Pseudomonas aeruginosa was developed, consisting of 30 micrograms of 9-chloro-9-[4-(diethylamino)phenyl]-9,10-dihydro-10-phenylacridine hydrochloride (C-390) per ml and 30 micrograms of phenanthroline per ml in Columbia agar. PC agar was superior to phenanthroline, C-390, acetamide, and cetrimide agars for the selective growth of P. aeruginosa.

A concise synthetic protocol for aryl functionalized phenanthrolines has been developed. It was demonstrated that 3,8-diphenyl-1,10-phenanthroline (7a) is competent in promoting transition-metal-free direct arylation and 2,3,8,9-tetraphenyl-1,10-phenanthroline (8a) is a highly efficient ligand in the in situ Pd-catalysed Heck reaction.

Two Anderson-type heteropolyanion-supported copper phenanthroline redox couples have been successfully introduced into dye-sensitized solar cells, which can significantly increase the short-circuit photocurrent, open-circuit voltage and the conversion efficiency by 2.2 times, 26.8% and 3.93 times respectively, compared to the pristine copper phenanthroline redox couple.

Condensation of 5,6-diamino-4,7-phenanthroline with glyoxal provides 1,4,5,12-tetraazatriphenylene in quantitative yield. This procedure avoids the 50% loss of product inherent in previous methods. Derivatives were also prepared by using alpha-dicarbonyl compounds other than glyoxal. Additional derivatives were prepared from 1,4,5,12-tetraazatriphenylene-2,3-dicarbonitrile, produced by condensa...

New ytterbium (III) compounds with β-diketones (2,7-dimethyl-octene-1-dione-3,5 and 2,6-dimethylheptene-1-dione-3,5) their derivatives phenanthroline have been synthesized. The composition chemical structure of the obtained complexes determined by several Phy­sico-chemical investigations. It has shown, that Yb ion coordinates three ligand molecules coordination sphere is supplemented two mole­c...

New fused pyrrolo-phenanthroline type derivatives were synthesized, in two steps, from 1,10-phenanthroline and evaluated for antimicrobial activity fluorescence properties. Our synthetic approach involved a 3+2 dipolarcycloaddition of some selected N-substituted 1,10-phenanthrolin-1-ium ylides, (m)ethoxycarbonyl cyano (1,2-di)substituted acetylenes alkenes, respectively. The structures compound...
