Three Ruthenium(II) polypyridine complexes, [Ru(phen)2(mipc)]2+(1), [Ru(bpy)2(mipc)]2+ (2) and [Ru(dmb)2(mipc)]2+(3) [mipc = 2-(6-methyl-3-(1H-imidazo[4, 5-f][1,10]-phenanthroline-2-yl)-4H-chromene-4-one, phen = 1,10-phenanthroline,bpy = 2, 2′bipyridine,dmb = 4, 4′-dimethyl-2, 2′-bipyridine] have been synthesized and characterized by elemental analysis, IR,(More)
A new ligand 3-(1H-imidazo[4,5-f][1,10]phenanthrolin-2yl)phenylboronic acid and its (IPPBA) three ruthenium(II) complexes [Ru(phen)2(IPPBA)](ClO4)2 (1), [Ru(bpy)2(IPPBA)](ClO4)2 (2) and [Ru(dmb)2(IPPBA)](ClO4)2 (3) have been synthesized and characterized by elemental analysis, UV/VIS, IR, 1H-NMR,13C-NMR and mass spectra. The binding behaviors of the three(More)
Three new complexes of the type [Ru(phen)2PIP-Cl](1) [Ru(bpy)2PIP-Cl](2) and [Ru(dmp)2PIP-Cl](3) (phen = 1,10-phenanthroline; bpy = 2,2′-bipyridine; dmb = 4,4-dimethyl-2,2′-bipyridine), PIP-Cl = 2-(4′-chloro-phenyl) imidazo[4,5-f][1,10]phenanthroline) were synthesized and characterized by using UV–VIS, IR and 1H-NMR, 13C-NMR spectral methods.

Complexes of β-cylodextrin with five nucleotides of adenine (A), thymine (T) guanine (G), cytosine (C), and 5-methylcytosine have been investigated using Hatree-Fock (HF) and density functional theory (DFT) calculations of different quality. This work was inspired by recent technological advances made in single-molecule sequencing of DNA. One molecule of(More)
Spontaneously arising, H-2Ds-positive SJL/J lymphomas have been reported to become irreversibly more aggressive and H-2Ds-negative upon successive transplantation in syngeneic mice. In an effort to determine whether this process was one of tumor progression, we sought to: (a) establish whether a clonal relationship exists between readily transplantable(More)
