4-Hydroxy-5-(2-methoxyphenoxy)-2,2′-bipyrimidin-6(5H)-one dihydrate
The title compound, C15H12N4O4·2H2O, crystallizes with two independent water mol-ecules in the asymmetric unit. The dihedral angles between the mean planes of the benzene and pyrimidine rings and that of the pyrimidin-4-one ring are 85.1 (9) and 82.1 (1)°, respectively. The mean plane of the pyrimidine ring is twisted by 12.8 (8)° from that of the pyrimidin-4-one ring. The dihedral angles betwe...

In the title compound, C15H12N4O4, the dihedral angle between the heterocyclic rings is 12.60 (8)°, and that between the benzene ring and the adjacent heterocyclic ring is 85.14 (6)°. In the crystal, a combination of N-H⋯O and O-H⋯O hydrogen bonds link mol-ecules related by a glide plane into a C(5) C(6)[R (2) 2(9)] chain of rings, which is a distinctly different packing motif to those observed...
متن کاملAntitorsadogenic effects of ({+/-})-N-(2,6-dimethyl-phenyl)-(4[2-hydroxy-3-(2-methoxyphenoxy)propyl]-1-piperazine (ranolazine) in anesthetized rabbits.
Ranolazine [Ranexa; (+/-)-N-(2,6-dimethyl-phenyl)-(4[2-hydroxy-3-(2-methoxyphenoxy)propyl]-1-piperazine] is novel anti-ischemic agent that has been shown to inhibit late I(Na) and I(Kr) and to have antiarrhythmic effects in various preclinical in vitro models. This study was undertaken to investigate the effects of ranolazine on drug-induced Torsade de Pointes (TdP) in vivo. TdP was induced by ...
متن کاملHexaaquamagnesium bis{4-[(5-bromo-2-hydroxybenzylidene)amino]benzenesulfonate} dihydrate
In the title hydrated mol-ecular salt, [Mg(H(2)O)(6)](C(13)H(9)BrNO(4)S)(2)·2H(2)O, the Mg(2+) ion (site symmetry ) adopts a near regular MgO(6) octa-hedral coordination geometry. In the anion, the dihedral angle between the aromatic rings is 2.5 (2)° and an intra-molecular O-H⋯N hydrogen bond generates an S(6) ring. In the crystal, the components are linked by O-H⋯O and O-H⋯Br hydrogen bonds.

ramethylchroman-2-ylmethoxy)benzyl]-2,4-dioxothiazollidine, troglitazone, is a mixture of two racemic diasteromers, the (±)(2R*,5S*) and (±)-(2R*,5R*) diastereomers. The molecular and crystal structures of both diastereomers have been reported.1,2 Slow crystallization of troglitazone with an aqueous acetone solution gave dihydrated single crystals that were different from the reported diastereo...
