3,4-Diaminopyridinium 2-carboxy-4,6-dinitrophenolate
In the title salt, C(5)H(8)N(3) (+)·C(7)H(3)N(2)O(7) (-), the pyridine N atom of the 3,4-diamino-pyridine mol-ecule is protonated. The 3,5-dinitro-salicylate anion shows whole-mol-ecule disorder over two orientations with a refined occupancy ratio of 0.875 (4): 0.125 (4). In the crystal, the cations and anions are connected by inter-molecular N-H⋯O and C-H⋯O hydrogen bonds, forming a three-dime...
متن کاملCrystal structure of 8-hydroxyquinolinium 2-carboxy-6-nitrobenzoate monohydrate
In the title hydrated salt, C9H8NO(+)·C8H4NO6 (-)·H2O, the deprotonated carboxyl-ate group is almost normal to its attached benzene ring [dihedral angle = 83.56 (8)°], whereas the protonated carboxyl-ate group is close to parallel [dihedral angle = 24.56 (9)°]. In the crystal, the components are linked by N-H⋯O and O-H⋯O hydrogen bonds, generating [001] chains. The packing is consolidated by C-...
متن کاملCrystal structure of quinolinium 2-carboxy-6-nitrobenzoate monohydrate
In the anion of the title hydrated mol-ecular salt, C9H8N(+)·C8H4NO6 (-)·H2O, the protonated carboxyl and nitro groups makes dihedral angles of 27.56 (5) and 6.86 (8)°, respectively, with the attached benzene ring, whereas the deprotonated carb-oxy group is almost orthogonal to it with a dihedral angle of 80.21 (1)°. In the crystal, the components are linked by O-H⋯O and N-H⋯O hydrogen bonds, g...
متن کاملBiological effects of 5-carboxy-2'-deoxyuridine: hydrolysis product of 5-trifluoromethyl-2'-deoxyuridine.
5-Carboxy-2'-deoxyuridine (5-COOH-2'-dUrd) is a product of the base-catalyzed hydrolysis of 5-trifluoromethyl-2'-deoxyuridine. Hydrolysis of 5-trifluoromethyl-2'-deoxyuridine to 5-COOH-2'-dUrd in phosphate-buffered saline was kinetically first order and was pH dependent. At 37 degrees C and pH 7.0, 7.5, and 8.0, hydrolysis occurred with rate constants of 4.19 x 10(-5), 9.30 x 10(-5), and 1.61 x...
متن کامل(1S)-1-Phenylethanaminium 4-{[(1S,2S)-1-hydroxy-2,3-dihydro-1H,1'H-[2,2'-biinden]-2-yl]methyl}benzoate.
The title molecular salt, C(8)H(12)N(+)·C(26)H(21)O(3)(-), contains a dimeric indane pharmacophore that demonstrates potent anti-inflammatory activity. The indane group of the anion exhibits some disorder about the α-C atom, which appears common to many structures containing this group. A model to account for the slight disorder was attempted, but this was deemed unsuccessful because applying b...
