The title mol-ecule, C(16)H(16)Br(2)O(8), lies on a crystallographic twofold axis. Weak intra-molecular C-H⋯O hydrogen bonds may, in part, control the conformation of the mol-ecule. In the crystal structure, mol-ecules are connected into a two-dimensional network via weak inter-molecular C-H⋯O hydrogen bonds.
This study aims to observe the effects of doxycycline (DOX) on gap junction remodeling after MI and the susceptibility of rats to cardiac arrhythmia. The proximal left anterior descending coronary artery of rats was ligated to establish a myocardial infarction animal model. DOX, methylprednisolone (MP), or vehicle was intraperitoneally injected into the(More)
In the title compound, C(10)H(13)NO, the N atom and the methyl group are almost coplanar with the benzene ring to which they are bonded [deviations of 0.131 (1) and 0.038 (1) Å, respectively, from the ring plane]. In the crystal structure, inter-molecular C-H⋯O hydrogen bonds form a three-dimensional network. Mol-ecules are stacked parallel to the b-axis(More)
IN THE ZWITTERIONIC TITLE COMPOUND (SYSTEMATIC NAME: 4-{[amino(inimio)methyl]amino}benzenesulfonate), C(7)H(9)N(3)O(3)S, the dihedral angle between the plane of the guanidine grouping and the benzene ring system is 44.87 (7)°. The crystal packing is stabilized by inter-molecular N-H⋯O hydrogen bonds involving all the potential donors.
The asymmetric unit of the title compound, C(14)H(11)NO(2)·0.33H(2)O, contains three 3-hydr-oxy-3-phenyl-isoindolin-1-one (HPIO) mol-ecules and one water mol-ecule. The three independent HPIO mol-ecules differ in the orientations of hydr-oxy and phenyl groups substituted at the 3-position with respect to the planar [r.m.s. deviations of 0.0173, 0.0170 and(More)
In the organic mol-ecule of the title compound, C(19)H(25)O(2)P·0.5H(2)O, the benzene rings are oriented at a dihedral angle of 54.04 (3)°. Intra-molecular C-H⋯O hydrogen bonds result in the formation of two five-membered planar rings, which are oriented with respect to the adjacent benzene rings at dihedral angles of 2.66 (3) and 2.79 (3)°. In the crystal(More)
In the title compound, C(13)H(10)N(2)O(4), the nitro N atom deviates by 0.031 (2) Å from the plane of the benzene ring to which it is attached. The aromatic rings are oriented at a dihedral angle of 50.6 (1)°. An intra-molecular N-H⋯O hydrogen bond occurs. In the crystal, inversion dimers are formed by pairs of O-H⋯O inter-actions.
