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(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.
In the title compound, C(27)H(23)N(3)O·H(2)O, the benzimidazole ring system has an r.m.s. deviation of 0.0071 Å and makes dihedral angles of 34.51 (2), 55.22 (3) and 41.05 (5)° with the central and N-bonded phenyl rings, respectively. In the crystal, the water mol-ecular is connected to the organic mol-ecule by inter-molecular O-H⋯N hydrogen bonds. Weak(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 title compound, C(16)H(17)ClN(2)O(5), the dihedral angle between the aromatic rings is 77.36 (4)°. An intra-molecular C-H⋯O inter-action results in the formation of a planar [r.m.s. deviation = 0.103 (2) Å] five-membered ring, which is oriented at a dihedral angle of 4.84 (4)° with respect to the adjacent benzene ring. In the crystal structure, weak(More)
