The asymmetric unit of the title compound, C18H17N3O2, comprises three independent mol-ecules (1, 2 and 3). In mol-ecule 1, the dihedral angles between the pyrazolone ring and the pendant phenyl and hydroxybenzene rings are 54.43 (6) and 28.72 (6)°, respectively. The corresponding data for mol-ecule 2 are 86.84 (6) and 25.69 (5)°, respectively, and for mol-ecule 3 are 47.41 (7) and 17.09 (7)°, ...

The asymmetric unit of the title compound, C(24)H(21)FN(2)O(5)S, consists of two crystallographically independent mol-ecules. In each mol-ecule, the central dihydro-pyrimidine ring is significantly puckered and adopts a conformation which is best described as an inter-mediate between a boat and a screw boat. The least-squares planes of the dihydro-pyrimidine rings are almost coplanar with the f...

We examined the effects of angiotensin II (Ang II) and Ang-(1-7) on the release of [3H]norepinephrine elicited by nerve stimulation (2 Hz, 0.5 millisecond, for 2 minutes) in rat atria isolated with their cardioaccelerans nerves. The stimulation-induced release of [3H]norepinephrine was increased 50% by 3 x 10(-8) mol/L of either peptide. No further increase in [3H]norepinephrine release was obs...

The title compound, C(16)H(13)NO(3), crystallizes with two independent mol-ecules (A and B) in the asymmetric unit. The dihedral angle between the mean planes of the 4-methyl-phenyl and 3-nitro-phenyl groups is 4.0 (3)° in mol-ecule A and 16.2 (7)° in mol-ecule B. Inter-molecular C-H⋯O hydrogen bonding involving the O atoms of the 3-nitro-phenyl group of both independent mol-ecules link the mol...

The title compound, [Sn(CH(3))(3)(C(6)H(5)O(2)S)](n), forms an infinite chain structure parallel to [100]. There are two mol-ecules of the complex in the asymmetric unit. The geometry of the Sn atoms in both mol-ecules is distorted trigonal-bipyramidal. The S and C atoms of the thio-phene rings in both mol-ecules are disordered over two sites with site-occupancy factors 0.799 (9)/0.201 (9) and ...

The asymmetric unit of the title compound, C(15)H(12)Br(2)N(2)O(2), contains two independent mol-ecules in which the dihedral angles between the benzene rings are 49.5 (7) and 66.4 (7)°. Intra-molecular O-H⋯N hydrogen bonds generate S(6) ring motifs in each mol-ecule. In the crystal, mol-ecules are linked through inter-molecular N-H⋯O hydrogen bonds, forming chains along the b axis.

The asymmetric unit of the title compound, C(15)H(12)I(2)N(2)O(2), contains two independent mol-ecules in which the dihedral angles between the two benzene rings are 62.4 (7) and 41.1 (7)°. Intra-molecular O-H⋯N hydrogen bonds generate S(6) ring motifs in each mol-ecule. In the crystal, mol-ecules are linked through inter-molecular N-H⋯O hydrogen bonds, forming chains along the a axis.
