Isolated five known iridoids glycosides (Scrophuloside A, Harpagoside B, 5-hydroxyloganin, 8-O-acetylharpagide and 6-O-methyl,1-glucopyranosyl catalpol ),one phenyl ethanoid glycoside (Verbascoside) and a phenyl ethanol amine (2-(4-Chlorobenzyl amino) ethanol ) compound from the methanolic extract of aerial parts of Scrophularia oxysepala using by high performance liquid chromatography based on...

The stabilities of a series of isolated covalent selenium(II) azides such as [2-[1-(3,5-dimethylphenyl)-2-naphthyl]-4,5-dihydro-4,4-dimethyloxazole]selenium azide (2a), [2-(4,4-dimethyl-2-oxazolinyl)phenyl]selenenyl azide (3a), [o-(2,6-diisopropylphenyl-iminomethinyl)phenyl]selenenyl azide (4a), [o-(R)-(methylbenzyliminomethinyl)phenyl]selenenyl azide (5a) and o-formylphenylselenenyl azide (6a)...

The capacities to inhibit coumarin 7-hydroxylase activity of human cytochrome P450 2A6 (CYP2A6) by organosulfur compounds were evaluated. Five dialkyl sulfides and five dialkyl disulfides, with alkyl chains from methyl to amyl, were examined. In addition to these chemicals, diallyl sulfide, diallyl disulfide, allyl methyl sulfide, allyl n-propyl sulfide, allyl phenyl sulfide, diphenyl sulfide, ...

The title compound, C(22)H(18)N(2)O(2), was derived from 1-(2-hydroxy-phen-yl)-3-(4-methoxy-phen-yl)propane-1,3-dione. The central pyrazole ring forms dihedral angles of 16.83 (5), 48.97 (4) and 51.68 (4)°, respectively, with the methoxy-phenyl, phenyl and hydroxy-phenyl rings. The crystal packing is stabilized by O-H⋯N hydrogen bonding.

In the title compound, C30H33BrO6, the pyran-ose ring adopts a chair conformation. Two of the O-benzyl phenyl rings lie almost perpendicular to C/C/C/O plane formed by the ring atoms not attached to these O-benzyl phenyl rings, and form dihedral angles of 85.1 (2) and 64.6 (2)°, while the third O-benzyl phenyl ring is twisted so that it makes a dihedral angle 34.9 (2)° to this C/C/C/O plane. Th...

In the title compound, C(20)H(13)IO(2)S, the O atom and the phenyl group of the phenyl-sulfinyl substituent lie on opposite sides of the plane of the benzofuran fragment; the phenyl ring is almost perpendicular to this plane [83.84 (5)°]. The phenyl ring in the 2-position is rotated out of the benzofuran plane, making a dihedral angle of 40.47 (5)°. The crystal structure is stabilized by non-cl...

In the title mol-ecule, C(22)H(15)NO(3), the configuration about the ethyl-enic double bond is Z configuration and it is approximately coplanar with the adjacent phenyl ring and benzoxazole ring system as indicated by the C(H)=C(O)-C(phen-yl)-C(phen-yl) and O(benzoxazole)-C-C(H)=C(O) torsion angles of 179.88 (15) and 5.7 (2)°, respectively. The dihedral angle between the essentially planar (r.m...

In the title compound, C(23)H(22)N(2)O(2)S(2), the dihedral angles between the 4-meth-oxy-substituted phenyl ring and the other two phenyl rings are 84.4 (4) and 77.7 (1)°, respectively, while the dihedral angle between the two phenyl rings is 57.5 (2)°. The amino group is not involved in an N-H hydrogen bond. The crystal packing is established by inter-molecular C-H⋯O packing inter-actions inv...
