چکیده

The title polycyclic alkaloid, C22H26N2O3, an indole derivative obtained from Melodinus yunnanensis, comprises three chiral C atoms and crystallizes as a racemate. Its seven-membered heterocyclic ring has a twisted conformation, with the N atom within the plane of the indole moiety and with two adjacent C atoms deviating in opposite directions from its plane by 0.756 (3) (methyl-ene C) and -0.802 (3) Å (methine C). In the crystal, pairs of N-H⋯O hydrogen bonds connect the mol-ecules into centrosymmetric dimers.

In the title compound, C30H28N2O6, the pyran ring adopts a slightly distorted half-chair conformation and the pyrone ring adopts an envelope conformation, with the C atom bearing the carboxyl-ate group as the flap. The pyrazole ring [maximum deviation = 0.002 (2) Å] forms a dihedral angle of 13.2 (1)° with the attached benzene ring. The near-planar atoms of the pyran ring and the pyrazole ring ...

Comparison of vasodilatory properties of 14,15-EET analogs: structural requirements for dilation.

Epoxyeicosatrienoic acids (EETs) are endothelium-derived eicosanoids that activate potassium channels, hyperpolarize the membrane, and cause relaxation. We tested 19 analogs of 14,15-EET on vascular tone to determine the structural features required for activity. 14,15-EET relaxed bovine coronary arterial rings in a concentration-related manner (ED(50) = 10(-6) M). Changing the carboxyl to an a...

In the title compound, C22H16N2O6, the naphthalene ring systems form a dihedral angle of 65.2 (1)°. Two O atoms of one of the nitro groups are disordered over two sets of sites with occupancy factors of 0.586 (15) and 0.414 (15). Weak C-H⋯O inter-molecular inter-actions are present, forming a ladder like structure along the a axis.

Characterization of 14,15-epoxyeicosatrienoyl-sulfonamides as 14,15-epoxyeicosatrienoic acid agonists: use for studies of metabolism and ligand binding.

Epoxyeicosatrienoic acids (EETs) are cytochrome P450 epoxygenase metabolites of arachidonic acid. EETs mediate numerous biological functions. In coronary arteries, they regulate vascular tone by the activation of smooth muscle large-conductance, calcium-activated potassium (BK(Ca)) channels to cause hyperpolarization and relaxation. We developed a series of 14,15-EET agonists, 14,15-EET-phenyli...

The structure of the title compound, [Cd(3)Cl(6)(C(15)H(15)NO(2))(2)(CH(4)O)(2)](n), is based on a layered zigzag polymeric chain along the c axis. The Cd(II) ions are linked by double chlorine bridges alternating between one CdCl(4)(CH(3)OH)(2) and two CdCl(4)(C(15)H(15)NO(2)) octa-hedral coordination units. Additional intrachain N-H⋯O and O-H⋯Cl hydrogen-bond interactions stabilize this arran...
