Determination of isoquinoline alkaloids in Thalictrum herbal drugs by non-aqueous capillary electrophoresis

A rapid non-aqueous capillary electrophoresis method has been developed for the separation and determination, within 14 min, of eight isoquinoline alkaloids (berberine, palmatine, jatrorrhizine, (+)-tetrandrine, berbamine, thalifaricine, northalfine, and thalistine) in seventeen samples of the herbal drug thalictrum. A methanolic solution of sodium acetate (75 mm) and acetic acid (1 M) was found to be the optimum running buffer for the separation. Thalictrum Atriplex Finet et Gagep (T. AFG) was selected for further study, including investigation of recovery and precision, because this preparation contained all the isoquinoline alkaloids tested. Calibration curves were highly linear over a 20-fold concentration range and detection limits for all eight alkaloids were in the range 0.42-3.04 mug mL(-1).

Platinum(II) and copper(I) 1-(2-diphenylphosphino-1-naphthyl) isoquinoline complexes: Synthesis and phosphorescence at ambient conditions

The compounds Pt(quinap)(CN)(2), Cu(quinap)(2)(+) and [Cu(quinap)I](2) with quinap = 1-(2-diphenylphosphino-1- naphthyl) isoquinoline were synthesized. Quinap is a bidentate ligand which contains a isoquinoline and an arylphosphine group with CT acceptor properties. Accordingly, the Pt(II) and Cu(I) quinap complexes are characterized by a phosphorescence originating from the lowest-energy MLCT triplets with some IL admixture. (c) 2008 Elsevier B.V.

Tetra-mu(2)-acetato-kappa O-8:O ‘-bis[(isoquinoline-kappa N)copper(II)]

In the crystal structure of the title compound, [Cu-2(CH3-COO)(4)(C9H7N)(2)], the Cu-II cation is coordinated by four acetate anions and one isoquinoline molecule in a distorted square-pyramidal geometry; the Cu-II cation is 0.1681 (6) angstrom from the basal coordination plane formed by the four O atoms. Each acetate anion bridges two Cu-II cations to form the centrosymmetric dinuclear complex. Within the dinuclear molecule, the Cu center dot center dot center dot Cu separation is 2.6459 (4) angstrom. A parallel arrangement of isoquinoline ligands of adjacent complexes is observed in the crystal structure; the face-to-face distance of 3.610 (10) angstrom suggests there is no pi-pi stacking between isoquinoline ring systems.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant.

Isoquinoline

Isoquinoline, C9H7N, is a ligand which is used as a complexing agent for different metals. In order to compare geometric features of free isoquinoline and isoquinoline as a complexing ligand, we determined its crystal structure. Regrettably, the molecule is located on a centre of inversion and is therefore disordered; it is also isostructural with naphthalene. By refinement experiments and packing considerations, we were able to discard the possibility of fourfold disorder, which has been found for several beta-substituted naphthalene compounds, and performed the structure determination employing a model of twofold disorder.

Bio-Fe3O4-MNPs catalyzed green synthesis of pyrrolo[2,1-a]isoquinoline derivatives using isoquinolium bromide salts: study of antioxidant activity

In this research, a novel, one-pot, efficient procedure with high yield for the synthesis of pyrrolo[2,1-a]isoquinoline derivatives using multi-component reaction of isoquinoline, alkyl bromides, and triphenylphosphine in the presence of Fe3O4-MNPs as catalyst under solvent-free conditions at room temperature is investigated. This study highlights an easy, simple, rapid, and clean method for the preparation of pyrrolo[2,1-a]isoquinoline derivatives. The Fe3O4-MNPs in these reactions were produced employing a green procedure by reduction of ferric chloride solution with pomegranate peel water extract. Additionally, antioxidant activity was studied for the some newly synthesized compounds such as 5a-5d using the DPPH radical trapping and reducing potential of ferric ion experiments and comparing the results with the results of synthetic antioxidants (2-tert-butylhydroquinone, TBHQ; butylated hydroxytoluene, BHT). As a result, compounds 5a-5d show trace DPPH radical trapping and excellent reducing power of ferric ion.

Synthesis and photophysical insights of new fused N-heterocyclic derivatives with isoquinoline skeleton

Six new fused isoquinoline based compounds (compounds 5a-c with pyrrolo[2,1-a] isoquinoline structure and compounds 6a-c with imidazo[2,1-a]isoquinoline skeleton) have been synthesized using the [3 + 2] cycloaddition of the several in situ generated cycloimmonium ylides to ethyl propiolate or ethyl cyanoformate. All the synthesized compounds have been investigated in solution by UV-VIS absorption, steady and time-resolved fluorescence methods. The effect of the substituents on the spectral characteristics has been demonstrated. These derivatives displayed an intense emission between 360 and 420 nm. The emission quantum yields (Phi = 0.54-0.64) of pyrroloisoquinoline derivatives in dimethylsulfoxide (DMSO) were significantly higher than those of imidazoquinolines (0.03-0.16). The fluorescence decay of isoquinoline derivatives follows a biexponential law. A noticeable response of these isoquinoline derivatives to sodium hydroxide was observed. (C) 2020 Elsevier B.V.
