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.

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.

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.

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).

Simultaneous quantification of 11 isoquinoline alkaloids in Corydalis impatiens (Pall.) Fisch by HPLC

Isoquinoline alkaloids are the primary active ingredients of Corydalis, but an analytical method for quality assessment of the active ingredients in Corydalis impatiens (Pall). Fisch has not been reported. A new, simple, and multiple-component quantification method was developed for the simultaneous quantification of 11 isoquinoline alkaloids including capnoidine, chelianthifoline, bicuculline, protopine, isoapocavidine, apocavidine, cavidine, tetrahydroepiberberine, ochotensimine, tetrahydrocoptisine, and tetrahydrocorysamine in C. impatiens. Separation of the isoquinoline alkaloids was performed on a RP C-18 column (150 x 4.6 mm, 5 m) with potassium dihydrogen phosphate buffer (pH 2.5, adjusted by phosphoric acid)/acetonitrile (53:47, v/v) containing 0.3% sodium dodecyl sulfonate. The flow rate and detection wavelength were set at 1 mL/min and 295 nm, respectively. Full validation of the assay was carried out including linearity, precision, accuracy, stability, LOD, and limit of quantitation. All calibration curves showed a good linear relationship (r > 0.999) in test range. The results demonstrated that the developed method was reliable, rapid, and specific. Six batches of C. impatiens samples from different sources were determined using the established method. The contents of alkaloids ranged from 11.68 to 351.83 g/g. This method can be applied for quality evaluation and control of C. impatiens. Eleven isoquinoline alkaloids were first reported on simultaneous determination with HPLC.
