Synthesis of regioisomeric difluoro- and 8-chloro-9-fluorobenz[g]isoquinoline-5,10-diones and SNAr displacements studies by diamines: bis(aminoalkyl)aminobenz[g]isoquinoline-5,10-diones

Convenient pathways have been developed for the synthesis of 6,7-, 6,8-, 7,9- and 8,9-difluorobenz[g] isoquinoline-5, 10-diones and 8 -chloro-9-fluorobenz[g] isoquinoline-5,10-dione. The crucial step in these synthesis involved the Ni-catalyzed coupling of the difluoro- or chlorofluorobenzylic zinc bromides with ethyl 3-chloroisonicotinate or ethyl 4-chloronicotinate. The reactions of the 6,7- or 8,9-difluoro regioisomers with N,N-dimethylethylenediamine led to quaternary salts which were formed by intramolecular displacements from the initial mono displacement products. These cyclizations could be obviated with the use of 3-dimethylaminopropylamine in the displacements which led to the desired bis(aminoalkyl) amino substitution products. Treatment of 8-chloro-9-fluorobenz [g]isoquinoline-5,10-dione with N,N-dimethylethylenediamine led to the regioselective displacement of fluoride. Treatment of this mono substitution product with excess N,N-dimethylethylenediamine led only to the intramolecular cyclization product which was also obtained by reaction of 8,9-difluorobenz[g] isoquinoline-9,10-dione with N,N-dimethyletfiylenediamine. The 6,8- and 7,9-difluoro analogues on treatment with N,N-dimethylethylenediamine or 3-dimethylaminopropylamine led to the expected bis substitution products.

Two New Isoquinoline Alkaloids from the Barks of Cassia fistula and Their Anti-Tobacco Mosaic Virus Activity

Two new isoquinoline alkaloids, fistulaquinolines A and B (1 and 2), were isolated from the barks of Cassia fistula. Their structures were determined by means of HR-ESI-MS and extensive 1D and 2D NMR spectroscopic studies. Compounds 1 and 2 were tested for their anti-tobacco mosaic virus (anti-TMV) activity. The results showed that the two compounds showed weak anti-TMV activity with inhibition rates of 18.9 and 22.6%.

Eleven isoquinoline alkaloids on inhibiting tissue factor activity: structure-activity relationships and molecular docking

Tissue factor (TF) which plays a key role in hemostasis and thrombosis appears to be an attractive target and medicinal plants having alkaloids inhibition TF activity benefit to cardiovascular disease (CVD). The aim of study is to explore further knowledge about alkaloids and TF. TF procoagulant activities were determined by the simplified chromogenic assay and their mRNA expression were then examined by reverse transcription and polymerase chain reaction. Besides, the potential of TF/FVIIa binding with four representative alkaloids were analyzed by molecular docking. The results indicated that these isoquinoline alkaloids with various structures had a different effect on suppression of TF activity. Molecular docking showed four alkaloids including L-corydalmine, berberine, jatrorrhizine, and tetrahydropalmatine were stably posed in the active binding pocket of TF/FVIIa. The SARs analysis showed the structural difference including planar, quaternary nitrogen, and the peripheral functional groups at C-8, C-9, C-10, have strong effect on inhibition of TF activity, which provided effective methods to modify isoquinoline alkaloids for inhibiting TF activity. This study provides a further evidence for the cardiovascular protection of isoquinoline alkaloids, and has physiological significance in the clinical challenge to use isoquinoline alkaloids or their potential analogs in the treatment of CVD.

Synthesis and Fluorescent Properties of Novel Isoquinoline Derivatives

Isoquinoline derivatives have attracted great interest for their wide biological and fluorescent properties. In the current study, we focused on the synthesis of a series of novel isoquinoline derivatives substituted at position 3 of the heteroaromatic ring. Compounds were obtained in a Goldberg-Ullmann-type coupling reaction with appropriate amides in the presence of copper(I) iodide, N,N-dimethylethylenediamine (DMEDA), and potassium carbonate. The structures of novel isoquinolines were confirmed by IR, NMR, and elemental analysis, as well as X-ray crystallography. In the course of our research work, the visible fluorescence of this class of compounds was observed. The above findings prompted us to investigate the optical properties of the selected compounds.

The studies of the adsorption behaviour of isoquinoline on a silver electrode

Adsorption behavior of isoquinoline on silver surface in HCl solution was studied using SERS spectra. The results show that isoquinoline is adsorbed on silver via Ag-N< interaction in a perpendicular orientation. As the applied voltage is shifted to -0.6 V, the strength of Ag-N< bond declines and the adsorption orientation is tilted.
