Synthesis of fused systems in the isoquinoline series: Oxazolo- and pyrrolo[3,2-c]isoquinolines

In order to synthesize the pyrrolo[3,2-c]isoquinoline structure, three different routes starting from readily available isoquinolines were tried. The ring closure reaction of a malonic derivative of 4-amino-3-bromoisoquinoline led to an oxazolo[3,2-c]isoquinoline instead of the target molecule. This latter was obtained via Sonagashira coupling reaction followed by ring closure under basic conditions. A study of the lithiation of the N-sulfonated pyrrolo[3,2-c]isoquinoline was undertaken. After optimization of the lithiation conditions, various 2-substituted pyrrolo[3,2-c]isoquinolines were obtained and their oxidation reactions studied.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 27655-40-9, you can contact me at any time and look forward to more communication. Formula: C9H7NO3S.

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.

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.
