Inhibition of [H-3]dopamine uptake into striatal synaptosomes by isoquinoline derivatives structurally related to 1-methyl-4-phenyl-1,2,3,6 tetrahydropyridine

Isoquinoline derivatives structurally related to 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) or 1-methyl-4-phenylpyridinium (MPP(+)) may be endogenous neurotoxins causing nigral cell death in Parkinson’s disease. These compounds inhibit mitochondrial function but, like MPP(+), require accumulation in dopaminergic neurones via the dopamine reuptake system to exert toxicity. We, now, examine the substrate affinity of 14 neutral and quaternary isoquinoline derivatives (7 isoquinolines, 2 dihydroisoquinolines and 5 1,2,3,4-tetrahydroisoquinolines) for the dopamine reuptake system by their ability to inhibit the uptake of [H-3]dopamine into rat striatal synaptosomes. Ten isoquinoline derivatives and MPP+ inhibited [H-3]dopamine uptake in a concentration-dependent manner. Only 5 isoquinoline derivatives produced 50% inhibition of [H-3]dopamine uptake (IC50 = 8.0-50.0 mu M), none of which were as potent as MPP(+) (IC50 = 0.33 mu M). These findings suggest that isoquinoline derivatives are moderate to poor substrates for the dopamine reuptake system and that high concentrations of, or prolonged exposure to, isoquinoline derivatives may be necessary to cause neurodegeneration.

Crystal structure of 2-(1,3-dioxoindan-2-yl)isoquinoline-1,3,4-trione

In the title isoquinoline-1,3,4-trione derivative, C18H9NO5, the five-membered ring of the indane fragment adopts an envelope conformation with the nitrogen-substituted C atom being the flap. The planes of the indane benzene ring and the isoquinoline-1,3,4-trione ring make a dihedral angle of 82.06 (6)degrees. In the crystal, molecules are linked into chains extending along the bc plane via C-H center dot center dot center dot O hydrogen-bonding interactions, enclosing R-2(2)(8) and R-2(2)(10) loops. The chains are further connected by pi-pi stacking interations, with centroid-to-centroid distances of 3.9050 (7) angstrom, forming layers parallel to the b axis.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 27655-40-9. Application In Synthesis of Isoquinoline-5-sulfonic acid.

Total Syntheses of Menisporphine and Daurioxoisoporphine C Enabled by Photoredox-Catalyzed Direct C-H Arylation of Isoquinoline with Aryldiazonium Salt

Isoquinoline alkaloids are attractive natural products due to their diverse chemical structures as well as remarkable bioactivities. Herein, we report the concise total syntheses of two isoquinoline alkaloids, menisporphine and daurioxoisoporphine C, through a mild and efficient photoredox-catalyzed direct C-H arylation of isoquinoline core with aryldiazonium salt. This new strategy is complementary to the conventional isoquinoline synthesis and would provide us a useful means to achieve a more convergent and flexible approach to access diverse isoquinoline structures.

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.

Cyano-Sacrificial (Arylthio)arylamination of Quinoline and Isoquinoline N-Oxides Using N-(2-(Arylthio)aryl)cyanamides

A copper(I)-catalyzed regioselective arylthio-arylamination of quinoline and isoquinoline N-oxides has been achieved at the expense of a cyano (CN) group from N-(2-(arylthio)aryl)cyanamides. This reductive amination proceeds in one pot at 80 degrees C in the absence of any additives.

Synthesis of Antifungal Evaluation of 2H-[1,2,3]Triazolo[4,5-g]isoquinoline-4,9-diones

2H-[1,2,3]Triazolo[4,5-g]isoquinoline-4,9-diones and 2H-[1,2,3]triazolo[4,5-g]quinoline-4,9-diones were synthesized and tested for in vitro antifungal activity against pathogenic fungi. Many of those synthesized showed potent antifungal activity. Compounds 3a, 3b, 3g, and 3h completely inhibited the growth of all fungal species tested at the MIC level of 0.8-12.5 mu g/mL. The results suggest that 2H-[1,2,3]triazolo[4,5-g]-isoquinoline-4,9-diones could be antifungal agents.
