Synthesis of Isoquinoline-Fused Quinazolinones through Ag(I)-Catalyzed Cascade Annulation of 2-Aminobenzamides and 2-Alkynylbenzaldehydes

A new route for the expedient synthesis of a specific regioisomer of isoquinoline-fused quinazolinones is reported. Silver(I)-catalyzed cascade cyclization of 2-aminobenzamides and 2-alkynylbenzaldehydes followed by in situ oxidation gives 12-butyl- or 12-aryl-6 H -isoquinolino[2,1- a ]quinazolin-6-ones in 69-91% yields. The structure of the isoquinoline-fused quinazolinone was confirmed by X-ray crystallography analysis.

Microbial production of isoquinoline from indene

purified microbial isolate, identified as a strain of Rhodococcus sp., metabolized indene primarily to isoquinoline and lesser amounts of indandiol and indanone. lsoquinoline production was dependent on the presence of microbial culture, indene, and ammonium ions as the source of nitrogen in the molecule. The ability to produce isoquinoline was induced by growth on benzene or naphthalene and by the presence of indene itself. The culture produced compounds tentatively identified as 3-methylisoquinoline and 3-ethylisoquinoline from 2-methylindene and from 2-ethylindene, respectively. Deuterated indene was converted to deuterated isoquinoline, deuterated indanone, and deuterated indandiol. Experiments with [N-15]ammonium nitrate and ammonium [N-15]nitrate confirmed ammonium as the source of nitrogen in the isoquinoline products.

Isoquinoline derivatives as endogenous neurotoxins in the aetiology of Parkinson’s disease

The cause of neurodegeneration in Parkinson’s disease (PD) remains unknown. However, isoquinoline derivatives structurally related to the selective dopaminergic toxin 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) and its active metabolite, 1-methyl-4-phenylpyridinim (MPP+), have emerged as candidate endogenous neurotoxins causing nigral cell death in Parkinson’s disease. Isoquinoline derivatives are widely distributed in the environment, being present in many plants and foodstuffs, and readily cross the blood-brain barrier. These compounds occur naturally in human brain where they are synthesized by non enzymatic condensation of biogenic amines (e.g. catecholamines and phenylethylamine) with aldehydes, and are metabolized by cytochrome P450s and N-methyltransferases. In addition, isoquinoline derivatives are oxidized by monoamine oxidases to produce isoquinolinium cations with the concomitant generation of reactive oxygen species. Neutral and quaternary isoquinoline derivatives accumulate in dopaminergic nerve terminals via the dopamine re uptake system, for which they have moderate to poor affinity as substrates. Several isoquinoline derivatives are selective and more potent inhibitors of NADH ubiquinone reductase (complex I) and a-ketoglutarate dehydrogenase activity in mitochondrial fragments than MPP+, and lipophilicity appears to be important for complex I inhibition by isoquinoline derivatives. However, compared with MPP+, isoquinoline derivatives are selective but less potent inhibitors of NADH-linked respiration in intact mitochondria, and this appears to be a consequence of their rate-limiting ability to cross mitochondrial membranes. Although both active and passive processes are involved in the accumulation of isoquinoline derivatives in mitochondria, inhibition of respiration is determined by steric rather than electrostatic properties. Compared with 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine or MPP+, isoquinoline derivatives show selective but relatively weak toxicity to dopamine-containing cells in culture and following systemic or intracerebral administration to experimental animals, which appears to be a consequence of poor sequestration of isoquinoline derivatives by mitochondria and by dopamine-containing neurones. In conclusion, the 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine-like cytotoxic characteristics of isoquinoline derivatives and the endogenous/environmental presence of these compounds make it conceivable that high concentrations of and/or prolonged exposure to isoquinoline derivatives might cause neurodegeneration and Parkinson’s disease in humans.
