Synthesis of 1-substituted 1,2,3,4-tetrahydrobenz[g]isoquinoline-5,10-diones

1,2-Disubstituted 1,2,3,4-tetrahydrobenz[g]isoquinoline-5,10-diones are prepared for the first time through an activated Pictet-Spengler reaction of the corresponding imines of 2-(1,4-dimethoxynaphth-2-yl)ethylamine in the presence of an acyl chloride and AlCl3 followed by an oxidation with silver(II) oxide in nitric acid. Depending on the reaction conditions the N-trichloroacetyl protecting group could be cleaved off, converted to an N-methoxycarbonyl group or transformed to an N-(2-oxoacetamide) moiety. The synthesized 1,2-disubstituted 1,2,3,4-tetrahydrobenz[g]isoquinoline-5,10-diones constitute a new class of quinones, which has not been reported yet.

Discovery of 4,6-and 5,7-Disubstituted Isoquinoline Derivatives as a Novel Class of Protein Kinase C zeta Inhibitors with Fragment-Merging Strategy

Two chemical series of novel protein kinase C zeta (PKC zeta) inhibitors, 4,6-disubstituted and 5,7-disubstituted isoquinolines, were rapidly identified using our fragment merging strategy. This methodology involves biochemical screening of a high concentration of a monosubstituted isoquinoline fragment library, then merging hit isoquinoline fragments into a single compound. Our strategy can be applied to the discovery of other challenging kinase inhibitors without protein-ligand structural information. Furthermore, our optimization effort identified the highly potent and orally available 5,7-isoquinoline 37 from the second chemical series. Compound 37 showed good efficacy in a mouse collagen-induced arthritis model. The in vivo studies suggest that PKC zeta inhibition is a novel target for rheumatoid arthritis (RA) and that 5,7-disubstituted isoquinoline 37 has the potential to elucidate the biological consequences of PKC zeta inhibition, specifically in terms of therapeutic intervention for RA.

Alkaloids and a flavonoid from aerial parts (leaves and twigs) of Duguetia furfuracea – Annonaceae

Duguetia furfuracea is a shrub of the Annonaceae family that occurs in several regions in Brazil. In the state of Mato Grosso do Sul this species often becomes an invading plant when the cerrado is turned into pastures. In the local folk medicine, its powdered seeds are mixed with water and used against pediculosis. and the infusion of twigs and leaves is used to treat rheumatism.. The present work led to the isolation and characterization from the aerial parts of the plant (leaves and twigs), of twelve isoquinoline alkaloids of aporphine oxoaporphine, bisbenzyltetrahydro-isoquinoline, benzyltetrahydro-isoquinoline and tetrahydroprotoberberine skeletons. In addition beta-sytosterol and the flavonoid isorhamnethin were obtained. The activity of these different patterns of isoquinoline skeleton and the flavonoid was tested against Trypanosoma cruzi, and only aporphinoid skeleton with (R)-configuration, (-)-asimilobine, was really effective against trypomastigotes (strain Y), killing approximately 72% of the parasites at a maximal concentration of 128.0 mu M (IC50 57.2 mu M). The trypanocidal activity of the alkaloids and the flavonoid have been investigated.

HETEROATOM-DIRECTED LATERAL LITHIATION – SYNTHESIS OF ISOQUINOLINE DERIVATIVES FROM N-(TERT-BUTOXYCARBONYL)-2-METHYLBENZYLAMINES

Methodology for the preparation of isoquinoline derivatives from N-(tert-butoxycarbonyl)-2-methylbenzylamines (1) was developed. Conversion of 1 to the dilithio species followed by condensation with DMF afforded Boc-3-hydroxy-1,2-3,4-tetrahydroisoquinolines 3, which could be dehydrated to 1,2-dihydroisoquinolines 4. Hydrogenation of dihydro compounds 4 afforded the corresponding tetrahydroisoquinolines 5. Treatment of the dilithio species from 1 with N-methoxy-N-methylamides afforded ketones 15, which were converted to 3-substituted dihydro-isoquinoline 15, tetrahydroisoquinolines (16,17), or isoquinolines (20).

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 17557-76-5 is helpful to your research. Recommanded Product: 17557-76-5.

Vasorelaxant effect of isoquinoline derivatives from two species of Popowia perakensis and Phaeanthus crassipetalus on rat aortic artery

Five bisbenzyl isoquinolines (1-5), three benzyl isoquinolines (6-8), four isoquinoline alkaloids (9-12), and two unclassified compounds (13 and 14) from Popowia perakensis and Phaeanthus crassipetalus were evaluated for their vasorelaxant effect on rat aortic arteries. In aortic rings pre-contracted with phenylephrine (PE, 0.3 mu M), some of the bisbenzyl isoquinoline alkaloids, benzyl isoquinoline alkaloids, and isoquinoline alkaloids showed clearly vasorelaxant effects at 30 mu M. The action of (-)-limacine (4) was deduced to be mediated through the increased release of NO from endothelial cells, and that of pecrassipine A (7) and backebergine (12) partly mediated by NO release. Further, the action of pecrassipine A (7) and backebergine (12) may be attributed to their inhibition of the voltage-dependent Ca2+ channel and receptor-operated Ca2+ channel.

An effective route to functionalized 1,2,3, 10b-tetrahy-dropyrrolo[2,1-a]isoquinoline-1-carboxamide derivatives is described. This involves reaction of N-alkyl-3-oxobutanamides, which result from the addition of amines to diketene, and dibenzoyl-acetylene in the presence of isoquinoline. The reactive]:I intermediate obtained from the addition of isoquinoline to dibenzoyl-acetylene is trapped by OH acids such as N-alkyl-3-oxobutanamides to produce the pyrrolo[2,1-a]isoquinoline-l-carboxamide derivatives.
