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).

Synthesis, characterization and antimalarial activity of isoquinoline derivatives

This paper presents synthesis of novel decorated isoquinolines that can be used as antimalarial agents. Two series of compounds, isoquinoline phenyl and isoquinoline triazole derivatives, were synthesized via the Suzuki-Miyaura and Sharpless-Fokin reactions respectively. The final compounds were investigated for their antimalarial activity in cell-based experiments. In the series of isoquinoline phenyl derivatives, compound6exhibited interesting antiplasmodial activity against chloroquine resistant (K1) and chloroquine sensitive (3D7) strains ofP. Falciparumwith IC(50)1.91 +/- 0.21 mu M and 2.31 +/- 0.33 mu M, respectively. In the series of isoquinoline-triazole derivatives, compound15was the most active against resistant (K1) and sensitive (3D7) strains ofP. falciparumwith IC(50)4.55 +/- 0.10 mu M and 36.91 +/- 2.83 mu M, respectively. The respective resistance indices of compounds6and15against K1 and 3D7 were 0.83 and 0.12. Compound15was promisingly effective against the resistant strain. The results of this study provided useful contributions for further lead discovery and lead modification of modern rational drug design.
