  Novel 3,4-methylenedioxyde-6-X-benzaldehyde-thiosemicarbazones: Synthesis and antileishmanial effects against Leishmania amazonensis

  摘要：

  A series of eleven 3,4-methylenedioxyde-6-X-benzaldehyde-thiosemicarbazones (16-27) was synthesised as part of a study to search for potential new drugs with a leishmanicidal effect. The thiosemicarbazones, ten of which are new compounds, were prepared in good yields (85-98%) by the reaction of 3,4-methylenedioxyde-6-benzaldehydes (6-X-piperonal), previously synthesised for this work by several methodologies, and thiosemicarbazide in ethanol with a few drops of H2SO4. These compounds were evaluated against Leishmania amazonensis promastigotes, and derivatives where X = I (22) and X = CN (23) moieties showed impressive results, having IC50 = 20.74 mu M and 16.40 mu M, respectively. The intracellular amastigotes assays showed IC50 = 22.00 mu M (22) and 17.00 mu M (23), and selectivity index >5.7 and >7.4, respectively, with a lower toxicity compared to pentamidine (positive control, SI = 4.5). The results obtained from the preliminary QSAR study indicated the hydrophobicity (log P) as a fundamental parameter for the 2D-QSAR linear model. A molecular docking study demonstrated that both compounds interact with flavin mononucleotide (FMN), important binding site of NO synthase. (C) 2015 Elsevier Masson SAS. All rights reserved.

  Benzo[c]phenanthridine alkaloids oxynitidine and oxysanguinarine were synthesized from easily available starting benzonitrile 5 and toluamide 6 using toluamide–benzonitrile cycloaddition reaction in six steps. This method is so highly efficient that it could be a more useful way for preparing fully aromatized benzo[c]phenanthridine compounds.

  A new versatile synthesis of benzo[c]phenanthridine and protoberberine alkaloids using lithiated toluamide−benzonitrile cycloaddition was carried out. The coupling reaction between benzonitrile 6 with o-toluamides (8a−c) afforded 3-arylisoquinolines (9a−c) that were transformed to the protoberberines (11a−c) or benzo[c]phenanthridines (14a−c). These compounds were synthesized by ring closure of the

  Treatment of benzocyclobuten-2-ols with MeLi affords o-tolualdehyde anions which in the presence of nitriles cyclize to 3-substituted isoquinolines. Examples include the synthesis of the alkaloid hypecumine from the precursors, 14 and 19 (1:1), in 50% yield.
