We report in vivo and in vitro antileishmanial and trypanocidal activities of a new series of N-substituted benzene and naphthalenesulfonamides 1-15. Compounds 1-15 were screened in vitro against Leishmania infantum, Leishmania braziliensis, Leishmania guyanensis, Leishmania amazonensis, and Trypanosoma cruzi. Sulfonamides 6e, 10b, and 10d displayed remarkable activity and selectivity toward T. cruzi epimastigotes and amastigotes. 6e showed significant trypanocidal activity on parasitemia in a murine model of acute Chagas disease. Moreover, 6e, 8c, 9c, 12c, and 14d displayed interesting IC50 values against Leishmania spp promastigotes as well as L. amazonensis and L. infantum amastigotes. 9c showed excellent in vivo activity (up to 97% inhibition of the parasite growth) in a short-term treatment murine model for acute infection by L. infantum. In addition, the effect of compounds 9c and 14d on tubulin as potential target was assessed by confocal microscopy analysis applied to L. infantum promastigotes.

Non-symmetrical 2,3-disubstituted quinoxalines are not easily obtained in good yields because of the lack of regioselectivity of the Hinsberg condensation, or the large number of steps required for achieving their preparation. Two efficient methods leading to non-symmetrical 2,3-disubstituted quinoxalines, carried out in smooth conditions, have been developed in our laboratory. These methods enable the synthesis of pharmacologically active quinoxaline derivatives.

Parkinson disease is a neurodegenerative disorder of aging, characterized by disabling motor symptoms resulting from the loss of midbrain dopaminergic neurons and the decrease of dopamine in the striatum. Current therapies are directed at treating the symptoms but there is presently no cure for the disease. In order to discover neuroprotective compounds with a therapeutical potential, our research team has established original and highly regioselective methods for the synthesis of 2,3-disubstituted 6-aminoquinoxalines. To evaluate the neuroprotective activity of these molecules, we used midbrain cultures and various experimental conditions that promote dopaminergic cell loss. Among a series of 11 molecules, only compound MPAQ (2-methyl-3-phenyl-6-aminoquinoxaline) afforded substantial protection in a paradigm where dopaminergic neurons die spontaneously and progressively as they mature. Prediction of blood-brain barrier permeation by Quantitative Structure-Activity Relationship studies (QSARs) suggested that MPAQ was able to reach the brain parenchyma with sufficient efficacy. HPLC-MS/MS quantification in brain homogenates and MALDI-TOF mass spectrometry imaging on brain tissue sections performed in MPAQ-treated mice allowed us to confirm this prediction and to demonstrate, by MALDI-TOF mass spectrometry imaging, that MPAQ was localized in areas containing vulnerable neurons and/or their terminals. Of interest, MPAQ also rescued dopaminergic neurons, which (i) acquired dependency on the trophic peptide GDNF for their survival or (ii) underwent oxidative stress-mediated insults mediated by catalytically active iron. In summary, MPAQ possesses an interesting pharmacological profile as it penetrates the brain parenchyma and counteracts mechanisms possibly contributive to dopaminergic cell death in Parkinson disease.

A class of N-(naphthalen-1-yl)-N?-alkyl oxalamides have been proven to be powerful ligands, making a coupling reaction of (hetero)aryl iodides with primary amines proceed at 50 C with only 0.01 mol % of Cu2O and ligand as well as a coupling reaction of (hetero)aryl bromides with primary amines and ammonia at 80 C with only 0.1 mol % of Cu2O and ligand. A wide range of coupling partners work well under these conditions, thereby providing an easy to operate method for preparing (hetero)aryl amines.
