• Targeting the human malaria parasite Plasmodium falciparum: In vitro identification of a new antiplasmodial hit in 4-phenoxy-2-trichloromethylquinazoline series

  From the promising results we previously obtained in quinazoline series and to complete the evaluation of the in vitro antiplasmodial activity of original 2-trichloromethylquinazolines, we synthesized new quinazolines possessing a variously substituted phenoxy group at position 4 through a simple and efficient two-step-synthesis approach. The studies of their activity toward the multi-resistant W2 Plasmodium falciparum strain and of their cytotoxicity on the human hepatocyte HepG2 cell line highlighted a hit compound (molecule 7) displaying a W2 IC(50) value of 1.1 mu M and a HepG2 CC(50) value of 50 mu M, comparable to chloroquine and doxycycline. Structure-activity- and toxicity relationships indicate that the trichloromethyl group plays a key role in the antiplasmodial activity of such chemical scaffold and also that the phenoxy group substitution as a direct influence on the molecules selectivity. Moreover, molecule 7 displays significant specific activity against the Plasmodium genus in comparison with Toxoplasma and does not show any mutagenic property at the Ames test.

  The latest scientific findings concerning PDE7 and PDE4 inhibition suggest that selective small-molecule inhibitors of both enzymes could provide a novel approach to treat a variety of immunological diseases. In this context, we describe a new series of quinazoline derivatives from quinazolin-4-thiones which include a substituted biphenyl fragment. Some of these compounds show inhibitory potencies at sub-micromolar levels against the catalytic domain of PDE7. (C) 2013 Elsevier Ltd. All rights reserved.
• Sonogashira cross-coupling reaction in 4-chloro-2-trichloromethylquinazoline series is possible despite a side dimerization reaction

  We studied the Sonogashira coupling reaction between 4-chloro-2-trichloromethylquinazoline and various terminal alkynes, mainly in phenylacetylene series. A brief review of the literature shows that mono- or polybromo/chloromethylated substrates, especially in aromatic series, are very rarely compatible with the achievement of Sonogashira reactions. Thus, although the 4-chloroquinazoline scaffold is a very good substrate for this palladium-catalyzed reaction, the typical behavior of the trichloromethyl group in reductive media leads to the competitive formation of undesirable reduced homodimers in high yields. However, by closely examining all the Sonogashira reaction parameters, we developed a specific operating procedure, using Pd(OAc)(2), Cs2CO3, and DMF, which resulted in the synthesis of 14 original coupling products in 10-70% yield, depending on the alkyne used.
