Full textMalaria remains the leading cause of death among parasitic infections worldwide. Currently, there are major concerns about the spread of resistance to artemisinin derivatives that are the basis of first-line antimalarial treatment. Therefore, there is an urgent need to develop new antiplasmodial molecules with a novel mechanism of action. For this purpose, our laboratory has previously described the synthesis and biological activities of a chemical library of α-trichloromethylated azaheterocycles including a hit molecule in the quinazoline series which presents the best biological profile.The first part of this work focused on 4-carboxamide quinazoline pharmacomodulation. In order to complete the SARs, scaffold hopping strategies allowed us to obtain new compounds in the quinoxaline and phthalazine series. By structural simplification, new compounds in the pyrimidine, pyridazine and pyrazine series were obtained. Finally, in order to explore the benzene part of the quinazoline and quinoxaline rings, new thienopyrimidine and pyrido[2,3-b]pyrazine derivatives were also synthesized. More than 110 new original molecules were obtained, among them several new hit molecules were obtained. The physicochemical and in vitro pharmacokinetic properties were determined in order to initiate the study of their in vivo activity on Plasmodium berghei. In addition, in order to elucidate the mechanism of action of these compounds, which differs from those of commercial antimalarials, we have recently identified by immunofluorescence that these molecules target the apicoplast of P. falciparum, an organelle essential to parasite survival

Full textThe objective of this work consists of the synthesis and the antiparasitic in vitro evaluation of new thiazole derivatives and related structures. Several synthetic strategies aiming at the pharmacomodulation on mono- and polycyclic series have been studied: in 2-methyl-5-nitrothiazole series, the anti-Trichomonas pharmacomodulation on position 4 by SRN1 strategy did not improve the activity previously demonstrated in 2-methyl-5-nitroimidazole series, but led to derivatives displaying a selective in vitro antiproliferative activity toward the HepG2 cell line. In 4-arylsulfonylmethyl-2-methylthiazole series, the pharmacomodulation on position 5, by Suzuki-Miyaura cross-coupling reaction on the one hand, and by direct arylation and intramolecular Knoevenagel reaction on the other hand, led to mono- and polycyclic derivatives among which some displayed an encouraging in vitro antiplasmodial activity. In 5H-thiazolo[3,2-a]pyrimidin-5-one series, a double Suzuki-Miyaura cross-coupling reaction revealed that the phenyl group on position 6 contributes to the antiplasmodial effect of this series. Finally, the in vitro biological evaluation of the thieno[3,2-d]pyrimidin-4(3H)-one scaffold let to characterize the pharmacophore responsible for the significant antiplasmodial activity. Some preliminary encouraging results regarding a mechanistic antiplasmodial study show the specific inhibition of plasmodial kinases, as a potential mechanism of action of some of these compounds

Full textThis work focuses on the synthesis of new bioactive quinazoline derivatives under microwave irradiation. In the first chapter, we indicate the main methods for preparing the quinazoline ring, the pharmacological properties associated to the quinazoline-derivated drug compounds and we present the SRN1 reaction updated bibliography. In the second chapter, the synthesis and reactivity of 2-chloromethyl-3-methylquinazolin-4(3H)-one with nitronate and sulfinate anions are successively described. A mechanistic study permits to demonstrate the SRN1 radical chain mechanism for the reaction with nitronate anions and a SN2 one for sulfinate anions. Afterwards, we prepared new original quinazolines, under microwave irradiation, by studying SNAr and Suzuki-Miyaura coupling reactions in 4-chloroquinazoline series. From these results, we have developed a regioselective Suzuki-Miyaura reaction on the 4,7-dichloro-2-(2-methylprop-1-enyl)-6-nitroquinazoline and prepared a new series of highly functionalized 4,7-diarylquinazolines. Finally, the biological evaluation of the products prepared by SNAr, showed interesting antiplasmodial and anti-leishmania activities along with EGFR1 inhibition properties
