Exploring clotrimazole-based pharmacophore: 3D-QSAR studies and synthesis of novel antiplasmodial agents
摘要:
We report herein the generation and validation of a 3D-QSAR model based on a set of antimalarials previously described by us and characterized by a clotrimazole-based pharmacophore. A novel series of derivatives was synthesized and showed activity against Plasmodium falciparum chloroquine-sensitive (CQ-S) and chloroquine-resistant (CQ-R) strains. Gratifyingly, compounds 35a-c showed interesting activity against P. falciparum CQ-R strains with improved predicted physico-chemical properties. (C) 2015 Elsevier Ltd. All rights reserved.

the treatment of infections. We recently reported the development of a novel antimalarial drug that combines the 4-aminoquinoline pharmacophore of chloroquine with that of clotrimazole-based antimalarials. Here we describe the optimization of this class of hybrid drug through in-depth structure–activityrelationshipstudies. Antiplasmodial properties and mode of action were characterized in vitro and

[EN] Antimalarial agents having a novel pharmacophore of formula (I) are herein described. These polycyclic compounds are able to inhibit chloroquine-sensitive and chloroquine-resistant strains ofPlasmodium falciparum (Pf). Furthermore, the synthesis of these compounds involves few steps from commercial products with low cost of production. [FR] La présente invention concerne des agents antimalariaux comportant un nouveau pharmacophore de formule (I). Ces composés polycycliques sont susceptibles d'inhiber les souches sensibles à la chloroquine et résistantes à la chloroquine de Plasmodium falciparum (Pf). En outre, la synthèse de ces composés est peu onéreuse et implique peu d'étapes à partir des produits commerciaux.
