Design and Synthesis of Potent Antimalarial Agents Based on Clotrimazole Scaffold: Exploring an Innovative Pharmacophore
摘要:
Identification of new molecular scaffolds structurally unrelated to known antimalarials may represent a valid strategy to overcome resistance of P. falciparum (Pf) to currently available drugs. We describe herein the investigation of a new polycyclic pharmacophore, related to clotrimazole, to develop innovative antimalarial agents. This study allowed us to discover compounds characterized by a high in vitro potency, particularly against Pf CQ-resistant strains selectively targeting free heme, which are easy to synthesize by low-cost synthetic strategies.

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.
