Abstract

A series of artemisinin derived esters 7a–j, incorporating pharmacologically privileged substructure, such as biphenyl, adamantane and fluorene, have been prepared and evaluated for antimalarial activity against multidrug-resistant (MDR) Plasmodium yoelii nigeriensis by oral route. Several of these compounds were found to be more active than the antimalarial drugs β-arteether 4 and artesunic acid 5. Ester 7i, the most active compound of the series, provided 100% and 80% protection to the infected mice at 24 mg/kg × 4 days and 12 mg/kg × 4 days, respectively. In this model β-arteether provided 100% and 20% protection at 48 mg/kg × 4 days and 24 mg/kg × 4 days, respectively.
