Secochiliolide ester derivatives: Preparation and evaluation of their antitrypanosomal and antimalarial efficacy
In the present study, a series of new esters of secochiliolide acid (SA), a diterpene isolated from Nardophyllum bryoides, were synthesized in good yield. All compounds were evaluated for their in vitro antiparasitic properties (on Plasmodium falciparum and Trypanosoma brucei brucei) and cytotoxicit...
