N2 - Borrelidin, a structurally unique 18-membered macrolide, was found to express antimalarial activity against drug-resistant Plasmodium falciparum malaria parasites, with IC50 value of 0.93 ng/mL. However, it also displays strong cytotoxicity against human diploid embryonic MRC-5 cells. To investigate the issue of the cytotoxicity of borrelidin, borrelidin-based analogues were synthesized and their anti-Plasmodium properties were evaluated. In this communication, we report that a novel borrelidin analogue, bearing the CH2SPh moiety via a triazole linkage, was found to retain a potent antimalarial activity, against drug-sensitive and drug-resistant parasite strains, but possess only weak cytotoxicity against human cells.
