Abstract

Biselyngbyaside, an 18-membered Macrolide glycoside from marine cyanobacteria, and its derivatives are known to be sarco/endoplasmic reticulum CA2+ ATPase (SERCA) inhibitors. Recently, a SERCA orthologue of the malaria Parasite, PfATP6, has attracted attention as a malarial drug target. To provide a novel drug lead, we designed new synthetic analogs of biselyngbyolide B, the aglycone of biselyngbyaside, based on the co-crystal structure of SERCA with biselyngbyolide B, and synthesized them using the established synthetic route for biselyngbyolide B. Their biological activities against malarial parasites were evaluated.
