Cytotoxic activity against three human cancer cell lines and inhibitory effect on CFTR-mediated chloride secretion in human intestinal epithelial (T84) cells of the three synthetic macrolides were evaluated. Mutolide displayed significant cytotoxic activity against HCT116 colon cancer cells (IC50 of ∼12 μM) as well as a potent CTFR inhibitory effect (IC50 of ∼1 μM).
