Two new epimers of malyngamide C, 8-O-acetyl-8-epi-malyngamide C (1) and 8-epi-malyngamide C (3) have been isolated along with known compounds 6-O-acetylmalyngamide F (5), H (6), J (7) K (8), and characterized from a Grenada field collection of the marine cyanobacterium Lyngbya majuscula. The planar structures of these compounds were deduced by 1D- and 2D-NMR and mass spectral data interpretation. The absolute configurations were determined by a combination of CD-spectroscopy, chemical degradation and the variable temperature Mosher’s method. Compounds 1–5, 7 and 8 displayed moderate cytotoxicity to NCI-H460 human lung tumor and neuro-2a cancer cell lines, with IC50 values ranging between 0.5 and 20 μg/mL.
