unsaturated fatty acid (E)-7,9-dimethylundec-2-enoic acid was assigned in 3. The 3R configuration of the stereocenter of 3-β-hydroxy fatty acids in 1 and 2 was established by Mosher's MTPA method. The absolute stereochemistry of amino acid residues in 1-3 was ascertained by acid hydrolysis followed by Marfey's derivatization studies. Gageostatins 1-3 exhibited good antifungal activities with MICs values
