determined by the conversion of 1 to the methylester and the comparison of its specific rotation data with the two known methylester isomers, 2 and 3. Molecular sequencing with 16S rDNA indicated that this cyanobacterium differs from Caldora penicillata (Oscillatoriales) and represents a previously undocumented and novel Caldora species. Dysidazirine (2) showed weak cytotoxicity against HCT116 colorectal

Analogues of the antifungal marine natural product (E)-dysidazirine were prepared and evaluated in broth ro-dilution assays against a panel of fungal pathogens. A simple structure-activity relationship was developed which provides insight into the mechanism of action of long-chain 2H-azirine carboxylates. (C) 2010 Elsevier Ltd. All rights reserved.
