Significance

The crambescidins are sponge metabolites with nanomolar cytotoxicity against several tumour cell lines and they display antifungal activity (Candida albicans), antiviral activity (herpes simplex) and anti-HIV activity. Aron and Overman synthesized Crambescidins 359 and 431 and a small library of unnatural compounds with variations in the side chain at C14. They provide the first detailed description of the physical and chemical properties of this class of guanidinium alkaloids.
