ABSTRACT OF THE DISCLOSURE Several new, biologically active substances have been isolated from Hormothamnion enteromorphoides, a somewhat rare cyanophyte from Puerto Rico. Hormothamnion, a lipophilic metabolite from this alga, has the styrylchromone structure: Image Hormothamnion and, to a lesser extent, one of its homologs, are potent cytotoxins to some types of cancer cells and appear to exert this cytotoxic action by a selective inhibition of RNA synthesis. A peptide compound of about 11 to 12 amino acids has antimicrobial activity, particularly against Candida albicans. The peptide, which includes phenylalanine, serine and other aliphatic amino acids, has blocked carboxyl and amino termini.
