Cyclamides are a class of oligopeptides produced by cyanobacteria algae strains such as Microcystis aeruginosa. Some of them can be toxic.

Chemical structure of aerucyclamide A, a prototypical cyclamide

Cyclamides are cyclopeptides with either six or eight amino acids, some of which are modified from their natural proteinogenic form.[1] They are typically characterized by thiazole and oxazole rings which are thought to be cysteine and threonine derivatives, respectively.[1] Cyclamides are biosynthesized through ribosomic pathways.[2][3]
