Symplocamide A is a newly discovered (2008) 3-amino-6-hydroxy-2-piperidone (Ahp) cyclodepsipeptide that has been isolated from a marine cyanobacteria in Papua New Guinea, which has only been identified at the genus level (Symploca).[2] Cyanobacteria, both freshwater and marine, are known as producers of diverse protease inhibitors that may be used to treat diseases, such as HIV, and some forms of cancer. Research on symplocamide A has shown that it is a strong serine protease inhibitor and has a high level of cytotoxicity to cancer cells when used in vitro.[3] As of the time of this writing, its use as a treatment on human participants has not been done and future study will have to be done before any human testing can be commenced.
