Limacella illinita Bioactive Compounds

A study in 2007 discovered four new bioactive compounds from basidiomycetes, isolated from fermentations of L. illinita: Illinitone A that exhibited weak phytotoxic and moderate nematicidal activities against Caenorhabditis elegans, Illinitone B was moderately cytotoxic, Limacellone that exhibited weak cytotoxic and phytotoxic activities and muurolane sesquiterpene 4a that was found to be inactive in the assays performed there.
