5-Phenyllevulinic acid (4-Oxo-5-phenylpentanoic acid) is an endogenous fungal metabolite with inhibitory activity against the bacterium B. megaterium, the plant pathogenic fungus S. tritici, and the alga C. fusca. 5-Phenyllevulinic acid is also an intermediate in the synthesis of sigma receptor ligands. 5-Phenyllevulinic acid holds potential for research in the field of anti-infection studies [2].
