Metabolite Identification
Common NameAnidulafungin
DescriptionAnidulafungin, also known as eraxis, belongs to the class of organic compounds known as oligopeptides. These are organic compounds containing a sequence of between three and ten alpha-amino acids joined by peptide bonds. Anidulafungin is a drug. Anidulafungin is an extremely weak basic (essentially neutral) compound (based on its pKa). Anidulafungin is a potentially toxic compound.
