. Chemicals that inhibit prolyl endopeptidase have attracted research interest due to their potential therapeutic effects.
Several kynapcins have been found in ''P. multiplex'', each with different
chemical properties, including kynapcin-12,
kynapcin-13 and -28,
and -24. A
total synthesis of kynapcin-24 was achieved in 2009.
