title: Isoterreulactone A, a novel meroterpenoid with anti-acetylcholinesterase activity produced by Aspergillus terreus.
abstract: A new seven-membered lactone type meroterpenoid, isoterreulactone A, was isolated from the solid state fermentation of Aspergillus terreus and its structure was established by various spectral analysis. Isoterreulactone A inhibited acetylcholinesterase with an IC(50) value of 2.5 microM while did not inhibit butyrylcholinesterase even at 500 microM.
