Pseurotin A

Pseurotin A is a secondary metabolite of Aspergillus and other fungi. Pseurotin A is a competitive inhibitor of chitin synthase and a neuritogenic agent. Pseurotin A inhibits IgE production (IC50 = 3.6 μM) . Pseurotin A inhibits the PCSK9-LDLr interaction. Pseurotin A shows dose-dependent reduction of PCSK9, along with increased LDLR levels in hormone-dependent breast cancer cell lines. Pseurotin A exhibits antitumor activity[1][2][3].
