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.

In Vitro

Pseurotin A inhibits the expression of PCSK9 in HepG2 cells, with an IC50 value of 1.2 μM[3].
Pseurotin A (25-100 μM; 72 hours) significantly suppresses the PCSK9 level in a dose dependent manner in BT-474 and T47D BC cell lines[3].
Pseurotin A (25-100 μM; 72 hours) significantly increases LDLR level in a dose dependent manner[3].
Pseurotin A (40-200 μM; 24-72 hours) shows anti-proliferative activity in the hormone-dependent BC cells[3].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
