生物活性:
Pseurotin A, a secondary metabolite of Aspergillus and other fungi, is a competitive inhibitor of chitin synthase and a neuritogenic agent. Pseurotin A inhibits IgE production (IC50=3.6 μM). Antitumor activity.

体内研究:
Pseurotin A (10 mg/kg; p.o.; 7X/week, 30 days) shows anti-tumor activity.Animal Model:HFD-fed orthotopic athymic mice (bearing BT-474 tumor cells xenograft mode)
Dosage:10 mg/kg
Administration:P.o.; 7X/week, 30 days
Result:Significantly suppressed the growth of BT474 tumors.

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