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[1][2][3].

体外研究
(In Vitro)

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[3].
Pseurotin A (40-200 μM; 24-72 hours) shows anti-proliferative activity in the hormone-dependent BC cells[3].

Cell Viability Assay[3]

Cell Line: BT-474 cells, T47D cells
Concentration: 40-200 μM
Incubation Time: 24-72 hours
Result: Showed weak but time and dose-dependent inhibition of the growth of BT-474 and T47D BC cells, with gradual decrease of the IC50 values over time (260.83-93.64 μM and 267.84-113.08 μM, respectively).

体内研究
(In Vivo)

Pseurotin A (10 mg/kg; p.o.; 7X/week, 30 days) shows anti-tumor activity[3].

Animal Model: HFD-fed orthotopic athymic mice (bearing BT-474 tumor cells xenograft mode)[1]
Dosage: 10 mg/kg
Administration: P.o.; 7X/week, 30 days
Result: Significantly suppressed the growth of BT474 tumors.
