pseurotin A

Pseurotin A is a fungal secondary metabolite, originally isolated from *Aspergillus fumigatus*, that has emerged as a multi-target therapeutic lead entity. It functions as a dual inhibitor of proprotein convertase subtilisin/kexin type 9 (PCSK9), targeting both its secretion and its protein-protein interaction (PPI) with the low-density lipoprotein receptor (LDLR). This dual mechanism suggests significant potential for the management of hypercholesterolemia. Furthermore, Pseurotin A has demonstrated potent activity in suppressing the recurrence of metastatic castration-resistant prostate cancer (mCRPC) in preclinical models. Its anti-tumor effects are characterized by the promotion of tumor apoptosis and the inhibition of cell invasion and migration, likely mediated through the modulation of the ubiquitin-proteasome system. Preclinical evaluations indicate a favorable safety profile and rapid intravenous distribution, although the molecule does not cross the blood-brain barrier.
