Alborixin
Alborixin is a polycyclic polyether ionophore Antibiotic. Alborixin is isolated from cultures of Streptomyces albus. Alborixin induces Autophagy via PTEN-mediated inhibition of the AKT pathway, thereby clearing Amyloid-β. Alborixin exhibits activity against Gram-positive bacteria and fungi. Alborixin can be used in the research of Alzheimer's disease.

Biological Activity
Alborixin (30-125 nM; 3-24 h) induces autophagy in mouse microglial N9 cells, with the maximal effect observed after treatment with 125 nM for 24 h; its mechanism of action involves upregulating LC3B-II levels, downregulating SQSTM1 levels, promoting GFP-LC3 puncta formation and increasing the number of autophagosomes[1].
Alborixin (125 nM) enhances soluble and fibrillar Aβ-induced autophagy in mouse microglial N9 cells, as evidenced by increased LC3B-II levels and decreased SQSTM1 levels[1].
Alborixin (125-250 nM; 12-24 h) eliminates soluble Aβ and fibrillary Aβ in mouse microglial N9 cells and human microglial HMC3 cells, and clears soluble Aβ in primary mouse neurons at 250 nM for 24 h. Its mechanism of action relies on the PTEN-AKT-dependent autophagy pathway, which requires functional ATG5 and BECN1[1].
Alborixin exhibits activity against Gram-positive bacteria and fungi[1].
