Vacuolin-1

Research use only, not for human use.

A potent PIKfyve inhibitor that inhibits autophagy by impairing lysosomal maturation, potently and reversibly inhibits autophagosome-lysosome fusion by activating RAB5A.

A potent PIKfyve inhibitor that inhibits autophagy by impairing lysosomal maturation, potently and reversibly inhibits autophagosome-lysosome fusion by activating RAB5A; blocks the Ca(2+)-dependent exocytosis of lysosomes induced by ionomycin or plasma membrane wounding, without affecting the process of resealing, induces the formation of giant vacuoles.

Vacuolin-1 (1 μM; Pretreatment 1 hour) blocks ionomycin-induced exocytosis of lysosomes but not of enlargeosomes. It results in vacuolation of lysosomes (A) and complete inhibition of the surface expression of Lamp-1. Vacuolin-1 (1 μM; 20-180 min) disrupts the segregation of inner and limiting membranes characteristic of endosomes and lysosomes. Ultrastructural analysis also shows that vacuolin-1 favours fusion of inner and limiting membranes.Vacuolin-1 (5 or 10 μM; 2 hours) blocks the Ca2+-dependent release of β-hexosaminidase from lysosomes. In HeLa cells, ionomycin results in the expected release of 18-20% of lysosomal β-hexosaminidase. But when cells pretreated with vacuolin-1, releases no more β-hexosaminidase compared with cells that are not exposed to ionomycin (4%).
