ML-SA5 is an MCOLN1 agonist and arrests autophagic flux by perturbing fusion between autophagosomes and lysosomes.
Activating MCOLN1 with ML-SA5 triggers cell death of a number of cancer cells by evoking autophagic arrest and subsequent apoptotic response and cell cycle arrest, with little or no effect observed on normal cells[1].
ML-SA5 in Patu 8988 t xenograft mice profoundly suppresses tumor growth and improves survival[1].
