Biochem/physiol Actions
ML-SI3 is a 4-diastereomer racemate (2 cis and 2 trans isomers) with a cation channel TRPML1-blocking (IC50 = 3.1 μM/trans, 18.5 μM/cis against 5 μM ML-SA1-induced cellular calcium response) and TRPML2-activating activity (EC50 = 3.3 μM/trans, 9.4 μM/cis), while exhibiting much weaker TRPML3 potency (EC50 = 28.5 μM/trans, IC50 = 29.0 μM/cis). ML-SI3 is shown to compete against ML-SA1 for binding the same TRPML1 hydrophobic cavity. Comparing with ML-SI1 (GW405833), ML-SI3 is more potent and not agonist-dependent, effectively antagonizing against TRPML1 activation by both MK6-83 and ML-SA1.

Transient receptor potential mucolipin 1 (TRPML1) regulates lysosomal calcium signaling, lipid trafficking, and autophagy-related processes. This channel is regulated by phosphoinositides and the low pH environment of the lysosome, maintaining calcium levels essential for proper lysosomal function. Recently, several small

Upon nutrient starvation, autophagy digests unwanted cellular components to generate catabolites that are required for housekeeping biosynthesis processes. A complete execution of autophagy demands an enhancement in lysosome function and biogenesis to match the increase in autophagosome formation. Here, we
