Description: Activator of TRPML channels
Chemical Name: 2-[2-(3,4-Dihydro-2,2,4-trimethyl-1(2H)-quinolinyl)-2-oxoethyl]-1H-isoindole-1,3(2H)-dione
Purity: ≥98% (HPLC)
Biological Activity for ML SA1
ML SA1 is an activator of TRPML channels (TRPML1, 2 and 3); does not activate TRPM2, TRPV2, TRPV3, TRPC6 or TRPA1 channels. Induces TRPML-mediated Ca2+ release from lysosomes; activity corrects trafficking defects and reduces cholesterol accumulation in Niemann-Pick type C macrophages. Activation of TRPML1 by ML SA1 causes membrane accumulation of aquaporin-3 and -5, and significant depolymerization of the actin cytoskeleton, in human lymphatic endothelial cells (HLECs).
