Catalog Number: 1334
Chemical Name: (3Z,5E,7R,8S,9S,11E,13E,15S,16R)-8-Hydroxy-16-[(1S,2R,3S)-2-hydroxy-1-methyl-3-[(2R,4R,5S,6R)-tetrahydro-2,4-dihydroxy-5-methyl-6-(1-methylethyl)-2H-pyran-2-yl]butyl]-3,15-dimethoxy-5,7,9,11-tetramethyloxacyclohexadeca-3,5,11,13-tetraen-2-one
Biological Activity
Highly potent, selective inhibitor of vacuolar H+-ATPases (IC50 = 0.6 - 1.5 nM in bovine chromaffin granules). Selective for v-ATPase over other ATP hydrolyzing enzymes such as F-ATPases and the H+/K+-ATPase (P-ATPase). Thought to inhibit autophagy either by blocking autophagosome-lysosome fusion (in H4IIE cells), or by blocking lysosomal degradation.
