General description

A macrolide antibiotic that acts as a specific inhibitor of vacuolar-type H+-ATPase (V-type; Ki = 500 pM). A valuable tool for distinguishing among different types of ATPases. Blocks lysosomal cholesterol trafficking in macrophages and is known to interfere with pH regulation in brain cells. Exhibits cytotoxic effects on a number of cell lines in a cell viability assay. Reported to selectively inhibit β-secretase, an enzyme involved in the processing of amyloid precursor protein (APP). The InSolution format with a purity of ≥97% by HPLC in 90% DMSO is also available (Cat. No. 508409).
Note: 1 set = 3 x 10 µg

Subendothelial retention of apolipoprotein B100-containing lipoprotein, such as low-density lipoprotein (LDL), is the initial step of atherogenesis. Activation of autophagy exhibits beneficial effects for the treatment of atherosclerosis. In our previous study, we demonstrated that hyperglycemia suppressed autophagic degradation of

Neurons communicate by the activity-dependent release of small-molecule neurotransmitters packaged into synaptic vesicles (SVs). Although many molecules have been identified as neurotransmitters, technical limitations have precluded a full metabolomic analysis of SV content. Here, we present a workflow to rapidly

Autophagy suppresses mitochondrial metabolism to preserve hematopoietic stem cells (HSCs) in mice. However, the mechanism by which autophagy regulates hematopoietic aging, in particular in humans, has largely been unexplored. Here, we demonstrate that reduction of autophagy in both hematopoietic cells
