Ac-KQKLR-AMC (Cathepsin S substrate) is a biological active peptide. (Cathepsins are a class of globular lysosomal proteases, playing a vital role in mammalian cellular turnover. They degrade polypeptides and are distinguished by their substrate specificities. Cathepsin S is a cysteine proteinase involved in the pathogenesis of autoimmune diseases, atherosclerosis, cancer, obesity and related diseases.This peptide is a cathepsin S substrate fluorescently labeled with AMC (Ex/Em=354 nm/442 nm). It can be used to measure cathepsin S activity.)

EN6-mediated ATP6V1A modification decouples the v-ATPase from the Rags, leading to inhibition of mTORC1 signaling.

2',5'-Dideoxyadenosine is a potent and non-competitive adenylyl cyclase inhibitor via binding the P-site (IC50: 3 μM).2',5'-Dideoxyadenosine (20-150 mM), like adenosine, dependently and reversibly inhibits the positive inotropic and chronotropic effect of beta-adrenergic stimulation with isoproterenol (8-54 pmol) up to 70% and 50%, respectively.
